Kevin Quan Gives Diamondback’s Andean Life and Speed



Diamondback’s new bike is the fastest bike in the world. Really. Flipping the world of bike engineering on its head, Kevin Quan and his team of engineers designed the Andean from the wheels up to create the most aerodynamic bicycle in the world.

“We set out with Kevin Quan Studios to build the fastest triathlon bike on the market, with no concern for the arbitrary limitations placed on bicycle design by the UCI,” said Diamondback product development VP Michael Brown. “Our Computational Fluid Dynamics (CFD) analysis and unique, best-in-class wind tunnel testing at the University of Toronto shows that we’ve succeeded in that endeavour.”

Kevin Quan, for his part, told Trizone he first started designing bikes in 2003. “From 2003 until 2008, I was senior engineer at Cervelo,” he said from the Paradise Bar in Kona.

“I was the product lead  for the first carbon P3 and the first S-bikes, the first carbon S-bikes,” Quan said, adding that in 2008, together with two colleagues he launched his own design studio in Toronto. “One of my first customers was Diamondback.”

Quan emphasised that his key strengths centred purely on the design side of products. “CAD is just a tool that we use to communicate to the manufacturing [division] what we’re actually trying to describe,” he said. “It’s just like a pencil for an artist; they’re experts in the pencil [itself] but that’s the tool that they use.”

Flipping the world of bike engineering on its head, Diamondback, along with Kevin Quan and his team of engineers, designed the Andean from the wheels up to create the most aerodynamic bicycle in the world. “I have an industrial designer and we have five engineers,” he added. “We started with the [former] and I said: ‘How about it? Give me whatever crazy things you think’.”

Quan said that this process yielded a myriad of potential design ideas and prototypes, in fact far too many from which to select. “I then drew on my experience recently of designing wheels and said that from an aerodynamic standpoint are very difficult to optimise in the middle part,” he added.

“The top and bottom are already aerodynamically efficient, but the middle part isn’t, and that’s where we started,” explained Kevin.

“I said to my designer: ‘Give me a silhouette that looks really good, but fills up… so there’s no space. Then we can make the fastest bike in the world.’” And Kevin’s designer did exactly that, and once the drawings were read, he just said ‘That’s it!’


Designing the bike according to a systemic approach, the Andean was made by fully integrating HED’s Jet 6 Plus wheels into the frame design, planning for a 24mm tire in the front and 26mm in the rear. Due to its ‘from the wheels up’ approach, the frame was created with an ‘Aero Core’ design to minimise drag, and has a unique inbuilt storage system that’s helping make the classic strap-on nylon bags redundant. While the final design aspects sound straight forward, it’s the remarkably complex scientific methods used in creating the Andean that have produced the world’s fastest road bike.

Software Calibration Gives Kevin a 2 Year Lead on any Competition

Kevin Quan’s engineering studio uses the complicated fluid dynamics of other firms as well as the KS1 model, but it’s their unique software calibration and laser diagnostic testing that enabled the birth of the Andean.

It began with a four-year collaborative project over the past two years involving Dr. Philippe Lavoie of the University of Toronto Institute for Aerospace Studies (UTIAS), his graduate students and their half scale wind tunnel.

“The tunnel has a rotating table, drums to spin the wheels and it’s all calibrated to the forces of bicycles. We built 50% scale models, including a rider,” explained Kevin. “This is where most other companies stop. They accept the numbers from their software and create a product from there.” But Kevin and his team pushed further.

“After getting numbers from the model in the tunnel, we fed those back into the software so it could become more predictive. You want to have an iterative cycle where you get your wind tunnel results, then calibrate your software to where they match.”

This approach meant Kevin Quan’s software had become predictive to the most precise degree. “It’s our trade secret. It’s not about the software we’re using, it’s that we put in the time to make it reflect what it is in the real world,” he noted. By utilising laser diagnostic testing, the researchers were able to measure the flow around the frame, plus the field of flow around specific elements like the cockpit, rear triangle and bottom bracket.

Rather than hinder development, the tunnel’s half scale size was of huge benefit. Due to the scaling of the tunnel, the team were able to adjust the turbulence more precisely, which helped them replicate both real world weather conditions as well as a raft of different riding conditions such as riding solo, in front of the pack and at the back of the pack.

“Often, manufacturers look at the frame in a vacuum without consideration for how it interacts with the rider or other components of the bicycle. By taking the integrated design approach, we were trying to see the rider and bike as the wind does – one unit fighting against aerodynamic drag,”said Diamondback.

It’s this unique approach to problem solving and design, along with his canny ability to turn everything on its head and create his own approach that has led Quan to create the fastest bike in the world. Although it’s fair to say he did have some pretty brainy help.

“We have a professor and grad students who have to get all the details right. If they publish in the academic world, it has to be spot-on! It’s not like other companies who cut corners to get market research, this was academically based,” he said.

Project Runway for Bike Design

Chatting with Kevin, you get the feeling you’re speaking with a true genius who’s been in the bike engineering game a while.  It’s been a two year process to create the Andean. “It’s a bit like Project Runway,”  said Kevin, describing the process of designing the world’s fastest bike. With so many different bike-related sports, it was Diamondback’s own history that started the journey towards the Andean.

“Phil Howe, President of Diamondback, was a finisher at Kona in the 80’s,” noted Kevin. “He was really keen to do a triathlon-specific bike.” This, plus Diamondback’s purchase of the Centurion line of triathlon bikes provided the final direction Kevin needed to get started. But they needed a point of difference, so they asked the athletes what they needed.

“Other brands survey ten of thousands of age groupers and riders, but we just wanted to ask the best,” continued Quan. “We sent out surveys to Diamondback’s three triathletes who then forwarded it to their peers. They told us it was all about the container. They wanted more stuff so they could self sustain for the whole race.”

Eager to move past the standard nylon bags with zippers athletes usually fill with their in-race nutrition, Kevin went to work on customising injection moulded plastics, rubbers and magnets to create storage boxes that become part of the bike. He succeeded, and the Andean allows riders to carry three water bottles, three bars, ten gels and an extra tube. By integrating usability with design, Kevin has created the difference that really helps athletes improve their longevity, without compromising on the all-important aerodynamics.

For those that love data, here’s how the bike performed in the wind tunnel


Run 1 (gray line)
This is the baseline test using a Diamondback Serios with HED Jet 6 wheels front and Jet 9 rear with Continental Attack/Force tires (22mm and 24mm), HED Corsair Aerobar, with no storage components. The Serios has been tested in the past against industry benchmarks such as the Cervelo P5 and Trek Speed Concept. The Serios’ strength is high yaw performance – almost 33% faster at 15 degrees yaw vs the competition but gives some back at zero yaw (about 5%)

  • Serios Baseline W
  • Front Wheel: Hed Jet 6
  • Rear Wheel: Hed Jet 9

Run 2 (turquoise line)
This is a comparative test of the new Diamondback Andean with identical setup to the Serios Baseline. The Andean was designed to surpass the competition at low yaw while maintaining the large advantage at high yaw that the Serios displayed. This successful test con rms that the Andean is 10% faster at zero degrees than the Serios and an even more impressive 32% less drag at -15 degrees. This is completely attributable to the Aero Core and fairing of the crank.

Run 7 (red line)
This is a ‘fastest con guration’ test of the Diamondback Andean with HED Jet 9 front wheel, HED Jet Disc, Force/Attack tires, HED Corsair, and Andean Storage accessories. In this con guration, competitive triathletes can store a full race compliment of food and liquids while maintaining industry leading aerodynamics. The Diamondback Andean demonstrates that it is truly the fastest triathlon bicycle in the world.

Kevin’s Biggest Tip for Purchasing a Bike

Start with the tyres, then the wheels, then the frame then the rest of the bike. “A lot of consumers do everything backwards, starting with the bike, then wheels. Because of the inflation and size changes from a 25mm to 28 once inflated, you should really start with the tyre.”

Review: Suunto 3 Fitness. A Fitness Watch for Beginners



The Suunto 3 Fitness is the latest release from Suunto, a brand well known to triathletes. Straight away you can tell by its sleek looks that Suunto wants you to be wearing this watch 24×7, in direct competition with the Apple watch and the latest Garmin. Its looks belay its price, and you will seriously struggle to tell that its a fitness watch at all once on.

To that end, I would say the Suunto 3 Fitness is more of a fitness companion for the fitness and wellness crowd (you know those people in activewear taking up valuable coffee shop spots) instead of a dedicated triathlon watch, and in this area, it does a reasonable job.  However, this is a triathlon specific website and content, so I’m going to review the watch from a triathletes perspective.

Suunto 3 Fitness is a cool looking watch for everyday use.


Top end features

First off the positives. The Suunto has a few surprising top-end features, given the price. The first is it has an integrated heart rate monitor, which for me when compared to my Garmin Fenix 5, was very accurate. During my runs, it seemed to capture my heart rate accurately, within a few beats of my Garmin heart rate strap.  It’s a pleasing feature, which means you can go strapInbuiltt of the time.

Inbuilt heart rate monitor with high-end features

Battery Life

This is where the Suunto shines. Suunto officially says that the watch will last 30 hours when connected to the phone for GPS and five days with standard health tracking and Bluetooth notifications etc.

My testing showed far better numbers with the watch lasting a good two weeks, packed full of full distance Ironman training. For those that hate charging this watch is a godsend.

Movescount is gone, tell your mates, when you can connect

Suunto took the opportunity to update their rather sparse Movescount platform with a new updated Suunto App. It’s indeed a huge step up and in my opinion visually better than Garmin Connect.

It measures the usual suspects, heart rate, calories etc., but also EPOC – which measures post-exercise oxygen consumption. An interesting stat that is based on the fact that your body uses more oxygen post-exercise than during (for a period of ~48 hours), therefore burns more calories than during the event. I can see this reasonably handy for exercise-induced asthmatics, to help regulate their use of medication.

One feature that I quite enjoyed was the ability to track pace and effort on the Google map of your run, which helps to explain to your coach why your pace dropped up the hills.

Track your performance using Google maps

Also, you have the option of posting your run’s Strava style within the app. Its a bit kitschy given we all use Strava, but it can help if you’re looking for local running buddies.

Ability to post publicly is a cool, albeit scary proposition

One major problem is that I struggled to connect the watch to the App, most of the time. It is an arduous process that I found would only work if I deleted and re-paired the watch – a fiddly workaround for sure.  To be fair though, the product is new, and I recall early Garmins having the same problem, so I’m sure it will sort itself out over time.

Peripheral connectivity

I’ve always struggled with Suunto’s decisions around limiting connectivity in their watches, and this is no different.  To use an external heart rate monitor or monitor cadence or speed on your bike, you need to buy yourself one of the Suunto Pods.

Now, this is in a similar vein to traditional fitness watches such as Apple or Samsung, however, as a triathlete, this closed system doesn’t cut it.  Personally, I have an ANT+ power meter, Bluetooth smart trainer, ANT+ and Bluetooth heart rate monitors, ANT+ bike head units, the list goes on, and I cannot connect any of these peripherals that I use day to day.

Now one can say that most triathletes tend to go overboard on gear, to which I can personally attest, however, all my equipment actually gives me an idea as to how to race and train, and not being able to talk to it is a big no-no to me.

Now the big hairy no-no. No inbuilt GPS

The watch pairs to your phone to leverage the inbuilt GPS of the phone and contains only an accelerometer in the watch. This, in my opinion, is a critical oversight, particularly for triathletes.

The first thing that I noticed was the huge discrepancy between the accelerometer and the GPS. The accelerometer was almost, 1min/km quicker, which had me on an easy run running 4min/km pace. While this is great for my ego, it’s terrible when trying to prepare for a race.

Pairing the watch to my phone didn’t give much better results with a 30-second difference. Given the watch uses my phone’s GPS, you’re always going to get vastly different results when compared to both Suunto’s and Garmin’s higher grade watches.

Secondly, as triathletes, for the most part, were not allowed to race with a phone, which effectively means you need to get a watch for training and one for racing. Inconceivable!


As I mentioned at the start of this review, the new Suunto 3 Fitness polarised me somewhat. On the one hand, its a pretty solid fitness watch packed full of top end features at an entry-level price.

But as a triathlete, its lack of GPS and dependency on the phone effectively eliminates it use during race day. So, unfortunately, it’s a big thumbs down from me. Save your pennies and get a Suunto Spartan, or even better choice a Garmin 935XT.

The Sufferfest Releases a New Range of Indoor and Outdoor Plans to Cover Just About Anyone



The Sufferfest, a comprehensive training app for cyclists and triathletes, announced the release of 67 new training plans on TrainingPeaks, creating a library of over 100 free plans for a novice, intermediate, and advanced endurance athletes. The plans incorporate indoor sessions from The Sufferfest’s catalogue of structured workouts, technique drills, and outdoor weekend sessions to better accommodate year-round structured training. Integration with TrainingPeaks—the industry leader in digital training solutions—allows athletes to take advantage of advanced data analysis and performance management features.

Designed by elite coaches Mac Cassin and Neal Henderson at APEX Coaching, the new collection of training plans from The Sufferfest includes plans designed to prepare athletes for specific events like triathlons, time trials, metric centuries, full centuries, mountainous gran fondos, and sportives. The outdoor workouts are built using TrainingPeaks’ Workout Builder, allowing them to be easily exported to compatible cycling computers or fitness devices. Optional yoga and mental toughness sessions can be added to any plan, further cementing The Sufferfest as the only training platform to provide comprehensive training for an athlete’s body and mind. To access all 102 plans, all users need is a subscription to The Sufferfest and a free account with TrainingPeaks.

“Many athletes lose focus and structure when they transition to riding outside in the warmer months,” said Cassin. “The new event preparation and outdoor/indoor plans are perfect for athletes who don’t want the quality of their training to go out the window when they head out the door. And because the plans are designed around an athlete’s Four-Dimensional Power profile, they are much more effective than generic plans that don’t take a rider’s unique strengths and weaknesses into account. Once an athlete completes the Full Frontal fitness test in The Sufferfest app and gets their comprehensive power profile, they can choose a plan that is tailored to develop their overall fitness while driving improvements in the area they need it most—whether it’s sprinting, sustained efforts, VO2 efforts, or repeated efforts.

“A training plan is only as good as the coach who designed it,” said David McQuillen, CEO of The Sufferfest. “Our partnership with APEX Coaching gives every athlete with a subscription to The Sufferfest access to the same coaches who train the best cyclists and triathletes in the world. By adding these new training plans we’ve expanded the ability for endurance athletes to take advantage of the most innovative, cutting-edge sports science available, no matter what the weather or time of year.”

A New Workout to Build Muscular Endurance from The Sufferfest



The Sufferfest, a comprehensive training app for cyclists and triathletes, today announced the release of their latest endurance workout, G.O.A.T. Adding to their library of over 50 structured interval workouts designed by elite coaches, this session features officially-licensed footage of the Swiss Alps from The Col Collective.

G.O.A.T. is a 42-minute interval workout created by world-renowned coaches Neal Henderson and Mac Cassin from APEX Coaching. Designed to help athletes develop neuromuscular coordination and muscular endurance, G.O.A.T. is built around eight, two-minute, low-cadence intervals. Using The Sufferfest’s proprietary Four-Dimensional Power™ platform, every interval is precisely calibrated to the rider’s personal fitness level. Each effort corresponds with a climb up some of the most iconic passes in the Swiss Alps. Mike Cotty, legendary endurance cyclist and founder of The Col Collective, serves as a tour guide during the workout, providing insight into the unique character of each climb.

“To be efficient on the bike you need to engage as many muscle groups as possible, including your glutes, quads, and hamstrings,” said Cassin. “The high-torque, low-cadence efforts in G.O.A.T. are one of the best ways to improve your ability to effectively recruit and coordinate all of the muscle fibres in your legs and develop a smooth, powerful pedal stroke. Because of the demands of generating high power at a low cadence, the workout puts a similar amount of stress on your body as a much longer base ride, making it a perfect session for building muscular endurance and boosting FTP.”

“We continue to build our library of structured workouts to help time-crunched athletes target specific aspects of their Four-Dimensional Power profile and get maximum benefit with minimum time investment,” said David McQuillen, CEO of The Sufferfest. “The focus on low-cadence, high-torque efforts in G.O.A.T. gives the same muscular endurance benefits as a three-hour base ride, all in under 45 minutes. Add the Col Collective’s incredible footage, Mike Cotty’s singular commentary, and the motivational push of some Sufferlandrian Laser Goats, and you have the makings of a classic workout.”

Suunto announces today the new Suunto 9 – a multisport GPS watch designed for athletes who demand the best from their sports watch. Suunto 9 delivers an amazing battery life – up to 120 hours with GPS and an intelligent battery life management system with smart reminders to ensure your watch will last just as long as you need it to. The robust Suunto 9 is made for long, arduous training and racing, and it is tested to the extreme with thousands of hours testing in the toughest conditions.

Suunto 9 is compatible with the new Suunto app that keeps a log of your training, daily activity and sleep, and enables sharing your training logs and engaging with others in the Suunto app community.

Suunto 9 collection

Intelligent battery technology with smart reminders

Three predefined battery modes – Performance, Endurance and Ultra – deliver from 25 hours to up to 120 hours of recording time with GPS tracking on. Additionally, you can create custom battery modes to best suit your needs. When you start a recording, you’ll get an estimate of how much battery life you have left with the current mode. If it’s not enough, switch to another mode at any time.

In addition to the battery modes, Suunto 9 uses smart reminders to help you ensure you have enough battery for your next adventure. Some reminders are preemptive based on, for example, your activity history to make sure you are fully charged for the next outing. If the watch notices you are running low on battery during an exercise, it will automatically suggest changing to a different battery mode.

Tested to the extreme – thousands of hours testing in the toughest conditions

Suunto 9 is designed and built to meet the demands of professional athletes. Tested to the extreme with thousands of hours of real use in the toughest conditions by Suunto’s internal testing team and athletes all over the world, it is your trusted companion to confidently see you through any adventure.

“Durability and precision, attributes at the core of Suunto design heritage, are highly valued by our athletes, and one of the elementary reasons they trust and choose us,” comments Markus Kemetter, Suunto Product Line Manager. “To ensure this, we put the Suunto 9 through vigorous testing. First in our testing laboratory, exposing the materials and the build to various elements and forces, including drop, freeze/thaw, humidity and immersion, and later by our skilled and passionate team of field testers and athletes, who for months have used the watch in their training and everyday life.”

“When talking about training or racing tools for any adventure or endurance sport, the first thing I consider is durability, because it actually gives you the chance to just focus on what you need to do”, comments Mauricio Méndez Cruz, Suunto triathlete and Xterra World Champion. “For me, GPS track accuracy during training and racing has become, not a tool, but a weapon of choice and by this I mean that with it I have become a lot more precise, efficient and confident on my moves during racing – which, at the end of the day, is what makes me be at the top of the podium”, he concludes.

Suunto FusedTrack™ for more accurate track and distance

On long ultra runs, battery life is often the limiting factor for recording distance and track accurately, as GPS is a heavy drain on the battery. Suunto’s unique FusedTrack™ algorithm combines GPS and motion sensor data to improve track and distance accuracy. This allows you to extend battery life by lowering GPS power without significantly compromising accuracy.

True to Suunto’s sports expertise, Suunto 9 is packed with over 80 sports modes and delivers convenient wrist heart rate measurement from Valencell Inc. The watch comes with full GPS route navigation, sunrise/sunset times, storm alarm and many other great features for athletes and outdoor adventurers.

Review: Zone3 Activate Triathlon Range Introduce more Vibrancy and Comfort



I am sure I’m not the only male triathlon aficionado that gets a bit sick of the standard blue and black drab garb that we have to hoof around in. Zone3 is mixing it up a bit for both male and female athletes by introducing a bit more variety and colour in their range.

For those that don’t know Zone3, it is a 10-year-old UK triathlon brand. Born out of university by a team of athletes. Zone3 is more commonly known for their incredible wetsuits and sponsorship of top end triathletes such as the Ironman Texas and world record holder Tim Don.

Zone3 target their triathlon appear at the beginner/intermediate level triathlete, however, the features and comfort performance competes against the top end brands in the market.

Activate Tri suit smooth lines and sharp colours


I was lucky enough to try out both the Activate Trisuit one piece and the Activate two-piece top and shorts. Both products have a truck load of features, but the key ones are:

  • A TriLite, triathlon specific chamois, that’s sized to help us run and swim without impediment
  • Flat locked seams and zips to avoid irritation
  • Silicone UFO grippers specifically built for triathletes, that grip on the inside of the knee

Comfortable chamois

Field Testing

I took both the products through an open water and pool swim, a couple of 20km runs and a few 6-hour rides and I have to say I was impressed by the comfort of both products. The overlocked seems and tri-specific chamois didn’t produce any level of rub or chaffing and I didn’t notice any level of interference with my abysmal swim kick.

Striking colours and design

One major, frankly outstanding feature for me is that the UFO grippers are beyond just marketing hype. They prevent the shorts from rolling up, something that anyone trying to wrestle on a wetsuit in the dark on race morning will attest to as a complete pain in the neoprene.

Looking good on race day

Now I did mention the snazzy colour scheme before and the Zone3 triathlon apparel doesn’t disappoint. With a variety of colours and fancy designs, you will certainly look brighter than the normal triathlete, just make sure to wipe the snot off our face to maximise photo opportunities.


What is truly amazing about these products is the price. At $120 for the full triathlon suit and $90 individually for the top and shorts, the Zone3 triathlon suit range represents phenomenal value for money given the pricing and feature set. Combined with online sales you could easily deck out a whole seasons racing and training wardrobe for half what you would pay anywhere else.

  • Features
  • Design
  • Value for Money
  • Durability


Great value for money with striking good looks.

- Well priced
- Top end features

- Could do with a larger range of cool colours
- Durability could be a problem with lower cost materials, but time will tell.
