Lamp brackets made of something sensible?

  1. Hi,

    I'm on my second headlight bracket in less than 3 years, and that one's
    about to break:

    (You can see the crack where the longer upright meets the horizontal

    This is annoying - replacing the bracket is fiddly and time-consuming,
    it's a pain when your front light suddenly is hanging on only by its
    wires, and that bracket cost me €2.52 in March of 2014, which doesn't
    feel like good value.

    Are there any other options that might fit? A friend suggested one of

    Which is a solid-looking piece of cut, but will foul the bottom of brake

    Similarly, while I've not actually tried one of these:;product=25375;menu=1400,1410,1415;mid=0;pgc=0;orderby=2

    I don't think it'll go over the brake saddle when I engage the brakes.

    ....any ideas?

    Yes, they're crap. B+M changed to a rather more sturdy wire-based mount
    for their lamps, which is the second one you linked to.
    If you're very lucky it'll straddle the brake gubbins above, rather than
    going beneath. I'm not sure you'll be lucky though.

    I'm not sure I've got any helpful advice here. I mounted my front lamp
    on the fork on one bike, and the B+M worked on the tandem with the
    hydraulic brakes. And I do apparently still have a working one like your
    broken one on the bike with cantis.

    They do that.
    Eh? Ah, you mean "straddle" wire/cable/gizmo.
    Those B&M brackets seem to be generally the best solution, but might
    be a bit tight with your setup - you could bend it (reduce the bend to
    gain clearance off the wire, then bend the top bit forward to get
    clearance off the back of the lamp - you'd probably need to space it
    away from the fork with washers too).
    You could make your own (4/5/6mm stainless rod available in small
    quantities on eBay) or modify the broken one (weld/braze/solder gussets
    to the sides, or add a rod on each side that goes above the straddle

    Busch & Müller do one for cantilever brakes

    And as a B+M user, I really like those stainless brackets. Solid, no rust.

    This seems like it would go either side of Matthew's vertical brake
    My own light is on one of those and survives the abuse I give it.
    (It keeps getting knocked, on trains, mostly.)

  7. Yes. The weak point is the attachment to the frame, and that depends
    on your frame etc. Mine is on one of the old-fashioned steel rings that
    goes round the steering tube, so is pretty solid.

    Aye, and no cracking with fatigue even after several years, where it was
    a roughly bi-annual occurrence with the old ones made from some
    particularly brittle cheddar. Thum was shite.

    Why not think 'out of the box' and mount the light to your bars?

  10. I've got one of these brackets (which seems to be variously sold as SON,
    Thorn, or Jtek). Works fine, seems solid enough.
    It fits fine under my cantilever brakes. It has a long bolt, which
    sticks forward of the straddle cable. It probably needs about 1cm of
    height under the straddle cable. Hard to tell if you have enough space
    from your photo.
    You could extend the straddle cable, to move it up a bit, though that
    may affect how well your brakes work.

    It was me who recommended this to Matthew. He took a spare one of
    mine away to try it and told me that it definitely doesn't fit.

  12. That is why I decided to have nothing more to do with that trashy metal,
    aluminium, about 40 years ago! Since then, it has massively improved,
    as is now satisfactory for some uses, but is still unsatisfactory for
    many. And, of course, cheap and nasty aluminium castings are precisely
    as you describe.

  13. I have a spare one of those if you want to try it.

    The bike I thought it might fit is still using one of these:

    B+M do a "reinforced" version of the one you have (and I had - mine
    broke too), but I don't think it's much better (but haven't tried one):

    Similarly Schmidt do basically the same as yours but in stainless steel:
    (Stainless isn't necessarily any better when the problem is fatigue not
    corrosion, but given the quality of Schmidt's hub and lights, the bracket
    might be an improvement.)

    Stronger looking:

  15. Surprised they lasted that long! I once fitted a brand new one which
    lasted precisely one hundred of the BRITONS' miles before succumbing to
    fatigue. Which was decidedly inconvenient.

  16. There is also a version designed to fit under cantilever brakes, though
    it seems to be harder to find. They don't give the dimensions, so I'm
    not sure just how much space it needs, or how far forward it extends.
    Look for model 475DUPB. eg

    This is a useful summary of the B&M mounts, with details of what is
    compatible with different lights:

    Also this on the B&M site, though it seems to be somewhat incomplete:

    I currently have my (removable Cateye) light on my bars but I also use a
    bar bag from time to time. With the bag in place there's nowhere on the
    bars where the light doesn't simply illuminate the back of the bag.

    On my old bike I have a Minoura Space Grip which is ugly but effective
    and raises the light above the bag. On my new bike I haven't decided
    whether to uglify it or buy a new light. I haven't had to ride in the
    dark with with the bar bag yet.

  20. Well, not NECESSARILY, but in practice it will be. Few normal stainless
    steels are any worse than the better aluminiums, as far as fatigue goes,
    and most are as resistant to it as most mild steels. I very much doubt
    that you could buy a stainless steel that is as bad as the typical cheap
    cast aluminium.
