More about e*thirteen MTB Drivetrain Components

Helix cassettes changed the game. Up to 578% gear range beats both SRAM Eagle and Shimano XT. The 9T small cog means a higher top speed without sacrificing climbing gears. And the two-piece replaceable cluster design lets you swap worn cogs instead of buying a new cassette every season.

Helix cranks match that engineering. Race Carbon versions rank among the lightest production cranks available. Helix Alloy cranks deliver the same stiffness and direct mount interface at a lower price point. LG1 Race Carbon for gravity. TRS Race Carbon for trail and enduro. XCX Race Carbon when every gram matters.

Vario chainguides keep your chain where it belongs. Full coverage DH guides for bike park days and race runs. Enduro guides for protection without the weight penalty. Trail guides for riders who want security without bulk. All feature robust backplates designed for years of abuse.

Direct mount chainrings in steel and aluminum with teeth optimized for chain retention. Helix Race rings work with e*thirteen cranks. 3-bolt direct mount options fit SRAM cranks. SL Guiderings and UL Chainrings for integrated retention. Threaded and press-fit bottom brackets with sealed bearings built to survive wet, gritty conditions.

Aluminum Plus and Composite Base flat pedals complete the cockpit with the same 22-pin layout and 100x110mm platform from the original LG1 race pedal. Thin profile clears rocks. Rebuildable design lasts for years.

Every drivetrain part is backed by a 5-year warranty.
