More about e*thirteen Drivetrain Components

Helix cassettes offer gear ranges that exceed SRAM Eagle and Shimano XT, from 9-46T to 9-52T configurations delivering up to 578% range. The two-piece replaceable cluster design means you swap worn cogs without replacing the entire cassette, cutting long-term costs. Full cross-compatibility lets you run Helix cassettes with SRAM or Shimano drivetrains.

Helix cranks pair forged aluminum or carbon fiber construction with a direct mount interface for stiffness and simplified chainring swaps. Race Carbon cranks are among the lightest on the market. E-MTB-specific e*spec cranks are reinforced for motor torque. Gravel cranks accommodate narrower Q-factors for drop-bar geometry.

Vario chainguides keep your chain secure across every discipline. Full coverage DH guides for bike park and racing. Enduro guides that balance protection and weight. Trail guides for lighter setups. E-MTB-specific Core e*spec guides handle the demands of powered riding.

Direct mount and spider-based chainrings in steel and aluminum. Threaded and press-fit bottom brackets with quality bearings and robust seals. Aluminum Plus and Composite Base flat pedals deliver the same 22-pin layout and 100x110mm platform from the original LG1 design.

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