Sylvan Race Alloy e*spec All Mountain Wheels


Light. Dynamic. Strength to handle any trail.

Featuring e*thirteen's first-ever asymmetric rims, the Sylvan Race Alloy e*spec All Mountain wheels are the perfect match for light e-bikes catering to both daily trail rides and the occasional adrenaline-fueled descent.

The asymmetric 30mm inside-width rims feature a low rim height profile to increase compliance, absorb impacts, reduce fatigue, and improve traction. The asymmetric profile results in near-equal spoke tension between the drive and non-drive sides, resulting in a stronger wheel and more consistent ride characteristics. The valve dock interface ensures a good seal point for your tubeless valves. These features combined with double-butted spokes and alloy nipples make for a controlled lively ride feel.

The unique e*spec rear hub utilizes an oversized hub shell, large 6808 bearings, a steel axle, and 32 spokes, allowing it to withstand the higher drive torque and bike weight that e-bikes entail. These features also provide longer bearing life and better freehub sealing. The freehub is equipped with a 4-pawl, 3° engagement freehub to ensure rapid engagement, essential for quick accelerations on changing terrains.
