The WTB Proterra Tough i30 29" wheelset is built to take a beating and come back for more. Designed around a burly 30mm internal width, these alloy rims are optimized for modern trail and enduro tires—offering better support at lower pressures for improved traction and control. Laced with 32 double-butted spokes front and rear, and spinning on high-engagement hubs with Centerlock rotor compatibility and a Shimano Micro-Spline freehub, they’re ready for aggressive terrain and high-torque riding. Whether you’re charging rock gardens or rallying backcountry lines, the Proterra Tough i30s deliver confidence and durability without tipping the scale—or your budget.
