I fitted SKS Blumels, then got it in the neck because they’re not long enough. I couldn’t find any longer ones, but I bought a spare set on eBay for a few quid, chopped one up and used my rivet gun to link the two bits together to get it much longer. Having ridden them, they’re much better and will keep the roadies happy.
I think I’m going to drill my rivets out and swap the additional section with the section on the second set that has the support wires fitted, so that the extension is properly supported and won’t flap about in the wind.
