Product Description
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 27mm inner rim width strikes a happy medium on the width spectrum and allows it to provide optimal air volume and casing profile on tires in the 2.3-2.5" range. The open-cavity rim profile eliminates weight where it isn't needed while also allowing for a smoother ride. The responsive 6-pawl freehub provides 5 degrees of engagement and allows you to ratchet through techy climbs while also providing instant power as you pedal out of corners. Looking to go wide on your downcountry build? Even XC is going bigger.
Usage: Cross-Country / Trail

1
Frequency Hub
The world’s best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement.
2
Solid Strip & TCS Tape
Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke.

3-Cross Lacing and Alloy Nipples
Trail wheels need to strike the perfect balance of lightweight performance and daily dependability. Proterra Light i27 wheels provide the longterm reliability of a 3-cross lacing pattern with the weight savings of alloy nipples.

27mm inner rim width
Daily trail riders riding 2.3-2.5" tires often choose rims with an inner rim width of 27mm due to the balance of high-volume sidewall support and lightweight performance. This is the excellent rim width for trail riders who value the climb or XC riders who prefer the descent.

Hand-Built in California
Proterra wheels are hand-built in our California wheel building facility at the base of Mount Tamalpais, where mountain biking began. Our team of wheel wizards lace, tension and tape every Proterra with the same attention to detail they provide their own wheels. This hands-on approach allows us to confidently stand behind our wheels as the most reliable on the market.
TCS (Tubeless Compatible System)
TCS is our standardized tubeless rim/tire system designed to meet international ETRTO standards and deliver unbeatable tubeless performance and reliability. TCS components reduce weight, increase traction, virtually eliminate flats and has established itself as the most dependable tubeless system available. Our TCS system includes tires, rims, tape, sealant and valves to provide a comprehensive package of unrivaled tubeless performance and reliability. Every Proterra wheel benefits from our TCS (Tubeless Compatible System) 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.
Dependable 6069 Alloy
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. 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.
