ALL-ROAD From minimum maintenance to decaying pavement, rolling hills to near vertical climbs, Rampart was made for riders who want the freedom to pick their own path no matter what the road looks like. These tires were designed and inspired by our experiences riding and racing courses with varying conditions. HOW IT WORKS - Center tread is smooth and fast-rolling for straight-line speed; thicker center tread and durable casing lasts longer even on harsh surfaces. - Transition and side lugs consist of 3-2-1 siping for traction on all road surfaces.

GRAVEL Whether your route covers rough roads or fast gravel, or even both in the same day, Washburn is built for the job. Its center slick provides awesome rolling efficiency on pavement and packed dirt, while the shoulder lugs take over in the turns, digging in for confidence in loose corners. HOW IT WORKS - Center tread is smooth to minimize rolling resistance and maximize speed. - Transition lugs are tightly spaced to provide progressive initial cornering traction. - Side lugs are spaced out to dig in while cornering and when riding over loose surfaces.

When you’re out on a ride the last thing you want is to be limited by your tires in any way. Our ExtraTerrestrial Tires were designed to let you ride without limits by simply following the only tenets we have for tire design: they’re high volume and they kick ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off-road touring tire that shines on hardpack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET Tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between tread blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won’t bog you down on smooth or hard surfaces. - Folding bead - Casing: 60 TPI

MICHELIN's StarGrip tires have a fascinating history. MICHELIN engineers were charged with designing shoes that could “adhere even to a stainless steel plate with an oily surface.” The tire guys saw the shoe's tread and this tire was born. The tread features star-shaped ridges extending in all directions, and like the shoes, it cuts through water, snow and mud for an outstanding grip. The tire's compound is similar to those used for winter car tires, so it remains flexible in the cold to provide unrivaled traction on wet, slippery roads and trails. In addition, there's a high-density nylon layer beneath the tread for excellent puncture resistance. So regardless of the weather, you'll have tires that can handle the ride.

This race-day-specific weapon has raised the bar on tire technology. The Corsa Speed uses a proprietary Graphene compound, which is then paired with an ultra-fine Corespun-T casing.

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.

Speaking for itself, Raddler is the radder version of our famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centerline with get-rad traction of chunky outer knobs. Let’s call it a semi-slick, but one designed to increase confidence while you’re pushing the limits of gravel. Raddler is an excellent choice for loose terrain where traction takes priority, but efficiency is never far behind. Lean it over, take the inside line, brake late, and stay pinned with the Raddler. FEATURES: - Short-knob center tread cuts down on rolling resistance while still providing enough bite for out-of-the-saddle traction. - Center and intermediate knobs on the Raddler are slightly taller than those of the original Riddler, thereby increasing tire lifespan without negatively affecting rolling efficiency. - Tall, toothy outer lugs ensure your favorite gravel descent doesn't unravel in the final corner. - Single-ply, 60tpi casing provides dependable protection at a minimal weight. - Available with black or tan sidewalls in 40mm and 44mm widths. - All Raddler tires are TCS tubeless compatible.
