Introduced at Eurobike, the made-in-France CyclingCeramic Oversized Pulleys are now available on their website for pre-2017 Shimano and SRAM road bike derailleurs.
Their upcoming SRAM eTap will follow “very soon” and parts for the latest Shimano R9100 (Dura-Ace) and R8000 (Ultegra) will be here “before Spring” according to the company’s announcement. SRAM eTap, Shimano R9100/R8000 (Dura-Ace & Ultegra) versions are also now available.
The 16-tooth pulley wheels are machined from aluminum and roll on ceramic bearings (naturally), which are sandwiched in a UD carbon cage. Titanium screws hold it all together. It’s sold as a complete system that replaces the stock cage/pulley on your rear derailleur. It’s available in black or red, plus the limited edition orange/gold shown here.
CyclingCeramic claims they’ve lab tested their system to save 2.7 watts, or the equivalent of one minute shaved off a 20km time trial (speed not disclosed). Retail is €329 and comes with a two year warranty against manufacturer’s defects.
