Rocky Mountain has just released a new version of their Altitude trail bike. Rocky is using the term “trail bike” pretty liberally, with the latest Altitude sporting 150mm of rear travel and 160mm up front. Of course, compare that to what they label “enduro”: their Slayer Enduro bike with 160mm rear and 170mm front.

If you read my Slayer review, you can almost think of the new-and-improved Altitude as “Slayer light.” Much of the tech is the same, from Smoothwall carbon construction to single-sided bearing pivots, and more. However, unlike the two geometry positions available in the Slayer, the Altitude features classic Rocky Mountain Ride-9 geometry adjustment, with three primary geometry positions.

The Altitude is available in sizes ranging from extra small to extra large. In the size-medium, the head tube angle can be set to 65-degree, 65.6, and 66.1-degree options. The Rear Center (essentially the chainstay length) measures 425mm. Reach ranges from 430mm, to 436mm, to 441mm, depending on the Ride-9 setting. Wheelbase also varies slightly, from 1180mm, to 1179mm, to 1177mm. For more geometry information, be sure to check Rocky’s website.

Additional Technical Details from Rocky Mountain:

  • Increased anti-squat for better pedaling efficiency
  • 27.5” Wide Trail and 26+ compatible
  • Bearings at all pivots, including at lower shock mount (compatible with aftermarket shocks as well)
  • Blind pivots maximize heel clearance
  • Lighter, tooled rear axle
  • Improved cable management: large headtube ports, full shift housing, large downtube access port, and internal shift and brake housing within the front triangle
  • Future-proofed to be compatible with Di2, Fox Live, and a dropper post simultaneously
  • Seat-tube lengths have been adjusted to accommodate longer dropper posts at maximum insertion.
  • Chainstay and downtube protectors. *Due to production delays, the initial shipment of 2018 Altitudes will not ship with downtube protectors. They will be delivered to the shop where you purchased your Altitude as soon as they’re available.
  • Integrated “Spirit Guide” chainguide, with 2-bolt ISCG05
  • 1x only
