Ah, the aptly named Sherpa rear rack from Old Man Mountain. No matter what kind of bike you have (impractical or otherwise) this rack is likely to fit. 63cm criterium bike? No problem. Five inch travel full-suspension bike? Sure enough. Track bike? Yep, as long as your bike has a quick release on the rear this rack will fit.

The lack of a front stop means that longer stuff fits fine without having to totally hang off the back. The front rack mounts extend far forward and attach on the brake bosses or with clamps, for those deviant disc-only bikes.

Seriously, this thing is bombproof. The fine folks at Old Man Mountain rate the Sherpa for 40 pounds. That's a five gallon jug of water. That's a propane tank. That's some practical payloadin' proficiency, partner.
