The Speedster is designed for rolling speed and minimal drag on hard-pack or paved terrain. The honeycomb center tread provides virtually zero rolling resistance and unbelievable tread life. This feature also gives you excellent traction in dry or wet conditions. Large diamond shaped side knobs provide the grip you need in corners, while the tread knobs get smaller towards the center for the ultimate speed and traction. And with its balloon-style structure, you’ll feel like you’re floating on air.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
