Lighter, stronger and better looking than our original Guiderings; the Guidering SL is intended for use on TRS, LG1 and legacy e*thirteen cranks.
The Guidering SL is -8mm offset. This offset will achieve both boost (52mm) and non-boost (49mm) spacing on e*thirteen cranks that feature adjustable chainline (2019 and newer TRS & LG1). On legacy and XCX cranks the Guidering SL will achieve a 49mm non-boost chainline.
Dedicated Boost and SuperBoost chainrings can be found HERE.
SL Chainrings are not compatible with Helix cranks. Helix cranks require Helix rings.
