Transition Spire Alloy GX Complete Mountain Bike 2025

   6061 Aluminum Alloy Frame–        Known for its durability, strength, and ride quality, aluminum is real!

   Travel–        170mm Front / 170mm Rear

   Wheel Size–        29″

   Speed Balanced Geometry–        SBG ensures the bike maintains low speed agility, front wheel traction, and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds. With SBG, a slacker head tube angle is combined with an all new reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes. One of SBG’s greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed maneuvering as well as improved traction, control and confidence for any skill level of rider.

   GiddyUp 2.0HH Suspension–        Building upon the success of Transition’s original GiddyUp suspension design, the new GiddyUp 2.0HH system has been refined for the modern two-wheel cowboy delivering a slightly firmer feel for more efficient pedaling, as well as more progressive travel that provides that extra little bit of bottom-out support when needed.

   Geo Adjust Chip–        Change the attitude of the bike with a simple flip of a chip. High and Low settings give you two very usable geo settings to suit your riding style: High is comparable to most other companies’ low settings so there’s a high shred warning in effect!

   Pivot Technology–        Collet main pivot technology improves rear end stiffness and keeps hardware tight. Bearing shields prevent main pivot contamination from water.

   Frame Protection–        Fully integrated, flush-mounted rubber frame protection on the chainstay and downtube keep your bike rides quiet and your frame safe from damage.

   Dual Crown Fork Compatible–        This frame is fully dual crown compatible, for those wanting to dip their toes into the DH world.

   User Friendly Cable Routing–        To simplify maintenance and keep your bike noise free, the rear derailleur cable is routed through guide tubes in the front triangle and chainstay.

   Universal Derailleur Hanger–        SRAM’s Universal Derailleur Hanger is available at almost every bike shop, should something go wrong.

   Badass Bearings–        EnduroMAX suspension pivot specific bearings come in standard sizes that are readily available worldwide.

   Gear Accessory Mount–        An underside top-tube accessory mount allows you to carry a spare tube or other goodies safely on your frame.

   Water Bottle Compatibility–        Your water bottle is kept clean inside the front triangle so you can keep hydrated without worrying about mud making it to your mouth.

   Size Specific Chainstays–        The Patrol has two size specific chainstay lengths to provide balanced handling and rider weight distribution across the range of sizes.
