  • Built around the Level Link suspension system, every part of this bike works to improve your performance
  • Patent-pending, short-link, 4-bar system results in Diamondback's best-pedaling mountain bike yet
  • With the rest of the bike designed to get the most out of the suspension, the Release One rides like it has much more travel than you would think at first look
  • Hydroformed aluminum frame delivers predictable, durable performance at a light weight
  • With a long top tube and short rear end, this bike's modern geometry makes it stable at speed yet balanced when dealing with technical trail sections
  • 150mm Fox Yari RC fork, SRAM drivetrain, 148mm thru-axle rear end and SRAM Level hydraulic brakes round out the parts for riders who earn their turns and seek speed
  • Boost 148x12mm RockShox® Maxle dropout
  • Diamondback Blanchard 28R tubeless-compatible wheels
  • Specs subject to change


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)!
