Maneuverable. Lightweight When GT started building bikes, it was all about hitting the trails with your buddies, not just gearing up for a long race weekend. We never lost touch with those roots, so we've developed the Helion for the XC rider who wants to go hard with friends and sometimes get rewarded with a cold beer, instead of another medal. Stable, maneuverable, and lightweight, the all-new GT Helion is the ultimate blend of past, present, and future fun.RockShox Reba RLT Suspension Fork The RockShox Reba RLT fork comes with 120mm of travel, providing a silky smooth performance and also maintaining traction, Remote lock out allowing you climb easier with a rigid fork and descend with pleasure to hit all the rock-infested trails with the full travel.Shimano XT Drivetrain The Shimano drivetrain is the perfect combination of performance and durability, with the XT shadow plus rear derailleur to enhance gear indexing and to reduce chain slap, the Race Face Aeffect chainset with its CNC machined arms help to reduce weight but maintain the strength. These both will ensure the classic Shimano reliable shifting and performance Shimano SLX Hydraulic Brakes Shimano SLX hydraulic disc brakes with a 180mm center lock rotor on the front and the rear, offering high stopping power for tracks that you might not normally hit up.Race Face Finishing Kit Finishing kit is by Race Face, set up with 6061 aluminum handlebars, stem, and seat post.
