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 capabilities only he could deliver—and that was back 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, catering to cross-country riders looking to get rowdy and go big, as well as enduro riders lusting for some all-mountain shredding.
Designed around a 120mm travel fork and super-stable Boost 148 spacing, most of the fun is in the wheels. The Ultra is highly versatile, accommodating either 29" or 27.5" wheels. Throw on some 29s for trail-smashing XC riding, or saddle up some 27.5+ for serious, no-holds-barred shredding. The Ultra is a rough and rugged trail master that doesn’t know when to quit.
