The frame of the P-29er is built with Ritchey’s proprietary triple-butted Logic steel tubing. That combines with its modern XC geometry to deliver a breathtakingly balanced ride – beautifully mixing a snappy and responsive soul with a comfortable and predictable personality. The P-29er is the ultimate cross-country mountain bike. With its pedigree firmly rooted in the decades-deep lineage of its P-series predecessors that helped define the sport of mountain biking, this latest version of the P-29er is very much a modern machine with features demanded by today’s XC riders. It boasts BOOST spacing along with stealthy dropper post routing and an ultralight forged tapered headtube. It fits tires up to 2.3” and is built around a 100mm-travel fork. All of this comes together to enshrine the P-29er as a monument to the spirit of endless singletrack adventure.

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 only he could deliver- 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 looking to get rowdy and go big to 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. Designed to accommodate 29" or 27.5" wheels, the Ultra is highly versatile. 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. - Compatible with 27.5 x 2.8 and 29 x 2.4 tires - Internal routing for a dropper post - Boost 148x12 rear spacing
