Chevin Cycles used to do three for a tenner, but no more it seems. Any deals out there? Cheers.
Not an offer as such, just damn cheap 🙂
Why not use 26er tubes? Just pump them up a bit ,fit in tyre and you're away.
Simples.

Save a few quid on a four pack of extra light tubes.
Using 26" tubes is not a great idea. I used to do this but had one blow up, shredded to bits, effin great big bang. I suspect if it was a 29er tube it would have slowely deflated, where the stretched 26" tubes simply went off like a suicide bomber.
I use the superlight tubes above, whip out the valve, add 50ml or so of stans sealant. This gives me thorn protection at no extra weight over a normal 29er tube
Hope this helps.
Pedalhead, I seem to have a surplus at present. PM me 😀
