Bit specific, but does anyone know any good deals on reasonably light tubes at the moment, that absolutely definitely do not have removable valve cores? I had a very irritating situation on Sunday – squeezing in a ride when short of time, got a flat so swapped the tube.
The only problem was that the pump I had with me was a Lezyne with a threaded hose, and my spare was a removeable valve core tube… You can see where this is going! By the time I’d tried twice to inflate and remove the pump without dumping all the air, I had to curtail my ride and wait for someone else to pass with a pump I could actually use!
So, I’m thinking I will reboot my tubes arrangement, no removeable cores allowed!
