Rocky Mountain Altitude A50 Bike 2021 Black/Brown

The Altitude will be our key platform for enduro racing and aggressive trail riding. Ridden by the Rocky Mountain Race Face Enduro Team, this bike is fast. Already race proven with Jesse’s win at the EWS in Zermatt, the redesigned Altitude is now more capable than ever.

The goal with the redesign was to create a bike that would be competitive on today’s racetracks while still being a ton of fun for those getting out on weekends. We might not all smash racetracks and stand on podiums like Jesse Melamed, but we can all relate to the feeling of committing to ride a little faster or hitting that feature you usually skip over. The Altitude has everything that you need to take your riding to the next level.

Looking at the needs of shorter riders vs. taller riders, we’ve introduced a wheelsize split on our medium Altitude frame. The Altitude is designed high speed descending and aggressive riding, which is why we’ve offered four frame sizes including both size small and medium with 27.5″ wheels.

SM – M: 27.5”

M – XL: 29”
