NEW! – CHUMBA USA – URSA MAJOR

 

IMG_0448

Our Amigos down at Chumba USA have been working on their fat-bike since before we met them at Interbike last year. Chumba introduced the 29+ Ursa last year at the big show in the desert and they also shared the news about their plans to bring a fat-bike to market called the Ursa Major. Since then, they’ve pioneered the first fat and plus bike races in their home state of Texas and put a team rider, Neil Beltchenko, on the podium of the Tour Divide race. While I was on the road, out west, Vince from Chumba, sent me the news that the Ursa Major was being released and was live on their web-site. If you like high quality steel fat-bikes made in the USA, you should continue reading. Vince told us that their fat-bike had been tested in the snow in Utah, Idaho, Wyoming, and Colorado and on the dirt in Colorado and throughout Texas. The UM is the product of multiple prototypes, long trail rides, races and about 10+ months of non-stop development and testing.
