Rocky Mountain ALTITUDE A70 Bike Coil of Duty Built for aggressive riders who refuse to back down, the Rocky Mountain Altitude A70 is the ultimate enduro weapon. Featuring a race-proven FORM(TM) Alloy frame and a high-performance Fox Factory suspension layout (170mm front / 160mm rear), this bike transforms brutal rock gardens into a smooth runway. Engineered with a low center of gravity and the signature RIDE adjustable geometry chip, you can instantly tune your ride for steep, technical descents or fast-rolling flow trails. Whether you choose to run a full 29er or a quick-cornering mullet setup, the precision shifting of its premium drivetrain ensures you are always in the right gear. Don't just survive the mountain-rule it. A threaded BB keeps service simple, and ISCG05 tabs are ready for a chain guide. Internal cable routing keeps the lines tidy. The frame also carries a 5-year warranty that transfers to a second owner. Suspension is all Fox Factory, with a 38 fork up front and a DHX2 coil shock out back. The 38's GRIP X2 damper gives you lots of room to tune how the front end feels. The coil shock comes with a spring matched to each frame size, and it stays smooth and planted over repeated hits. SRAM Eagle 90 Transmission shifting runs across a 10-52T cassette for plenty of range on long climbs. TRP DH-R EVO PRO brakes bring the stopping power you want on long, steep descents. A Maxxis Assegai up front and a Minion DHR II with a tough DD casing out back give you grip in rocky terrain. A Tranz X dropper with up to 230mm of travel on the XL gets the saddle low before you drop in.
