TPU tubes

A new range of inner tubes specifically designed for use with Fumpa pumps. 

Made from an ultralight, super-tough, heat-resistant TPU material with textured metal valve stems for great nozzle grip without risk of damage from the heat generated by all electric bike pumps.

TPU tubes offer weight and ride quality benefits of tubeless wheel set-ups without the downsides of messy sealants, difficult roadside repairs and trouble seating tyre beads.
