REEBdonkadonk Shred, Pinion Gearbox Reliability
We took the same proven REEBdonkadonk platform that’s been shredding ColoRADo snow packed singletrack for years and took it up a notch. No more snow packed and frozen drivetrain. No more chain lube. Just perfect, reliable shifting with no hassle.
Pinion’s light, compact, and carefree gearbox is perfectly suited to the rigors of fat biking. It’s sealed from the elements, works great in cold conditions, and can handle way more torque than your legs can dish out. Throw in belt drive reliability from Gates Carbon Drive for the most maintenance free drivetrain available.
The Pinion REEBdonkadonk frame uses our made in house, custom chainstay yoke for big tire clearance and the shortest possible chainstay length. The beefy 44mm headtube and 1 3/4“ downtube are paired with a 67 degree HT angle and 31.6mm seat tube to fit modern dropper seatposts. Each and every frame is Barn Built, hand cut, hand welded, and hand powder coated in-house in Lyons, CO.
The build spec listed below is only an example of the possibilities. We’ve built quite a few Pinion equipped REEBs and no two are the same. If you like the build here, go ahead and click buy now below, you won’t regret it! if you’d like something a little different, email firstname.lastname@example.org with your component requests and we’ll work up a custom quote.
