Ritchey Ultra 50th Anniversary Mountain Bicycle, Size M (17″)



1 in stock



The latest mountain bike, from one who started it all, Tom Ritchey.  If there’s one thing Tom knows, it’s dirt. When he first designed the Ultra he knew it would appeal to riders who demand specific ride characteristics and dirt slaying – and that was in the 1980s!

Good design withstands the test of time, and the latest iteration of the Ultra is a prime example. Like its predecessor from 30 years prior, the new Ultra occupies a unique ride space from cross-country riders to enduro riders.
