There are trails to be conquered out there and the wheelset to help us do it all is the Proterra Tough I30 29in Boost Wheel from WTB. Whether we're riding in the brand's PNW home or out here in Utah with the Herd, we can count on the aggressive design of the Proterra Tough I30 to keep trails in check. A 30mm internal width provides higher tire volume, but it also does the job of increasing sidewall support when we're riding at lower pressures over rocky, rooty terrain. And, it's all supported with Frequency hubs that feature a responsive 6-pawl freehub and snappy 5 degrees of engagement.
