Oh so close, but no cigar for me.
Pretty simple to fit, but the bike I was fitting themto (my Peacemaker fixed) wasn't playing ball. Firstly, they attach with cable ties round the brake bolt, and I don't have one on the back. Simple solution, extra cable tie through the hole for the brake bolt, so sorted.
These 'guards are designed for low clearance, even stating in the video instructions that you might have to drop a wheel in order to fit it in, it can squeeze into THAT small a clearance. Except my front forks appear to have even less clearance than that. The rubbing was immense, and if I adjusted the stays so that it was only just rubbing the tail stuck out so far the toe overlap was hideous. I took off the tail extension, and still any turn beyond a slight bend and my geet would catch the guard.
All of which is to say that these are really well designed, and I think would be reasonably sturdy, though on a daily commuter I think they'd get knocked about a bit too much - I reckon they'd get misaligned quite easily.
So it's back to Raceblades for me, which don't give quite the same coverage (the new Roadracer rear 'guard especially is completely full length), but which are quicker to fit and don't foul the front wheel...
