We are going to the Dales come August and I was looking for a Tank bag,they tell you the capacity in litres but not in.. ins/mm.

I am looking for a small/medium tank bag side pockets etc so does anyone own one simular, that can give me any sizes etc as ** litre? doen't mean much to me..

Thanks for any help

Best I can do as I can't find my tape measure is say that the two I have both have a base measurement about half an inch longer and wider than Bike magazine.  Capacity then is more governed by extra height rather than too much extra width or length as these are more difficult to accomodate.  

Best thing you can do is get yourself into a bike shop and look at what they have.

Thanks lads Ive just been viewing the bags (ooh' er) and I think Ive found one, for those in the know its a 14 ltre none exspander map pocket n' all the bells n' whistles..

Thanks for the help..
