The Transition Spur Carbon GX/Fox Complete Mountain Bike turns just pedaling along into speeding up. A slack short-travel ripper that's fully in the now, this is Transition's entry into the that hottest of bike types: call it modern, call it Downcountry, just don't call it underbiked. Lightweight and strong carbon, this frame takes the awesome GiddyUp suspension and removes a pivot and some hardware, utilizing a flex stay to save weight and make for a super poppy vibe on trail. Riders rave about the playfulness of this bike, with reviewers marveling at the DH capability of this shorter-travel trail bike. Your dream trail is calling!
All Carbon Construction – Full carbon frame made from premium Japanese Toray fiber with a tailored blend of high quality materials to create a balance of frame stiffness, strength, and impact toughness. A new molding process makes for sharper frame lines and tighter edge radius controls with less wasted material.
Giddyup Suspension Design – The GiddyUp suspension, featuring a one-piece flex stay rear triangle, is tuned to work correctly with inline style rear shocks and designed to provide a balanced feel with 120mm travel forks. Riders are able to add or remove volume spacers in the rear shock to suit their individual riding style and there is plenty of bottom out control for when things get rowdy. The Spur has 120mm of rear wheel travel when used with the supplied 190mm x 45mm stroke shock. It is also possible to install a shorter, 190mm x 37.5mm stroke shock, to reduce the rear wheel travel to 100mm if you are after a shorter travel experience.
Fox DPS Performance Elite – A lightweight chassis, EVOL air spring, and dual piston damper with 3-position switch create a pedal-friendly shock that soaks up the bumps and delivers pedal power to the ground with utmost efficiency.
Shock Adjustments – Air Spring Pressure / Lever Actuated Open, Medium, Firm Modes / Open Mode Adjust Tuning Range (1, 2, 3) / Rebound
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.
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.
Mega Seatpost Insertion – Dropper posts keep getting longer so Transition combined short seat tube lengths with mega seatpost insertion to help get your saddle completely out of the way.
Flex Stay – A flex stay system utilizes a carefully tuned carbon layup that removes pivot axles and bearings to save weight without compromising frame durability.
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.
Threaded Bottom Bracket – A standard 73mm threaded bottom bracket shell makes crankset maintenance hassle-free and prevents unwanted pressfit BB noises.
Water Bottle Mount
