Surly Pack Rat

The Pack Rat rolls on 26” wheels in the smaller sizes and 650b wheels in the larger ones. Smaller diameter wheels keep the weight of the load lower than a 700c wheel would, thereby improving handling and ride feel. Pack Rat’s fork also includes some handy internal routing for generator hubs so you can safely ride off into the night.

Dedicated commuters, credit card tourers, those who enjoy the occasional sub-24 campout, and sweaty back people looking to leave their backpack behind need look no further than the Pack Rat.
