  • Pinion C1.12 gearbox-driven drivetrain provides a wide 12-gear range and boasts virtually maintenance-free operation that won't leave you stranded in the backcountry
  • Dynamo power-generating front hub and The Plug USB charging system powers your devices anywhere, anytime

  • SRAM Guide R dual-piston hydraulic disc brakes and 200mm front / 180mm rear rotors for powerful, reliable stopping power

  • Internal cable routing keeps the frame and cockpit area clean and free of cable clutter
  • Race Face ARC 40 rims and Schwalbe 2.8 wide tires offer unlimited traction and the ability to plow through whatever the trail throws at you
  • While 27.5+ x 2.8 wide tires come stock, Roket frame accommodates both 27.5+ and 29er wheel and tire combos with Boost hub spacing (29er wheels not included)

All bicycles sold at REI include a free warranty tune-up. New bikes go through a normal break-in period, after which readjustment is important for longevity and performance. Bring your new bike in to your local REI for its free tune-up within 20 hours of use or 6 months from purchase, whichever comes first. Contact your nearest REI bike shop to schedule this important service.


When you purchase your GHOST-brand bike on, have it shipped to any REI store where it will be ready for pick up fully assembled (and you'll avoid the home-delivery oversize shipping charge)!
