e*thirteen Direct Mount Chainrings
Available in a wide range of options to suit mosts needs.

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.

 

e*spec Direct Mount Aluminium
Our new direct mount e*spec chainrings use our new M3 narrow-wide tooth profile, which reduces weight without sacrificing chain-retention. In making our SL and UL chainrings lighter and more beautiful than their predecessors, we adapted a similar design to work with Bosch, Brose, and Shimano motor configurations.

Fits - 52mm or 53mm (Boost chainline)
Compatibility - Bosch™, Brose™, Shimano™ & Fazua™
Options - 32t (Shimano only), 34t, 36t, 38t

 

e*spec Direct Mount steel

Our steel direct mount rings provide great performance and long life at a killer price for todays high-performance e-bikes.

Fits - 52mm or 53mm (Boost chainline)
Compatibility - Bosch™
Options - 34t, 36t, 38t
