Helix R 3-BOLT DIRECT MOUNT

With an e*thirteen Helix cassette and a SRAM™ crank, you can now run Helix 3-BOLT DIRECT MOUNT rings. Designed to function equally well with SRAM™ and Shimano™ chains, this ring brings insane amounts of CNC detail as well as being offered in anodized colors to match our cassettes as a system. Our exclusive 9T cassette is best enjoyed with a 2T smaller front ring to get the full benefit of less chain and more clearance and range for the same gearing at the top and even lower at the bottom. Designed to be strong and light weight, this ring is specific to SRAM™ 3-BOLT DIRECT MOUNT Crank Arms.

Guidering M - Boost
With -5mm BOOST offset. 7050 aluminium and available in 28-38T options. Step-up to better chain retention with the Modified Guidering! Optimized tooth profiles and chamfers provide greater chain retention than standard rings. Coupled with a clutch-style 10 or 11 speed rear derailleur and proper drivetrain protection, you’ll be ready for anything the trail throws at you.

SL Chainrings
Shave over 11 grams from our original Guidering, and update the design to not only look better, but perform 30% better in impact and you have our SL Chainring.

SL Chainrings are -8mm (non-Boost) offset, for use with most e*thirteen cranks (except XCX Race & Helix cranks).

SL Chainrings are not compatible with Helix cranks. Helix cranks require Helix rings

Updated M3 narrow-wide tooth profile eliminates chain noise, and decreases overall system wear.

Chainline
TRS/LG1 Cranks: UL Chainring for SuperBoost chainline. SL Chainring for non-Boost and Boost chainline.

XCX Mountain Cranks: UL Chainring for Boost chainline. SL Chainring for non-Boost chainline.

XCX Gravel Cranks: UL Chainring for non-Boost chainline (142mm rear hub spacing)

Compatibility - 10/11/12 speed. Compatible with both Shimano™ and SRAM™ 12 speed drivetrains.

Compatible with - Legacy e*thirteen cranks with direct mount interface, All TRS Cranks, All LG1 cranks.

Not compatible with - Helix

28-38t options

XCX Ultralight (UL)
UL Chainrings are the lightest 1x XC/Gravel chainrings on the market. Using the SL Chainring as the platform, we tweaked the arm design and strategically machined the chainring so that only minimal sacrifice was made in impact strength for large gains in weight reduction.

UL Chainrings are -5mm (Boost) offset for use with XCX Race MTB cranks on Boost bikes. If you're installing XCX Race MTB Cranks onto a non-Boost (142mm) bike, please use SL Chainrings. ALL XCX Gravel applications will use the UL ring.
