Rocky Mountain INSTINCT A50 Bike Trust Your Instinct on Every Line. If your local trails mix long climbs with fast, rooty descents, a do-it-all trail bike is the one to own. The Instinct A50 is made for exactly that kind of riding. By matching a rugged hydro FORM(TM) Alloy frame, full sealed cartridge bearings paired with 140mm of rear travel with a 150mm fork on 29" wheels this bike was engineered as the true "quiver killer". In the slackest setting, a size large gets a 65. 1-degree head angle that keeps the front end steady on steep, rough descents. A 76. 1-degree seat angle keeps you centered over the pedals when the trail tilts up. The RIDE-9 chip gives you nine geometry settings, and a two-position rear axle lets you change the chainstay length too. That makes it easy to set up for flowy singletrack one weekend and steeper terrain the next. The frame also carries a 5-year warranty that transfers to a second owner. Fox handles the suspension, with a 36 Float up front and a Float X shock out back. The 36's GRIP damper keeps the fork composed through roots and braking bumps. The shock gets a tune matched to each frame size. A Shimano SLX shifter and XT rear derailleur run a Deore 10-51T cassette, so there's a low gear for every climb. Shimano MT6120 4-piston brakes with 180mm rotors front and rear give you steady control on long descents. WTB rims come ready for tubeless with tape and valves included, and they wear Maxxis Minion DHF and DHR II tires. A Toonie dropper with size-specific travel gets the saddle out of the way before you drop in.
