Fumpa 27.5" x 1.9/2.5 TPU MTB Tube
Lighter and faster wheel weight enhances ride performance, while providing excellent road feedback through the tires. Compact roadside repair kits remain practical, maintaining the ease of tube use. However, electric bike pumps produce heat that may harm plastic valve stems, and the smooth surface of these stems can complicate pump attachment.
Fumpa TPU tubes are optimised for use with electric bike pumps with textured metal valve stems to work perfectly with Fumpa pumps.
Available in four sizes to suit road, gravel, MTB and 29" tyres.
