E*THIRTEEN Chainring Ultralight Guidering Direct Mount Narrow Wide BOOST
The Utralight Guidering is the lightest 1-speed gravel chainring from e*thirteen.
Using the SL chainring as the platform, the arm design was optimized and the chainring was strategically machined to achieve minimal impact resistance sacrifices for large weight reductions. A revised narrow M3 tooth profile eliminates chain noise and reduces wear on the overall system. 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 drives. The UL chainrings are compatible with both Shimano and SRAM.
Note: The UL chainrings have 5mm offset (Boost), for use with XCX Race cranks on Boost bikes. If you want to run an XCX Race crank on a non-Boost frame (142 mm), please use SL chainrings.
