More about e*thirteen Bike Components

Every bike component we make starts with the same question: will it hold up when it matters most? Two decades of World Cup racing have given us the answer, and it's built into everything from our wheels to our chainrings.

Sidekick wheels changed what riders expect from a hub. Pinkbike Innovation of the Year and Design & Innovation Award winner, Sidekick eliminates pedal kickback, runs silent, and spins drag-free. Pair with Flux rims for engineered compliance that absorbs hits without losing precision.

Helix drivetrain components deliver up to 578% cassette range with drop-in compatibility across SRAM®, Shimano®, and TRP® systems. Two-piece serviceable cassettes. Carbon and alloy cranks from featherweight XCX to ASTM 5-rated gravity. M4 narrow-wide chainrings with T-type® compatibility. Vario chainguides with infinite adjustment.

E-MTB riders get purpose-built e*spec components engineered for motor torque and compact motor protection. Gravel riders get ultralight XCX cranks and the 9-45T cassette with 500% range in our gravel bike components line.

Bike parts for every discipline. Built to perform. Built to last. 10-year warranty on everything.
