Tight enough tread spacing for high speed, drag-free onslaughts, yet blocky and tall enough to really dig in when it comes time to slam on the brakes. A rounded profile and staggered, supportive side knobs keep clamoring for traction even as the trail loses its camber. Most often used as a rear tire, the Trail Boss also keeps the front in check on hardpack trails. Want to go out and own it? Be the Trail Boss. Usage: XC / Trail / All Mountain Conditions: Dry to Damp / Hardpack to Loam - 27.5 x 2.25 Comp Tube-Type: 913g, DNA compound

Riding technical XC? The Barzo is the choice of the 2015 World Champion, as well as the winner of the BC Bike Race. How can such an aggressive XC tire roll so fast? The magic starts in the center tread, where we place an alternating ridge design and progressive sipe angles. Cornering duties are handled by the moto-style block knobs, laid out in a proven V-formation. The result is a tire that corners as fast as it rolls while still offering the protection of a full-depth tread. Rocks and roots? Check. World Championship? Check. - Aggressive XC tread for the most technical terrain - Medium spaced knobs for a range of terrain and conditions

Aggressive file tread, or super low-profile knob design? The Terreno bridges the gap between file treads and traditional all-conditions treads. The key to this is the unique, angled "fish scale" design, that allows the center tread to roll extremely fast, yet offer traction when loaded in cornering and braking. Add the transitional-height mid and side tread, and the Terreno Dry transitions as smoothly as it rolls. From gravel grinding to medium conditions cross racing, the Terreno Dry offers consistent performance. - Center "scales" are ramped, providing a fast-rolling leading edge yet sharp and effective braking and cornering edges - Graphene compound technology

GRAVEL Cannonball is a go-to gravel race tire for normal conditions. The tread pattern features a directional, tight-knit center tread that sheds dirt and debris to decrease rolling resistance, and side knobs for effective cornering traction. Cannonball is built for all-around gravel riders and racers. HOW IT WORKS - Center lugs are raised and ramped for rolling efficiency; the diamond-shaped lugs squeeze in for grip as they contact dirt, then back out to shed debris. - Transitions lugs are spaced out and vary in height to boost traction. - L-shaped side lugs dig in for grip while braking through corners, but roll quickly when off the brakes.

FAT PLUS Coronado is a plus-sized tire that increases ground clearance, stability and momentum, and floatation. Its mild and open center tread works with slightly more-aggressive side knobs for traction and efficiency in varied terrain. Coronado is an excellent choice for riders who venture onto the most rugged roads and trails. HOW IT WORKS - Center lugs feature a square-edge paddle design for maximum traction when pedaling and braking in loose terrain. - Transition lugs are tall and spaced out to shed loose debris; perpendicular siping enhances traction when turning. - Side lugs are large to dig in on turns and especially soft surfaces; a braking-shovel shape maintains control while braking in turns.

OFF-ROAD Ehline is an ideal tire for modern XC trails: fast-rolling without compromising cornering performance. Ehline’s tread pattern and casing provide more traction and durability than traditional XC tires, making it a great choice for riders who take on increasingly aggressive and challenging terrain. HOW IT WORKS - Center lugs are short, tightly-spaced, and ramped to roll quickly; perpendicular siping provides grip during both braking and acceleration. - Transition lugs are ramped to roll quickly and spaced out to shed mud; horseshoe-shaped siping allows lugs to conform to the terrain to maintain traction during braking. - Side lugs are taller and staggered, with parallel siping to enhance grip while leaning into a turn.

OFF-ROAD Honcho is a high-performance tire designed for trail bikes. The tread pattern features tall, aggressive, and angular lugs that provides ample traction on loose and uneven terrain. It’s perfect for riders who tackle rocky, rooty trails. HOW IT WORKS - Center lugs closely and evenly spaced for a fast-rolling feel; enclosed siping improves traction while accelerating and braking. - Transition lugs are tall and spaced out to shed mud; horseshoe siping conforms to the trail and maintains braking traction. - Side lugs are staggered with parallel siping for grip while leaning through corners, and a braking shovel shape boosts traction when stopping.

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 Designed with the unknown in mind, the Rutland takes the guess work out of selecting the right tire for the ride. Ramped, tightly spaced center lugs reduce rolling resistance while larger, more spaced-out shoulder and transition lugs provide grip in loose conditions. HOW IT WORKS - Center lugs are large and widely spaced for braking and acceleration grip, and ramped to lower rolling resistance. - Transition lugs are spaced out to shed mud; siping conforms to the road surface for increased traction in corners. - Side lugs are staggered to provide traction in more aggressive turns and on loose surfaces.

OFF-ROAD The Warwick is our progressive trail tire that’s versatile enough to handle stout XC terrain or enduro courses. Stepped center lugs and firm rubber reduce rolling resistance so you can carry speed. In corners and loose terrain, the large-multi-faceted lugs, open transition area, and softer rubber bite into the trail surface so you can throw yourself into turns with gusto. Two tire compound options (Fast and Grip) let you tailor your tire choice for the way you ride. Warwick balances control and speed for a fast, fun ride experience on many trail types. HOW IT WORKS - Center lugs are angular and have stepped front faces for rolling efficiency; a flat face on the back of the center lugs boosts braking traction. - The open transition area makes space for the shoulder and center lugs to dig into loose trails or grapple onto roots and rocks when climbing, and helps reduce rolling resistance. - Side lugs are large and multi-faceted for consistent, supportive cornering on rocky, rooty, and loose trails.

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 - Recommended rim width: 23 – 30mm
