Rocky Mountain INSTINCT C50 Bike 2026Do-Everything. Trail Weapon. If your local trail rides are a mix of long climbs with steep, technical descent. The Instinct C50 is a carbon trail bike made for exactly that kind of riding. Rocky Mountain has blended elite climbing efficiency with fearless downhill composure. Its frame pairs 145mm of rear travel with a 160mm fork on 29" wheels. In the slackest setting, a 63. 5-degree head angle keeps the front end calm when the trail gets steep. A 76. 5-degree seat angle keeps you centered over the pedals on the way back up. The adjustable flip chip RIDE-4 System allows for geometry settings to be changed, and a two-position rear axle lets you dial in the chainstay length too. Built-in Penalty Box 2. 0 storage gives you a spot for trail essentials so they're not riding in your pack. The frame also carries a 5-year warranty that transfers to a second owner. Up front, a Rock Shox Lyrik Select with the Charger RC damper stays composed through roots and rock gardens. The Super Deluxe Select shock out back gets a tune matched to each frame size. SRAM Maven 4-piston brakes give you strong, steady stopping on long descents. WTB rims wear Maxxis Minion DHF and DHR II tires, and both are ready to run tubeless. A Tranz X dropper with up to 230mm of travel on the XL gets the saddle low before you drop in. ISCG05 tabs are there if you want to add a chain guide for rowdier terrain. The drivetrain is SRAM Eagle 90 Transmission, and its 10-52T cassette gives you a low gear for the steepest pitches.
