Good mid-range tube with Presta valve
on 17 June 2013
This is a mid-priced inner tube for road/racing cycle tyres 700mm in diameter and with a skinny profile for minimum rolling resistance and higher speeds.
The tube is fitted with a Presta valve which will allow tube inflation to >100psi pressure, and the design makes over-inflation impossible. The tube is synthetic rubber rather than natural latex and claimed by the manufacturer to be "...extremely airtight! The butyl rubber compound prevents pressure loss and fewer occasions to inflate".
Weight of the tube is a modest 104g so no problem to carry as a spare in your saddle bag. The only caution is that the design of Presta valves means they can be rather delicate and occasionally break, necessitating the inconvenience of a tube-change - so always handle carefully and use the screw-on dust cap to protect them.
