Ah apologies, I was referring to the dry bag! If memory serves alpkit do the duel ended one in a 13 and a 20? Just wondered which you had for rough sizing... I ride quite narrow drops so less width and more girth (ooph) is probably more what I’m after..
I have the 13 litre one. You can pack it so full that it barely fits between the hoods, but as it is it seems to work. I haven’t ridden like this mind you...
I was thinking Glasgow this weekend (7/8) and Dorset next weekend (14/15)
