I have been looking for some panniers so I can dispense with my rucksack and after much shopping around, plumped for a pair of Basil Mara XL from Halfords, not least because they were cheap at £22.99 (less 10% via Cycling UK membership) and 27 reviews on Halfords website led to an average rating of 4.6/5. They have plenty of space and after picking them up, and fitting them outside the shop, I nipped over the road to Tesco and got a shed load of shopping which I carried home in them. The problem I have with them is that when pedalling, my heels hit the front bottom corner of the panniers. I put them on my other bike which has a slightly bigger frame, and although it's not as bad, it still happens now and again. I have tried putting them further back on the rack, but can't get rid of the problem. Although a couple of reviewers mention this, most don't. I am thinking of either returning them, or perhaps trying to get a haberdasher to tuck the bottom corner in a bit, and sewing an extra velcro strap to make the fastening more tight. Has anyone else had similar experiences with these or other panniers. and if so, have you found a solution that I might be able to try?
