Challenge MTB ONE Team Edition Tubular Tire, 27.5 x 2.0, Black

Handmade Mountain Bike Race Tubular

The MTB ONE is a handmade mountain bike tubular with a very supple 300 TPI casing and a fast, grippy tread.

It's a race weapon for top-level cross-country. Whether you race XC on tubular wheels or want the lightest, most supple setup, it's a rare option. Tubulars are sewn-up tires that glue or tape onto a dedicated tubular rim, so check your wheels before you buy.

Challenge is a family-run company with Italian roots. It makes its tubulars and handmade clinchers by hand in its own factory in Thailand, close to where its natural rubber and latex come from, and its classic treads like the Criterium, Paris-Roubaix and Grifo trace back to the old Clément molds.
