TPU Tubes #schrader 2"): 0 - 20 psiFumpa TPU tubes are optimised for use with electric bike pumps with threaded, heat resistant metal valve stems which work perfectly with Fumpa, other electric bike pumps, as well as traditional floor and hand pumps. TPU tubes offer many of the benefits of going tubeless: lighter faster wheel weight, puncture and pinch flat resistance, superior road feel through the tyres, streamlined roadside repair kits but they retain the convenience of using tubes.
