More about e*thirteen Mountain Bike Components
We started in downhill racing and never forgot where we came from. Every MTB component we make carries that DNA, whether it's headed to a World Cup start gate or your Saturday morning trail ride.
Sidekick wheels won Pinkbike Innovation of the Year by doing what no other hub could: fully disconnecting the drivetrain when coasting. No kickback. Less drag. Near-silent operation. Pair them with Flux rims for engineered compliance that smooths out the rough stuff without going soft in the corners.
Helix cassettes brought real choice back to drivetrains. Up to 578% range, two-piece replaceable clusters, and drop-in compatibility with SRAM®, Shimano®, and TRP® systems. Run what you want, not what someone else decided for you.
Mountain bike cranks span the full range from sub-400g XCX carbon for weight weenies to ASTM 5-rated Helix GR alloy for riders who send it. Vario chainguides offer full coverage for bike park laps or minimalist protection for long days in the saddle. M4 narrow-wide chainrings keep your chain where it belongs, with T-type® compatibility for the latest builds.
Bottom brackets, pedals, and all the parts that finish the build. Everything is backed by a 5-year warranty or a lifetime warranty for carbon rims.
