When Tom Ritchey first designed the Ultra frame, he specifically addressed riders who demanded specific riding characteristics as well as off-road capability that only he could deliver – and that was in the 1980s!

Good design is timeless and the latest generation of the Ritchey Ultra is a prime example. Like its predecessor from 30 years prior, it’s designed for both, cross-country riders who like to get their rocks off and enduro riders who also sometimes crave an all-mountain tour.

The Ultra is optimized for BOOST suspension forks with 120mm travel and equipped with the stable 148mm BOOST standard at the rear wheel. The frame is designed to accommodate 29″ or 27.5″ wheels and is extremely versatile. Whether using 29″ tires for a fast XC ride or 27.5″+ tires for the rough stuff, the Richtey Ultra frame is a rough and rugged trail master that doesn’t know when to quit.
