Inner Tubes for 27.5x1.6" tyre

[hoppym27]

Ive bought some 27.5x1.5" Schwalbe marathons to put on my wifes MTB, but I seem to be struggling to find inner tube to fit..plenty of 27.5 tubes around but the smallest Ive found start the range at 1.7"...any ideas anyone?

Yes, unless you want new wheels

Where did the bike come from - how about asking them?

Go back to Evans and ask them. It seems a weird size for sure. Maybe the 1.75" version would fit ok

Or buy a dozen from Merlin while you can!

If you get stuck finding the right sized Schraeder tube, Specialized (I think it's Specialized) presta tubes feature a lock ring with a ridge on it that locates in a Schraeder sized hole. Alternatively you can by inserts to pad out the Schraeder hole to presta size.
