  • Transfers power to the ground immediately: the slightest force on the pedals travels through a 27-speed Shimano drivetrain and straight to the knobby tires
  • SR Suntour 100mm fork (with lockout) and powerful hydraulic disc brakes help you maintain control on descents and bumpy terrain
  • Hand-built aluminum alloy hardtail frame for classic simplicity
  • Custom formed and butted tubing balances stiffness and weight savings
  • Shimano 9-speed drivetrain offers 27 gears for any terrain
  • 27.5 wheels roll over obstacles and offer quick handling


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 Diamondback 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)!

Rated 5 out of 5 by from Sensational bike! Bravo Diamondback This bike is sensational from looks to bang for the buck performance. In person, it's absolutely stunning but more importantly it rides like a much more expensive bike. I can't believe how light it is. I'm 6'0" tall and the medium frame suits me quite well. I had REI switch out the stock seat (it's quite hard, thin and uncomfortable) for a split gel one and I signed up for the $20 rewards program so after tax I was well over $800 and I still feel like a got a great deal on a bike that will last many years. The tires are fabulous too btw.

Rated 5 out of 5 by from Great entry level mountain bike! I bought this bike after numerous hours of research. This bike has quality components for a great price. I have been on a couple of rides it shifts great, cruises nice, has great traction going down steep dirt hills, the hydraulic brakes are fabulous and it jumps like a dream.
