Answering the demand of riders worldwide, CeramicSpeed has broadened the compatibility of the most efficient oversized pulley wheel system available on the market with a new offering. The CeramicSpeed OSPW System can now complete its Shimano offering with the new 9100 series compatibility. The new OSPW System features a 13/19T pulley wheel combination and can fit cassettes of up to 32t.
13/19T pulley wheels
Because of the design of the 9100 derailleur, the R&D team at CeramicSpeed has tested and concluded that the best performing combination of oversized pulleys is 13-tooth upper and 19-tooth lower pulley. The design of the original derailleur does not allow for a pulley wheel to be larger than 13-tooth in the upper slot. With the 13-tooth upper pulley in place, there was more space for the lower pulley, and thus the 19- tooth option was found optimal.
Bigger pulleys, increased longevity
The entire design of the OSPW System for Shimano 9100 series is very strong and stiff, ensuring a high durability factor. In-house tests show that the bigger number of teeth on pulley wheel the longer pulley wheel lifetime. Since the lower pulley is the one most exposed to wear, the 13/19T combination is a great advantage for durability.
30% less friction
Compared to the original Shimano pulley wheels, in-house tests have shown 30% less friction in the new CeramicSpeed OSPW System. Thanks to the high-quality CeramicSpeed bearings, lightweight components and proven design, the OSPW System for Shimano 9100 series improves the bike performance of any rider.
Tested both in the lab as well as on the road, Team Dimension Data for Qhubeka rider, Nathan Haas, has already finished in 4th place at the Amstel Gold Race, riding with the new CeramicSpeed OSPW System for Shimano 9100. He adds that “CeramicSpeed is an awesome partner to work with as their products simply make riding bikes smoother. I especially like the OSPW System, it’s the future!”.
