Mountain Frames

Heller Shagamaw Frame
The Heller Shagamaw is a 27.5+ carbon hardtail mountain bike frame that is primed to attack the trails. The sculpted carbon frame delivers stability and stiffness, with a modern, ready-for-anything geometry that encourages you to continually hunt out new gnar. The frame features a Boost 148mm rear axle and is optimized for a 1x drivetrain. Internal routing for cables, brake lines, and a dropper post keep the aesthetic clean. Designed around a 130mm-travel fork, the headtube is slack so you can attack the descents. Grab a Shagamaw and get to it!
Specialized Demo 8 Frameset
Tested and proven by Specialized's gravity team on the World Cup downhill circuit and ridden in freeride contests across the globe, Specialized's Demo 8 Frame will help you go faster and bigger than ever before. With super-slack geometry, 200mm of terrain-flattening travel, and a low top tube, the Demo delivers point-and-shoot handling, perfect for stomping big hits and railing the nastiest rock gardens. Controlling the rear end is Öhlin's revolutionary TTX coil-over shock. It boasts adjustable high- and low-speed rebound as well as high- and low-speed compression damping for the ultimate in tunability and ride quality. This burly platform was designed around the 650b wheelsize to maximize speed and control, so build it up with a big-travel fork and fat rubber for a World Cup-level DH rig.
Ritchey P-29er Frame
The P-29er marks the glorious return of the legendary Ritchey mountain bike. Tom Ritchey himself applied over 40 years of racing and building steel bikes into the P-29er. Like any Ritchey, it goes fast while remaining comfortable and durable with triple-butted Logic II steel tubing that balances sprint-winning stiffness with rough trail compliance. Built around a 100mm fork, the geometry was tweaked by Tom Ritchey and World Cup legends so it's equally at home on all-day epics or tight, technical singletrack. Big rides or small, the sliding rear dropouts let you choose between going singlespeed or running gears. And last but far from least, the instantly-recognizable tri-color fade is a tribute to the classic Ritchey P-series racing mountain bike from back in the day. It's a modern update to a piece of history.
Giant XTC Advanced SL 29er Frame
When every gram and pedal stroke mean the difference between the podium and going home empty-handed, Giant's World Cup XC racers run the full carbon XTC Advanced SL 29er Frame. A tapered head tube flows into the MegaDrive down tube, which in turn attaches to a huge bottom bracket to deliver laser-sharp handling and explosive acceleration. Add to that the confidence and control of 29-inch wheels and you can see why your competition sees the XTC as an unfair advantage. Don't go home empty handed.
Giant Glory Advanced Frameset
From world cup podiums to your local DH run. Give yourself the factory pro treatment with this lean, mean DH machine. This killer composite frameset has been developed and perfected over the years in an uncompromising quest to give Giant pros the fastest DH bike in the world. The latest version of the Glory Advanced breaks new ground in stiffness, weight and all-around performance. It features 200mm of fully active Maestro rear suspension on a superlight, stiff and strong composite mainframe. The frame geometry, engineered to optimize its 27.5 wheels, has helped deliver pros like Marcelo Gutierrez to World Cup podiums on the world’s toughest courses. It’s the lightest composite DH frame ever produced by Giant, and it’s hungry to win.
Specialized Stumpjumper Carbon 29 SS Frame
Simplify, simplify, simplify! Specialized's Stumpjumper Carbon 29 Singlespeed frame gives you exactly what you need to go fast and have fun, and nothing more. Built around a FACT 8m carbon frame that makes short work of trail vibrations while giving you the stiffness you need to attack the climbs, this svelte Stumpy is destined for sprinting success thanks to the Chisel carbon fork and stout tapered head tube. Lightweight so you spend more of your energy on forward momentum, the Stumpy singlespeed features sliding rear dropouts and is ready for all your favorite parts so you can build it into a simple, durable rig ready for the race course or your go-to after-work shred.
Ritchey P-650B Frame
This is the second version of a 650b mountain bike from Ritchey – Tom started to design his first in 1977. Even back then, Tom had a feeling that there was an advantage to the "middle" wheel size, but it took the rest of the cycling world three decades to figure it out: a 650b (or 27.5") wheel provides the bump-eating smoothness of a 29er, with the light, responsive feel of 26" wheels. Finally, the era of the 650b wheel is here. The P-650b is a close relative to the P-29er. Up front there's the proprietary forged-and-machined, gram-shaving integrated head tube featured on all new Ritchey frames. Forged socket dropouts and a new chainstay-mounted rear disc brake mount save a few more grams. And like every frame Ritchey makes, geometry and tubing is carefully fine-tuned by Tom, to bring the legendary balanced, nimble Ritchey feel to 27.5-inch wheels. - Weight: 2,028g for frame (L/17”) - Ritchey forged-and-machined 1.5” tapered head tube - Clearance for up to 2.25-inch tires - Fork: Designed for use with 100mm travel forks - Headset: Integrated 1.5” tapered - Upper bearing: 41.8mm OD / IS42/28.6 (S.H.I.S.) - Lower bearing: 52mm OD / IS52/40 (S.H.I.S.) - Bottom Bracket: 68mm English threaded - Rear spacing: 10x135 - Front derailleur: 28.6 low clamp – top or dual pull - Weight: 2178g / 4.8 lbs (M/17”, frame only)
Ritchey P-29er Frame
Tom Ritchey applied his 40 plus years of racing, designing and building steel mountain bikes into the P-29er. Like all Ritcheys, this bike is born to go fast without sacrificing comfort or durability. Heat-treated, triple-butted Ritchey Logic II tubing in their own unique butting profiles results in a frame that balances rough trail compliance with sprint-winning stiffness. The 29er-specific geometry was defined by the best way Tom Ritchey knows: countless hours of saddle time under Tom himself, World Cup legend Thomas Frischknect, and other racers. The result is nimble handling that captures the benefits of the big wheels, stable yet responsive, equally at home on all-day epics or tight, technical singletrack. • Ritchey forged-and-machined 1.5" tapered head tube • Fork: designed for use with 100mm travel forks • Weight: 2,150g (Size: L/19") • Bottom Bracket: 68mm English threaded
Heller Barghest Frame
Welcome to the world of no-fuss-sus! Heller's Barghest is a 27.5+ full-suspension trail tamer that’s itchin’ to shred right outta the box. The get-down-to-business, long and slack full carbon frame with a 130mm rear shock leaves little doubt about Barghest’s intentions. If the search for trail defines you, the Barghest frame is your perfect match.
Ritchey Timberwolf Frameset
Few can claim to have played a bigger role in the evolution of the mountain bike than Tom Ritchey. And he's still at it. The original Timberwolf debuted in 1984 as Tom's answer to the growing demand for a mountain bike that could handle more of anything. Reborn 30 years later, the Timberwolf is a hardtail incarnation of an all-mountain trail bike that can shred anything you throw at it. Designed around 650B wheels, the Timberwolf is agile and fluid whether bushwacking the mountainside or carving single track. It's the bike you won't be able to stop riding. - Optimized for 140mm-travel fork - Geometry measured at 105mm (140mm fork with 25% sag) - Designed for use with travel-adjustable forks - Forged and machined tapered head tube—lighter than standard integrated designs - Trail specific geometry to handle a more aggressive terrain and riding - Headset: Integrated 1.5" tapered - Upper bearing: 41.8mm OD / IS42/28.6 (S.H.I.S.) - Lower bearing: 52mm OD / IS52/40 (S.H.I.S.) - Rear dropout convertible between 142 x 12mm and Standard QR versions (ships with 142 x 12 + axle) - 30.9 seat tube with internal dropper post routing - Fits tires up to 2.4" - Weight: 2410g / 5.31 lbs (S/15", frame only)
Specialized Chisel Frame
Carbon isn't the only material that gets to have all the fun—the alloy Chisel frameset is the perfect combination of light overall weight, stiffness, durability, and alloy. Consider it the perfect start to your XC build. Traditional welding methods create frame joints by connecting tubes to cylinders, leaving the performance and security of the connection up to the skill of the welder. D'Aluisio (DSW), however, allows us to move the joint away from the area of the highest stress, making for a lighter frameset that's stiff, compliant, and incredibly strong—the optimal characteristics of a hardtail XC rig. So what does this mean for you? You'll be powering up climbs, shredding singletrack, and everything in between on a bike that has you questioning why alloy's gotten such a bad rap. And to further improve this feel, the Chisel also features our XC geometry, which took our previous XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked out front-end, the result of which is a tremendous increase in downhill stability, plus a wider range of fit. And just as importantly, this doesn't require any sacrifice of climbing proficiency. - Given its lightweight and ultra-stiff characteristics, M5 aluminum was the natural choice for the frame's construction. And when complemented with our speed-focused XC 29 Geometry, D'Aluisio Smartweld technology, and internal cable routing, you get a bike that compromises nothing in delivering explosive speed, confident handling, and hassle-free maintenance.
Giant Reign Advanced Frameset
The fastest, most confident Reign ever built. This enduro crusher features a lightweight composite frame that’s engineered for speed on rowdy terrain. Tested by Giant pros on extreme Enduro World Series terrain, it’s ready to rip. Updated and refined for the Giant Factory Off-Road enduro squad last year, the latest Reign Advanced features a longer, lower cockpit for fast, aggressive trail riding performance. It’s engineered with a lightweight, super-stiff Advanced-grade composite mainframe and ALUXX SL aluminum rear swingarm. The Maestro suspension system delivers 160mm of smooth, active travel with a trunnion mount shock and our Advanced Forged Composite upper rocker arm—which is lighter and stronger than the previous aluminum design. And it’s all designed around the performance benefits offered by 27.5 wheels, giving you the confidence and control to be fast and loose on hard-hammering terrain.
Giant Anthem Advanced Pro 29 Frameset
Speed meets stability. This superlight, composite XC flyer blends the most up-to-date Maestro suspension technology with totally reengineered 29er geometry. If XC racing is your game, this is the perfect partner for your podium quest. Handcrafted with a superlight Advanced-grade carbon frame, this XC flyer features 90mm of smooth rear suspension travel and 100mm up front. The new trunnion mount shock produces a lower leverage ratio for better pedaling and braking efficiency, and also allows for shorter chainstays to improve the bike’s climbing capabilities and agility. The Advanced Forged Composite upper rocker arm is lighter, stiffer and stronger than the previous aluminum version. And the combination of wider Boost hub spacing and a Giant WheelSystem gives you super strong and stiff wheels for confident, precise handling on XC terrain.
