WTB Proterra Tough i30 27.5"Alloy MTB Rear Wheel (Shimano HG-11sp)

Reinforced by our proven Dual I-Beam support, Proterra Tough rims feature a 30mm internal width to provide higher tyre volume while also increasing sidewall support at lower pressures. High-quality EZO sealed bearings are designed to endure through seasons of aggressive riding while a responsive 6-pawl freehub provides the snappy 5 degrees of engagement you demand when cranking out of corners. Choose Proterra Tough when you need a wheel that won't let you down.

Proterra rims are extruded from WTB's premier 6069 aluminium alloy to optimize strength while a bead blast finish and durable water-transfer decals keep your wheels looking fresh. Our extensive testing shows other 6000-series alloy to be less ding-resistant, while stiffer 7000-series alloys result in a harsher ride feel and tend to increase pinch flats. All of this ensures WTB Proterra wheels provide the compliance you expect on the first ride and the longevity you demand for every ride that follows.
