I've never had to replace an inner tube that failed due to a manufacturing fault and I've bought some dirt cheap tubes over the years. The only flats I've suffered have been punctures through the tyre (pieces of flint, glass stone and thorn still remain in the tyre) and a blow out that happened as I had just finished improperly fitting one. I don't really know how to judge quality of tubes but anything the right size seems good enough.

I've reserved a few at a couple London stores near work and hopefully I'll be able to grab at least a couple as spares. Not had much luck with Halfords stock system on previous visits.

Good find. But very poor reviews. Don't want my spare tubes to puncture before I get home.

worth checking out these other reduced Boardman items as well.

thanks reserved 2 for a spare set for my 29inch hardtail MTB

Good find. But very poor reviews. Don't want my spare tubes to puncture before I get home.

Great price for a lightweight inner tube, but almost all of the reviews give them 1/5. Tempted, but not sure they're worth the risk.

Reserved the last 3 26" at my store, will do as a spares in the backpack with them being lightweight.

Get the continentals guys, save the heartache

good find op, heat added

Inner tubes make a big difference in terms of aero acruallym
