Our Derailleur Pulley Wheels have been a consideration in how to deliver a truly optimised driveline solution, from inception. In partnering with cSixx, we have found a group of passionate engineers and designers, already manufacturing a heavily refined and field-proven product.

Our focus with Derailleur Pulley Wheels has been security and longevity, in the challenging environment of World Tour racing. With a highly refined tooth design and precision manufacturing, cSixx has been the perfect partner for our venture into driveline solutions, where security and wax clearance can be achieved, while minimising unnecessary friction maximising pulley size.  

Available in 12t guide and 14t tension, our Derailleur Pulley Wheels are the maximum size that a standard Shimano rear derailleur cage can accommodate. Spinning on ceramic-hybrid bearings, our pulley wheels offer longevity and smooth running, in real world cycling conditions. Our bearing covers come in both 11sp and 12sp specifications, ensuring a precise fit in the original derailleur cage.

Why we created the Sync Driveline?

Creating the best 1X chainring requires consideration for the whole driveline system. Our driveline gives due credit to chainring design, the chain, chain guide and pulley wheels. Collectively, these components come together to deliver a robust, hard wearing, and efficient driveline.
