I picked up a near new Dawes Galaxy that had been in storage for 8 years. I'm super excited to get on a tour. I have both Lands End to John O'Groats and London to Paris locked in:)

The tires are marked Schwalbe Marathon 32 - 622 (28 x 15/8 x 1 1/4 - 700 x 32c) hs308. Tube markings have always confused me, and I'm sure it gets asked here all the time.

What tube should I be looking at here in the UK as a spare?

Will this one be OK?

Yes, the number most usually listed is 700x32, so anything with that in the range will be the right size. You can even get away with slightly bigger or smaller tubes in a pinch.

The ones you linked to should be fine, or try these from Schwalbe. Some people recommend Schwalbe for reliable tubes as well as tyres.

Note valves: It might matter whether you currently have Schrader (like a car tyre) or Presta valves. If you have presta, the Schrader tube valves might not fit through the hole in the rim. Probably simplest to get the same kind.

700x32 isn't in that link you sent. Did you mean 700 x 28/42? –  square_eyes Feb 24 at 21:04
    
Well, 32 is between 28 and 42, so well within the range. –  James Bradbury Feb 25 at 10:56
    
Ah OK thanks. It's all so unnecessarily complicated:) –  square_eyes Feb 25 at 14:58
    
I found these which should be as good a price as any. Although I don't think the picture matches the description. The box says 18 and the details say 28. –  square_eyes Feb 25 at 15:17
