When SRAM launched the Eagle 12-speed group, we were absolutely blown away by its massive 500% gear range—the same you'd find with many 2x drivetrains—all without dealing with the added weight or annoying miss-shifts of a pesky front derailleur. The massive pulleys in the rear derailleur seemed perfect until we tried to spin them...and tried, and tried. Honestly, the stock Eagle pulleys are probably the worst spinning pulleys we've ever seen. No problem: Ceramitech is here to blow your mind and boost your performance to new heights as you crush the trail and leave your friends whining in the hurt locker far behind.
Each cog set features DELRIN® 510GR construction, a fiber reinforced polymer specially suited to high strength situations where resistance to deflection is paramount, such as every time you shift. The Ceramitech bearings are in-molded for absolute security and durability as well as ease of maintenance. And speaking of maintenance; every set comes with a tube of Kluber IsoFlex NB52 grease and an extra set of seals to keep your pulley set running like new season after season.
These 12T/14T pulleys blow the stock pulleys away when it comes to spin, and the oversize diameter reduces chain pin working angles to eliminate every bit of friction possible.
Sram 12T/14Tceramic pulleys are compatible with:
ALL Sram Eagle 12 Speed MOUNTAIN BIKE GROUP SETS, MECHANICAL AND eTap.
It's a mystery to us why major manufacturers ignore bottom bracket and derailleur pulley performance and continue to pump out under-performing products that sap wattage from riders who are working like mad to get faster. You have the BBInfinite bottom bracket with Ceramitechs already, and you've experienced the tremendous gains. It's time for another step forward toward your goal. Get the most out of your ride by riding Ceramic derailleur pulleys
