Frequently bought together:


The goal with Rocky's newly redesigned Altitude was to create a bike that could compete on today's racetracks while still being just as fun for those weekend warriors on the trails. 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, Rocky has introduced a wheelsize split on our medium Altitude frames. The Altitude is designed for 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.
