WTB Proterra Light i25 650 Wheel

Proterra Light i25 wheels care for all your Road Plus adventure riders out there.

The extra traction and comfort of a high-volume 650 tyre is pretty nice, eh? Proterra Light i25 wheels feature an open-cavity profile to minimise weight and maximise efficiency as you get lost on backroad detours. Like all other Proterra wheels, the responsive 6-pawl freehub offers 3.7 degrees of reliable engagement whether you're cruising to work or have your frame bag bursting at the seams for an overnight adventure. Designed for Road Plus, because more volume is always more fun.

Technologies

TCS 2.0 - Sealant-based tubeless system that improves upon the foundation of WTB's legendary TCS (Tubeless Compatible System). The integral component of TCS 2.0 is the Solid Strip, which makes tubeless more robust and dependable than ever before.

ISO/ETRTO Compliant - Internationally standardised tyre bead and rim sizing. This ensures that tim and tyre compatibility are as consistent and user-friendly as possible for both WTB's products and those of theircompetitors.

On Ramp - WTB's On-Ramp bead construction provides a cosistent fit between rim and tyre for easy installation and inflation. On-Ramp also allows riders to easily pop the tyre bead to the centre of the rim valley before the tyre removal.

4D - Spoke holes are drilled at an angle that matches the natural spoke pathfrom rim to hub. Doing so eliminates binding and lateral loading of the nipples, which increases stability and extends the lifespan of the wheel.

Sleeved - Rim ends are joined together using an extruded aluminium insert that matches the inner cavity of the rim. Both ends of the rim are hydraulically pressed over the tight tolerances of the insert and then further reinforced by industrial epoxy.

Solid Strip - Durable strip that sits against the rim and prevents tubeless tape from sagging at the spoke holes, which makes it easier to inflate a tyre and protects from puncture in the case of a broken spoke. Tubeless tape is then installed over the Solid Strip.
