This road bike chainring is specifically engineered for use with SRAM Force 2x 12 speed chainsets. Its tough aluminium build makes it strong & dependable during long days on the road, while its four-bolt pattern makes it easy to swap out your old chainring. Coming complete with updated tooth profiles for enhanced wear as well as a more durable finish, this genuine SRAM direct replacement chainring is perfect for breathing new life back into your chainset. Road Bike Chainring with X-Range Gearing Technology Today’s drop bar bikes are faster & more capable. Riders want a bike with the wide range gearing to match their wide range of cycling pursuits. But, range is only one half of the equation; they also want a drivetrain that offers the right gear for any situation. So, SRAM has developed X-Range gearing. X-Range achieves wider range & tighter jumps by going to a 12-speed cassette, but also by moving some of the gear range from the front of the drivetrain to the back. They've employed smaller chainrings with a consistent 13T difference, while giving the cassettes a 10T-start for wider range (up to 10-36, or 360%!). That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. & when a front shift is executed, the smaller jump is smoother & means that you can get to the right cadence with fewer compensation shifts in the rear. Fewer, faster front shifts make it easier for you to find the right gear, & that’s a distinct performance advantage relative to traditional drivetrains. Technologies:
- Updated tooth profiles for enhanced wear.
- More durable finish.
- X-Range gearing technology gives you more range & a smoother gear progression, so you're always in the right gear. Manufacturer's Part Number: 00.6218.015.004
