Chumba Ursa major titanium fat bike (1)

After their rebirth at Interbike last year, Chumba Cycles is settling into their new Austin, TX home. Led by new owner Aaron Foreman, the company has gotten back to their made in the USA roots. Gone are the slacked out, long travel DH machines only to be replaced by a new generation of Chumba bikes that focus more on adventure and pushing past personal limits. That means some very interesting steel hard tails, and in this case, their newest bike will be clad in titanium.

As their first full sized fat bike, the URSA Major will be sold alongside the URSA Minor – their  midfat 29+ option. While many of the details are still shrouded in mystery, we did get a few tidbits straight from Chumba. You’ll have to wait for the actual release of the bike, but read on for a little tease…

Following the same built to last mantra as the rest of their fleet, the new URSA Major will be made from metal – titanium as mentioned. The frame will utilize an aggressively sloped top  tube with an additional support brace from the seat tube to offer excellent top tube clearance. If you’ve ever stepped off a fat bike into soft snow, you know this can be pretty important. So far we know the bike will have a 197mm thru axle rear spacing which likely points to clearance for 5″ tires on 100mm rims.

Chumba will be selling two models of the Major with a rigid Backcountry version shipped with a frame bag, and a trail model based on the 100mm RockShox Bluto. As soon as the geometry is finalized, they will start taking preorders. In addition to the bike, Chumba is also helping to get a Texas fat bike race series off the ground and will be hosting the first race. For more detailed shots of the bike head over to their facebook or chumbausa.com where they are also running a promo on their STELLA 29 framesets with a FOX 32 CTD and Cane Creek 110 Headset, offering 20% off with code STELLA.

Erinsikink,

One is what you just bought. The other is what the industry is saying you need to buy, in order to be happy.
