ethirteen Grappler Race Carbon e*spec Enduro Rim Info

Grappler Race Carbon e*spec Enduro Rim is purpose-built for the added demands of full-power e-bikes, delivering the strength, control, and ride quality aggressive trail and enduro riders expect. Engineered with a reinforced e*spec construction, this rim is designed to handle higher system weights and increased torque while maintaining a responsive, confidence-inspiring feel on demanding terrain.

The rim is constructed from high-modulus carbon fiber and features a 30mm internal width optimized for modern trail and enduro tires ranging from 2.3” to 2.6”. This wider profile enhances sidewall support, improves cornering stability, and increases traction, allowing riders to carry speed with greater control while reducing rider fatigue over long descents.

A low-profile rim height plays a key role in ride quality, adding vertical compliance that helps absorb impacts and trail chatter. Compared to standard analog versions, the e*spec rim includes additional reinforcement to withstand the forces generated by full-power e-bikes, with only a modest weight increase of approximately 50–60 grams.

The Grappler Race Carbon e*spec Enduro Rim is tubeless compatible with a hookless bead, making it easy to build a reliable tubeless wheelset focused on grip, durability, and efficiency. Like all e*thirteen carbon rims, it is backed by the brand’s Lifetime Carbon Rim Warranty, giving riders the confidence to push harder and ride farther.
