From our previous Guidering M, we were able to shave 11 grams off with our SL Chainring while still increasing fold-over strength and impact resistance.
Months of testing and numerous iterations have yielded a long-wearing shape and finish to make sure your chain stays put even after months of use. Coupled with a clutch-style 10, 11, or 12 speed rear derailleur and proper drivetrain protection, you’ll be ready for anything the trail throws at you.
*SL Guiderings are machined with a -8mm offset and work with BOTH boost and non-boost chainlines, depending on spacer orientation of Gen 3 and 4 e*thirteen cranksets.
Race Face new Cinch Direct Mount Oval rings help you put down the watts in the best part of our pedal stroke. Ovals provide enhanced traction control when compared to conventional round rings, particularly in high torque, low cadence riding scenarios. We arrived at an optimal 10% ovality and 112.5° clocking, which can be achieved in both regular and flipped Super Boost positions by following the orientation callout on the rings. Our variable width tooth design will keep chain retention dialed utilizing clutched derailleurs, and is also compatible with many chainguides. Available in 4 of our most popular sizes, the Race Face Oval Ring gives you the advantage during the toughest part of your ride.
E*thirteen Guidering M chainrings boast a revoluntionary dual width tooth design to help keep your chain locked on your ring and not dropped on the trail. Months of testing and numerous iterations have yielded a long-wearing shape and finish ensuring your chain stays put even after months of use.
