Wheel decal close-up, mounted on the Chumba Rastro. Also, there isn't a Fox 36 on this. Really, there isn't... trust me (more than 5mm of fork and tire clearance achieved, so if there were a Fox 36 on this it'd be just fine).

A close-up, and a reminder to grease your splines.

By Patrick Reed, President of Dirt Components. 4/23/2017
I love my fat bikes. And I've ridden them everywhere fun in the United States, Pisgah National Forest in NC, Captain Ahab in Moab, the infamous Thumper trail in my neighborhood, Birkiebeiner in WI, Crested Butte's nordic and downhill ski trails, Angel Fire in NM, and Apex in beautiful Golden, Colorado, among others that will always be in my heart. I'll always enjoy that grip and control of a 4"+ tire on all of these foreign terrains I've been lucky enough to get to ride over the last three years. But something happened about this time last year while attending the Fruita Fat Tire Festival: I fell in love with a plus bike.

Puppy love, a spring fling, the grass looked greener. This bike wanted to play. And the trails we were riding? 18 Road was tamed, and later on, after moving the party out to Utah, riding Hymasa and Upper Ahab became an exciting revelation that there needs to be more than one type of bike in my stable.

Chumba USA's brand new homegrown Rastro. Made by hand right outside of Austin and close to Pace Bend Park, this wheelie-inspiring huck machine will have you smiling and laughing like a maniac your entire ride. The angles are right, the front suspension is big, the stoke is high. And when you liven this beast up with lightweight, stiff shoes, you've got yourself a shred-monster. XT group of course, call them for other options.

Chumba icon and logo. This bike begs to be ridden hard.
