The Shimano DA9100-ULT8000 OSPW gearbox is designed and developed entirely by CeramicSpeed, the oversize wheel system provides maximum optimization of your bike’s transmission. Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur. This OSPW X system has a custom molded carbon fiber cage for lightweight and durability. The 4 settings of the tension spring allow an optimal configuration of the transmission based on the driving conditions. OSPW X is specifically designed for road, gravel and cross-country cycling, and is proven on platforms such as the Paris Roubaix, Strada Bianche and CX World Cups.

Fits cassettes up to 36 teeth (range 11-36). This OSPW system reduces friction by 35-40% over the standard pulley configuration. The oversized pulley wheels have 3-5 times longer lifetime than the commonly used standard pulleys on the market.
