Remedy 8 hits the sweet spot in all-mountain performance and value. A lightweight alloy frame, SRAM GX Eagle component spec, and a premium RockShox suspension package make it the ideal ride for sendy bois who want a ridiculously fun bike for whipping around on ridiculously fun trails. It's right for you if... You like getting rowdy on rough trails. One or both of your wheels leave the ground often, and you want an alloy bike that's tough enough to handle whatever you throw at it. You don't shy away from gnarly trails. Your bike shouldn't either. The tech you get A light and tough aluminum frame, an upgraded 160mm RockShox Super Deluxe fork with a plush DebonAir spring and Charger 2.1 RC damper that gives you more adjustment and control, and 150mm of rear travel with an exclusive RE:aktiv rear shock. Plus, a SRAM GX Eagle 12-speed drivetrain with leg-saving lower climbing gears, and Bontrager Line Comp 30 wheels. The final word It's our highest-end aluminum Remedy. The beefy alloy frame, 27.5" wheels, and premium suspension make it the perfect ride to dish out and stand up to some serious abuse on the trail. If you're measuring your rides in rad per dollar, you won't do better than Remedy 8. Why you'll love it - This is our best blend of performance and value in the Remedy family: an alloy frame with the same spec as much higher-end bikes makes this model a smokin' deal - 29er wheels are great for other people, but 27.5" wheels are livelier and more fun on rugged trails - It surfs down rough trails and conquers jumps with sure-footed confidence, then flies back to the top with its extra low 52-tooth climbing gear - Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride - Wider is more stable: Remedy has clearance for up to 27.5 x 2.8" tires

Bullet-proof, time-proven suspension at an unbeatable price. People say you have to spend a hell of a lot of cash to buy a full-suspension bike. Or at least a full-suspension bike that truly performs. They’re usually right. Usually. But not this time around. The Atroz proves them wrong with four inches of reliable coil-sprung rear suspension that nicely smooths out the trail. Since you’ll need to climb to the top of the mountain, we’ve also given the Atroz a 18-speed Shimano drivetrain, and when it’s time to head back down, you’ll find the Suntour XCM suspension fork and Tektro Aries mechanical disc brakes keep you firmly in control of the descents. - Hand-built 4-inch travel aluminum alloy full-suspension frame is super strong - Optimized single pivot with sealed cartridge bearings for smooth, durable performance - 18 gears courtesy of Shimano 2x9 drivetrain - SR Suntour XCM fork with 120mm of suspension travel - Tektro Aries mechanical disc brakes w/ 180/160mm rotors - 27.5” wheels offer quick handling

Slash 9.7 pairs fast-rolling 29er mountain bike wheels with long travel suspension to make one speed-hungry rig that's perfectly suited to both rowdy trail rides and enduro races. A full carbon frame, killer suspension package, and a solid parts spec means you're getting awesome performance at a ridiculous value, too. It's right for you if... You like ripping technical trails at warp speed and want a bike with insane descending prowess for the gnarliest trails and enduro races. You prioritize frame and suspension performance above all else, and want a durable drivetrain that won't break the bank. The tech you get A full OCLV Mountain Carbon frame with Mino Link adjustable geometry, a 170mm FOX Rhythm 36 Float EVOL fork with GRIP damper, and 160mm of rear travel with a FOX DPX2 shock that offers loads of adjustability and tuning options. Plus, a SRAM NX/GX Eagle 1x12 drivetrain and 4-piston hydraulic brakes. The final word Slash 9.7 gives you heaps of speed and courage for a shorter stack of cash. You're getting a full carbon frame, a solid parts group, and proven long travel suspension for performance where you'll notice it most. Why you'll love it - You'll fade before the FOX DPX2 shock does—it's built to help you squeeze the most out of long, gnarly descents - New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius - A sleek internal storage compartment gives you a versatile spot to stow tools and gear - We added a second down tube guard to better protect your frame from shuttle-related damage - Wider seat tube, wider dropper—the 34.9mm diameter post is stronger, more durable, and moves up and down faster

The Release 4C features the same bottomless-feeling rear suspension and deft handling as our aluminum Release models, but with an even lighter, stiffer chassis built from carbon fiber. It starts with our Level Link suspension system, which isolates chain forces from trail inputs, meaning the suspension doesn’t bob when you stomp on the pedals, yet becomes extremely plush on technical descents. For smooth bump-eating performance, the Release 4C is equipped with a Fox Float DPS EVOL LV rear shock and a 150mm travel Fox 36 Performance Float fork. SRAM’s NX Eagle 12-speed single-ring drivetrain provides consistent shifting and, thanks to its 50-tooth granny gear, makes short work of pesky climbs. SRAM G2 R brakes keep you slicing through the most technical lines all day long.

“Adventure bikes” are often plodding beasts of burden that sacrifice thrills in the pursuit of extra stability. Well, where’s the adventure in that? We went a different route entirely. By adding 2.8” wide, plus-size tires to our Level Link suspension, we’ve created a bike that absolutely rips on tight trails, but does so with the extra grip and control of a plus-size bike. Voila — adventure made awesome. We gave the Catch a slack-but-not-too-slack front end. We wanted control on fast descents, but we weren’t willing to give up maneuverability on tight trails. A Sram SX Eagle 12 speed drivetrain gives you the gearing to tackle any terrain and TRP Slate X2 hydraulic disc brakes bring this machine to a tidy stop. If you’re looking to tackle rough terrain and want the ultimate in control, without sacrificing the thrill of riding, the Catch is your bike.

Fuel EX 8 is the ideal trail bike for riders who want a versatile full suspension ripper that makes soul-crushing climbs less painful, but can also huck rowdy trails. It hits the sweet spot of value and performance in our mountain bike lineup by combining high-end parts with a stout but light alloy frame. It's right for you if... You're cool with your wheels leaving the ground, but you also like to go the distance on marathon singletrack sessions.

Reliable, affordable, and capable of nearly erasing roots and rocks. We love hardtails, but there's no denying the benefits of full-suspension mountain bikes—the added comfort and control. Unfortunately, dualies often add another thing: more dollar signs to the price tag. That's not the case here. The Atroz utilizes sealed cartridge bearings in an understated single-pivot design to deliver smooth, durable performance. The Atroz 2 ups the ante with Shimano hydraulic disc brakes, Suntour air-sprung rear suspension and an easy-to-operate single-ring drivetrain—features you usually find on bikes with a whole lot more dollar signs on their price tags.

With Supercaliber 9.7, you no longer have to choose between hardtail and full-suspension on race day. Every element of this bike is developed for fast capability, from the efficient IsoStrut shock to weight-saving, pivotless seat stays that cut down on trail chatter. A lightweight parts spec completes this XC-crushing machine. It's right for you if... You want one cross country race bike that works perfectly on all courses. You're looking for a light frame, cutting-edge suspension technology, and race-ready components, so you can churn out the fastest XC rides of your life. The tech you get An ultra-lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 100mm RockShox Reba RL fork, and Trek's exclusive, lightweight IsoStrut FOX Performance shock designed specifically for Supercaliber. Plus, a Shimano SLX/XT 1x12 drivetrain, and Bontrager Kovee Elite 30 carbon wheels with a 108-tooth rear hub for instant engagement. The final word Supercaliber is designed to crush cross country races, including the World Cup. It's fast, capable, efficient, and features IsoStrut—our game-changing integrated suspension technology. Why you'll love it - Supercaliber is a World Cup-worthy bike that's quick, capable of soaring through techy terrain, and nearly as light as a hardtail - Our exclusive IsoStrut shock provides tunable, damped suspension for a smooth and efficient ride - Pivotless seat stays save on weight and actively bend to help soak up trail chatter - Wider Kovee Elite 30 wheels provide better tire support so you can run lower pressure and get more traction - You'll never again have to wonder, "What's faster for this course, full suspension or hardtail?"

Built from a light yet tough aluminum frame, this all-mountain ripper features our much-lauded Level Link suspension design, which isolates chain forces from trail inputs. Or to employ less tech-geek speak, the suspension doesn’t bob when you stomp on the pedals, yet becomes extremely plush the moment your wheels start smacking roots and rocks.

Likewise, we outfitted this model with SRAM's SX Eagle 12-speed drivetrain—all the simplicity and durability of a single-ring drivetrain, with the low gearing you once needed a front derailleur to obtain.
