CeramicSpeed CeramicSpeed SRAM 1-11

Upgrade your SRAM XX1/X01 rear derailleur with CeramicSpeed Pulley Wheels for reduced friction and extended lifetime. A breakthrough for SRAM’s MTB systems, the XX1 and X01 rear derailleurs included new tooth designs for both pulley wheels. Because of our commitment to compatibility, we have designed specific pulley wheels that function perfectly as upgrade replacements for the MTB 1x11 SRAM systems.

Aluminium Pulley Wheels
These aluminum alloy pulley wheels deliver a unique mix between low friction and long lifetime improving your performance when riding off-road with your favourite SRAM XX1 or X01 system.

Titanium Pulley Wheels
When it comes to the ultimate pulley wheels for off-road applications, the SRAM 1-11 titanium pulley wheels are by far the most efficient. Available with CeramicSpeed coated bearings, these pulley wheels feature increased resistance to corrosion, and the damaging effects of contaminating factors like water, salt, or dirt are eliminated. This is thanks to a special coating applied to the bearing’s races, which is 75% harder than hardened steel.

In a friction test conducted by independent test lab Friction Facts, the CeramicSpeed Pulley Wheels came through as the lowest friction pulley wheels from a total of 19 market standards. See the complete results here.

Mounting and maintenance
It is very important to install and service these pulley wheels accordingly. Follow the video instructions for mounting of SRAM pulley wheels here. Maintenance is also required periodically. We recommend that you service your pulley wheels whenever you lubricate your chain, after washing your bike, or after riding in wet or muddy conditions. To do so, add CeramicSpeed Oil to the outside of the bearing seal, so that the oil can penetrate the bearing.
