FAAAASSSTT! The Nano 40c is built for speed, and let’s just politely say it delivers. A 40mm, rounded profile and an elevated centerline provide enough volume for lower tire pressures and a smoother ride while still reducing drag and rolling resistance. This makes for an all out gravel destroyer that can still appease those clamoring for a truly big cyclocross tire. Winner? We think so. So does everybody else. Don't believe us? Just ask. Everybody's irrefutable favorite, 'nough said.

Byway is for days of endless hardpack exploration and gravel grinding while also providing noticeable efficiency on any pavement linking it all together. A swiftly smooth centerline is paired to a textured intermediate section that provides a seamless transition onto small outer knobs for unwavering traction in loose dirt and gravel. Prominent outer knobs also extend down the sidewall to provide an additional level of defense from roadside unpleasantries of all shapes and sizes. Byway 34 is an identical replacement to the previously named Exposure 34 tire. We renamed the tire to create a uniform naming structure where all tires are named according to the tread pattern. SG2 PUNCTURE PROTECTION: Most sizes of this tire are available with our all-new SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tire is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tires to become tougher as well. Please refer to the charts below to determine which versions are available with SG2. - Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. - Protected SG2 gravel tires feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tire. - SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall. FEATURES: - Smooth centerline for efficiency with diamond-shaped outer knobs for grip in the dirt. - High volume tire enables a comfortable ride. - Dual Compound rubber means a fast-rolling tire with great corning traction.

Race it hard or just head off the beaten path.

This TLR clincher with 120TPI nylon casing provides both performance, durability, and puncture protection when combined with the appropriate tubeless sealant.

The Knard is a tire that just makes sense. With its tightly-spaced, low-block tread pattern, it provides the perfect ratio of traction and low rolling resistance.
