TPU tubes offer many of the benefits of going tubeless; 
lighter/faster wheel-weight, superior road feel through 
the tyres, streamlined roadside repair kits... 
and they also retain the convenience of using tubes. 



But electric bike pumps generate heat which can damage 
plastic valve stems. Smooth plastic valve stems can also
make it difficult to attach your pump. 



Fumpa TPU tubes are optimised for use with electric 
bike pumps with textured metal valve 
stems to work perfectly 
with Fumpa pumps.
