As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It's shown people the light of how high-volume, large-diameter tires can vastly improve the ride experience. It's also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension-corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29 x 3" tires

The trunnion mount shock has a longer stroke (62.5mm compared to 60mm on the previous gene - Adjustable enduro geometry Flip chip technology lets you switch between three settings depending on the terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm bottom bracket drop (size - Rear wheel options Riders can choose either the stock 29-inch rear wheel or switch to 27.5. The larger 29-inch option improves stability and roll-over capabilities, while 27.5 delivers a more agile, snappier feel. It's a quick and easy way to adjust the bike's handling and TECHS & FEATURES: - ADVANCED COMPOSITE TECHNOLOGY Giant's High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. - ADVANCED FORGED COMPOSITE TECHNOLOGY A state-of-the-art high-pressure molding process is used to produce complex-shaped carbon fiber components that are lighter, stiffer and stronger than similar components made from aluminum. This technology is used in critical performance parts such as Maestro Suspension rocker links. - MAESTRO SUSPENSION TECHNOLOGY Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail. - OVERDRIVE Giant's original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system's oversized headset bearings (1 1/4" lower and 1 1/8" upper for road, 1 1/2" lower and 1 1/8" upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness. - TUBELESS SYSTEM Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits. - FLIP CHIP - MAESTRO The flip chip allows riders to quickly adjust the geometry of their Maestro-equipped mountain bike to better suit how and where they ride. It lets riders change the headtube/seattube angles and bottom bracket height via eccentric (offset, two-position) hardware located on the upper rocker arm.

From early pioneers like Rob Warner in the 1990s to world champions including Myles Rockwell (2000) and Danny Hart (2011), many of downhill racing's greatest legends have flown the flag for Giant over the years. This special-edition frameset celebrates that heritage with vintage Giant colors and design. Beneath the stunning paint lies cutting-edge DH design and technology including full-composite construction, an all-new Maestro suspension system, and ultra adjustability to tackle different types of DH terrain. KEY PERFORMANCE FACTORS RACE-READY SUSPENSION A new Maestro rear suspension system, developed over several seasons of World Cup racing with Giant engineers and pro athletes, features 200mm of smooth, active travel for race-winning speed. The rear suspension is paired with a 203mm travel fork, providing superior confidence and control on the most extreme DH racetracks and trails. ULTRA ADJUSTABLE Three flip chips provide unprecedented adjustability. First, a three-position Maestro flip chip lets you dial in frame geometry for your riding style and terrain. Next, a new headset flip chip adjusts reach so you can easily achieve perfect positioning. And finally, a rear dropout flip chip lets you adjust the overall wheelbase and handling characteristics. REAR WHEEL OPTIONS Choose either a 29-inch or 27.5-inch rear wheel. Frameset can be built with a mixed wheel "mullet" setup that many racers prefer with the smaller rear wheel creating a snappy, agile feel and increased saddle-to-tire clearance in the rear. For those who favor the rollover speed and stability of two 29-inch wheels, you can easily swap out the rear wheel. HIGHLIGHTS: Thoroughly reengineered from the ground up, the new Glory Advanced features a lightweight, super strong composite frame, 200mm of Maestro rear suspension (with a 203mm fork up front), and multiple flip chips to dial in geometry, rear wheel size, fit and positioning. The stock setup is a mixed-wheel configuration with a 29-inch front and 27.5-inch rear, striking a perfect balance of roll-over speed and maneuverability. Riders also have the option to switch to a 29-inch rear wheel using a simple two-position flip chip on the rear dropout. The legend is back. ADVANCED COMPOSITE Mainframe and rear swingarm crafted with high-performance grade raw carbon fiber and custom resin that's custom made in Giant's own composite factory. Handcrafted monocoque construction makes it extremely lightweight, stiff and compliant. MAESTRO SUSPENSION Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail. ADVANCED FORGED COMPOSITE A state-of-the-art high-pressure molding process is used to produce the hybrid aluminum/carbon fiber upper rocker link that's lighter, stiffer and stronger than pure aluminum. ADJUSTABLE DH GEOMETRY Frame geometry can be adjusted between three settings to match riding style and terrain. You can select a 61.6, 62 or 62.3-degree head angle and corresponding 78.4, 78.8, or 79.1-degree seat tube angle, resulting in a 13, 8 or 3mm bottom bracket drop (size M/L). ADJUSTABLE WHEELBASE A flip chip on the rear dropout can be set to a Long or Short position to adjust the wheelbase and rear-center measurement. The Short position results in quicker, more agile handling for tight, technical terrain. The Long position extends the wheelbase for added stability on faster trails with longer straightaways and high-speed cornering. REACH ADJUST A three-position flip chip at the headset lets riders quickly dial in cockpit dimensions and geometry. This modular system has two positioning chips that can be removed and swapped to achieve a Short (-5mm), Mid (0mm) or Long (+5mm) reach and fine-tune the bike's handling and rider positioning. REAR WHEEL OPTIONS Riders can choose either a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. The larger 29-inch option improves stability and roll-over capabilities, while the 27.5 option delivers a more agile, snappier feel. It's a quick and easy change to adjust the bike's handling and feel. MEGADRIVE A massive rectangular down tube and oversized top tube provide superior lateral and torsional steering precision. The precisely engineered, rectangular shaped down tube yields unprecedented steering and pedaling stiffness.

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Your BMX Bike All Grown Up Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It's just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a single speed mountain bike.
