OK, the good news is that mine has arrived today.
The bad news that I am having trouble fitting it to my bike. The following is going to show up my ignorance of these things, but here goes anyway...
The light comes with a fork crown mounting bracket which needs to sit between the front brake and the fork being pinned by the bolt that normally attaches the brake to the fork. The problem I have is that this bolt is currently exactly the correct length to make contact with the threaded recessed nut that sits 'in' the rear side of the fork. If I add the 5mm or so of the mounting bracket, the bolt can no longer reach. Worse still, the ring that sits between the fork and frame would interfere with the mounting bracket unless I added about 4mm of spacers to hold the bracket away from the frame. There are currently no spacers in my setup to remove to give me any extra length. So the bolt is upwards of 1cm short of its ideal length if I want to use the supplied mounting bracket.
So what options do I have? Do front brakes come with different bolt lengths? Would it be too dangerous to remove the gnarled nut that holds the spring in place? Are there alternative mounting brackets that are used to avoid this problem? Googling doesn't turn up anything obvious to me other than scary things like drilling into forks.
Apologies for the awkward explanation, but it strikes me this must be quite a common problem and I would have thought one that have an obvious solution I have missed.
BTW, the light itself looks great so far.
Jo - in case you haven't sorted it yet, this page may help:
http://www.sjscycles.co.uk/brake-spares-other-dept356_pg1/#page=If you scroll down to the Wheels Manufacturing bolts GBP3.99 each, you'll see they are the usual brake bolt nut but in different longer lengths. They reach further through the fork crown to get to the brake bolt, which is not so far into the fork crown once you've put the lamp bracket on. They don't have a thread in the back though, so you can't fasten your mudguard bracket on the back of the fork crown, but then I'm guessing you don't want to.to
One point to note, if you've not already discovered it - depending on exactly which type of headset you have fitted, the lamp bracket can sometimes foul the bottom race cap if you try and fit it right up hard against the fork crown. You may need to pack it out a bit, which will mean the brake bolt will need to be even longer still.
Apologies if I'm pointing out the bleeding obvious!
