The Proterra Light i27 wheel is ideal for daily use on trails. It features a 27mm internal rim width, offering optimal air volume and tire profile for tires ranging from 2.3" to 2.5". The open rim profile reduces weight where it is not needed. The versatile six-tooth hub provides 5° engagement, ideal for technical climbs.

Proterra rims pair with high-quality hubs, enhancing the performance of this lightweight and reliable wheelset. Frequency hubs feature a low-friction 6-tooth design, providing instant 5° engagement. A durable nylon disk protects the tubeless tape from pressure, ensuring a smooth connection between tire and rim, facilitating tire installation.

The TCS (Tubeless Compatible System) design ensures compatibility with tubeless tires and meets international ETRTO standards. TCS components offer reduced weight, increased grip, and minimize punctures. All Proterra wheels come tubeless-ready and include TCS tubeless tape and valves made from black alloy.

Proterra rims are made from 6069 aluminum alloy, offering optimal strength, with a bead-peen finish for lasting appearance. Extensive testing has shown that other 6000 series alloys are less impact-resistant, while 7000 series tend to increase flat surfaces.

Proterra wheels provide the compliance expected on the first ride and the durability required on every ride.
