Product Description

Proterra Light i23 wheels check all the boxes for a fast and light alloy wheelset. The 23mm inner rim width provides the optimal tire profile for adventure road and gravel tires ranging from 30-42mm. Its open-cavity profile features thin, weight-optimized walls that provide the perfect blend of stiffness, resilience and efficiency. Subdued graphics on a bead blast finish ensure these wheels won't clash with the colors of your dream bike. We didn't skimp on hubs either. Top-tier EZO bearings, a swift 6-pawl freehub and 5 degrees of engagement provide the look, sound and feel you expect of a high-end tubeless wheelset.

Usage: Adventure Road / Gravel / Cyclocross

FEATURES

Frequency Hub

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.

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

Need confidence your gravel wheels will offer a lightweight advantage but still last through seasons of riding? Proterra Light i23 and & i25 wheels provide the longterm reliability of a 3-cross lacing pattern with the weight savings of alloy nipples.

23mm inner rim width

Drop bar bikes with tires ranging from 32-40mm are best paired with a 23mm inner rim width, while a 25 inner rim width is best suited for the same bikes running 41-50mm tires. Choosing the correct inner rim width for the tires you ride will optimize the air volume and tire profile of your specific tire and rim combo.

HAND-BUILT

Proterra wheels are hand-built in our wheel building facility. 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.

PRODUCT TECHNOLOGY

TCS (Tubeless Compatible System) is our industry-leading tubeless rim/tire system designed to international ETRTO and ISO standards.

6069 is the perfect aluminum alloy for bicycle rims due to its high tensile and fatigue strength, minimal weight, and excellent anti-corrosion properties.

Spoke holes are drilled at an angle to match the natural spoke path between a rim and hub. Eliminates binding and lateral loading of the nipples to increase wheel durability.

Rim ends are hydraulically pressed over an extruded aluminum insert that matches the inner cavity of the rim and is further reinforced by industrial epoxy.

Installed between the rim and tubeless tape to prevent tape from sagging at each spoke hole and make tire inflation easier while also preventing puncture from a broken spoke.

Sloped rim valley allows the bead of the tire to easily and smoothly move into place during installation and inflation.

Internationally standardized to ensure rim and tire compatibility are as consistent and user-friendly as possible for both WTB’s products and those of our competitors.

Freehub ratchet system quickly alternates between two groups of three pawls each to provide quick engagement and trusted durability.

TCS TUBELESS COMPATIBLE

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.
