Hi everyone. I have seen quite a few people using one or even two pieces of large diameter plastic pipe to store groundsheets, parasols etc fitted inside the main loop of bike racks. Last week I saw a guy in France with two of them but quite large diameters. They appear to have securable end pieces. Any idea on where I can get such things? I tried B&Q and Wickes but they either don't do large diameter pipe or don't have end fixings. Your advice is appreciated.
