WTB PROTERRA Tough i30 29" rear wheel, 6-bolt, 12x148 mm, Shimano MicroSpline
The Proterra Tough i30 wheels are lightweight alloy enduro wheels that won't disappoint. The 30mm internal rim width provides an optimal profile for wider tire widths. Proterra Tough rims are reinforced with the proven Dual I-Beam support and at the same time increase tire sidewall support at lower pressures. The hubs were not spared either, as they are equipped with top-quality EZO bearings, and the rear hub is fitted with a 6-pawl freehub with a 5-degree engagement. In short, Proterra wheels provide the look, sound, and feel you expect from high-end wheelsets.
