More about e*thirteen E-MTB Drivetrain Components

Standard cranks flex and fail under motor torque. e*spec cranks are engineered differently, with reinforced construction and stiffer spindle interfaces that handle the sustained loads of powered riding. Helix Race Carbon e*spec for the weight-conscious. Helix Race and Core Alloy e*spec for durability at a lower price. All feature the same direct mount interface for simple chainring swaps.

Helix cassettes bring the same advantages to E-MTB that changed the game for acoustic bikes. Up to 578% gear range with 9T to 52T spreads. The two-piece replaceable cluster design means you swap worn cogs instead of the whole cassette, which matters when motor torque accelerates wear.

Turbocharger combines a 104 BCD spider, bashguard, and chainring into one integrated system that protects your drivetrain from rock strikes and chain drops. Core e*spec and e*spec Plus chainguides add retention for rough terrain without interfering with chain flow.

Direct mount and spider-based chainrings in tooth counts optimized for E-MTB gearing. Aluminum Plus and Composite Base flat pedals deliver race-proven grip on a platform built for abuse.

Every e*spec component is backed by a 5-year warranty.
