Maintenance Free Adventure Bikepacking

The Pinion Sam’s Pants is an Adventure bike in the very truest form.  Load it down, leave the chain lube at home, and don’t worry if you don’t have time to wash it.  We build this bike to just keep going.

The Pinion Sam’s Pants features the 29” x 2.2” tire clearance of our standard Sam’s Pants model and adds a Pinion gearbox and Gates Carbon Drive Belt for reliability that is next to nothing.  Cinq Shift:R Shifters provide smooth and consistent shifting for the Pinion 12 speed gearbox.

The Pinion Sam’s Pants frame gets the same treatment as our standard Sam’s Pants.  A 44mm headtube for a solid front end, a third set of bottle bosses on the downtube for extra water and gear, and a 31.6mm seat tube to fit a broad selection of modern dropper seatposts.  We also add Paragon Sliding dropouts to the Pinion version for belt tensioning.  All of our expertly manufactured, confidence inspiring lightweight steel frames are welded in Lyons, CO.

Go now, go anywhere

**note- Due to the lack of availability of shifters, we cannot complete builds as spec’d at this time and have no estimated date.  We can, however, build a Pinion Sam’s Pants by substituting a rotary shifter.   Please email for more details.
