• I have a set of magura hs11 which I'm trying to fit to rear u brake bosses (I've seen it can be done). The clamps are positioned up side down, and they've been filled to within an inch of their life but the pads are still not low enough. If I can't get them to fit are there any other options? Are there any u brakes that have enough clearance for mudguards over a 26 * 2.1 tyre? This is pretty much the final piece of this project and it's doing my head in, so any ideas would be greatly appreciated
