Ritchey Heritage Tom Ritchey knows bikes. 40 years of designing, building and riding them has made him an expert, and the Ultra MTB frameset is a testament to this experience. First designed in the 1908’s, the Ultra has stood the test of time and undergone upgrades to move with the times. Much like its predecessor, the modern Ultra is perfect for those mountain bikers wanting an all-rounder. Perfect for XC riders who want to go big, and enduro riders chasing some all-mountain shredding. The Great All-Rounder Optimised to work with a 120mm travel fork and the super stable Boost 148mm hub width, the Ultra will accommodate either 27.5” or 29” wheels. Throw on some 29s for some trail-smashing XC riding, or saddle up some 27.5+ for some serious no-holds-barred shredding. The Ultra is a rough and rugged trail master that doesn’t know when to quit.
