  • £349.99
  • RRP £439.95
  • Saving you £20

Chosen by World Champions and top athletes around the world, the CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world. Featuring an industry-leading design, this limited edition model is for Shimano Dura-Ace 9200 and Ultegra 8100 systems with an integrated stop tower for simple installation and durability. This OSPW System has hand-built CeramicSpeed Bearings installed in each pulley and it comes with a four-year CeramicSpeed warranty as standard and a lifetime CeramicSpeed warranty when choosing coated bearings (please choose option from the menu). Since its introduction in 2015, the CeramicSpeed Oversized Pulley Wheel System has been through 13 unique derailleur compatibility developments. No other pulley system has the depth of use and trust as the CeramicSpeed OSPW, which counts both Men’s and Women’s Triathlon World Champions, World Tour professional road teams, XCO professional MTB Teams, and elite athletes worldwide as its users. CeramicSpeed Shimano R9250/R8150 OSPW System Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur. The upper and lower oversized aluminium pulley wheels come fitted with either standard or coated CeramicSpeed Bearings. Please Note: While there are visual similarities in the 9100 Series OSPW and 9200 Series OSPW, the spring tension settings, rotation stop tower placement, and mounting pin depth are slightly repositioned and as such the systems are not cross-compatible. For 8100 derailleurs, the cage uses the factory derailleur body washer. 9200 derailleurs will require the new included derailleur body washer. Technologies: - The overall power savings of the OSPW System for Shimano Dura-Ace 9200 and Ultegra 8100 reach 30%-60%, or more in some cases, over a stock setup. - The oversized pulley wheels have 3-5 times longer lifetimes than the commonly used standard pulleys on the market.

This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner. Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven Servo Wave technology.

Your time on the bike is precious, let Shimano make it even better. Servo Wave Precise Braking ControlWhen you pull a Servo Wave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
