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.
