WTB shared the following info about their new Proterra wheels:

WTB now offers complete wheels at an affordable price! Proterra mountain and gravel wheels are available individually or as a $649.90 wheelset that performs well above its pay grade. Every Proterra hub uses high-quality bearings and a responsive six-pawl freehub design with 3.7 degrees of engagement to deliver the performance you expect of a high-end wheelset without the high-end price tag. Eliminating the frustrations that come with proprietary parts, Proterra wheels combine the simplicity of double butted J-bend spokes with the dependability of Sapim secure lock nipples. Even maintenance should be a positive experience, which is why all Proterra hubs are easily serviced without the need for fancy tools.

Proterra rims are extruded from WTB’s premier 6069 aluminum alloy to optimize strength while a bead blast finish and durable water-transfer decals keep your wheels looking fresh. 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.

Is Proterra Light or Proterra Tough right for you? Proterra Light wheels in gravel-ready 23 and 25mm widths check all the boxes of a fast and light alloy wheelset while the trail-focused 27mm width is optimal for trail bikes with 2.25-2.5” tires. Proterra Tough wheels feature a wider 30mm internal rim width to maximize tire volume while increasing sidewall support at lower pressures. Proterra Tough is the perfect replacement wheelset for those who want peace of mind while bashing their way down rowdy trails as everything else blurs by in the periphery.

Every Proterra wheel benefits from our TCS (Tubeless Compatible System) 2.0 system and ships with the Solid Strip, TCS tubeless tape and black alloy valves already installed. This means all Proterra wheels are ready for tubeless tires and sealant right out of the box. The integral component of our TCS 2.0 system is the Solid Strip, which is a durable strip that lies beneath the tape, prevents it from sagging at the spoke holes, makes it easier to mount a tire and protects from puncture in the case of a broken spoke. In the end, WTB’s innovative Solid Strip results in a more robust tubeless system that increases reliability and is easier to set up.

We believe you shouldn’t have to smash your piggy bank in order to ride dependable products, which is why every Proterra Light or Tough front wheel has an $294.95 MSRP while each rear wheel carries an MSRP of $354.95. Proterra wheels are currently in stock at our California wheel building facility where every wheel is hand-built at the base of Mount Tamalpais.



Proterra Light i27 are everyday wheels for the everyday trail bike. Your bike that does all deserves a wheel that’ll do the same. The open-cavity rim profile eliminates weight where it isn’t needed while also providing a more compliant ride. The responsive freehub ratchets through techy climbs while also providing instant power as you pedal out of corners. The 27mm width rim provides optimal tire volume and profile for tires ranging from 2.25-2.5” wide.


Note: Proterra wheels will initially only be available through WTB.com. WTB will expand the line to the WTB distributor/retailer network in time, but limiting Proterra to WTB.com in the beginning will allow WTB to optimize and adapt the systems they’ve developed at WTB’s  new wheel-building facility.


Proterra Tough i30 wheels keep the trail in check while everything else blurs by in the periphery. Reinforced by our proven dual I-Beam support, Proterra Tough rims feature a 30mm internal width to provide higher tire volume while also increasing sidewall support at lower pressures. Choose Proterra Tough when you need a wheel that won’t let you down. The 30mm width provides optimal tire volume and profile for tires ranging from 2.4-2.6” wide.
