  • Diamondback Lux 27.5 women's mountain bike is quicker and lighter than 29ers, but offers the same benefits of large-diameter wheels—more speed and better traction
  • Compared to 26 in. wheels, larger-diameter wheels roll over obstacles more easily so you won't stall going uphill over roots and loose soil
  • Lightweight and strong aluminum frame has been specifically crafted to deliver a great fit for women; low stand-over height makes it easy to mount and dismount bike
  • SR Suntour XCT suspension fork supplies 80mm of travel for smoothing out rough trails; turnkey lockout offers increased performance on climbs
  • Shimano drivetrain features intuitive Shimano trigger shifters and responsive derailleurs to offer dependable shifts through the 24 gear combinations
  • WTB Wolverine Comp tires offer good all-around traction on the trail
  • Platform pedals don't require bike-specific shoes, making it easy to go from off-road to around town
  • Specs on the Diamondback Lux Sport 27.5 women's mountain bike are 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.

An oversize shipping charge of $75 applies to this item (plus regular shipping fees). Or ship it FREE to any REI store for pickup.
