E*THIRTEEN chainring Ultralight Guidering Direct Mount Narrow Wide BOOST
The Utralight Guidering is the lightest 1-speed gravel chainring from e*thirteen.
With the SL chainring as a platform, the arm design has been optimized and the chainring strategically machined to achieve minimal loss of impact resistance for large weight reductions. A revised narrow M3 tooth profile eliminates chain noise and reduces overall system wear. With the proven alternating thick-thin tooth profile, it always keeps the chain securely in place. It is suitable for 10-, 11- and 12-speed drivetrains. The UL chainrings are compatible with both Shimano and SRAM.
Note: The UL chainrings have a 5 mm offset (Boost) for use with XCX Race cranks on Boost bikes. If you want to ride an XCX Race crank on a non-Boost frame (142 mm), please use SL chainrings.
