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.
