Disc Brake + Low Rider Rack + Mudguards

edited January 2011 in Workshop
I can see how to do Front Low Rider Rack (FL-1) + Disc Brake Caliper (Avid BB7 Road) but I can't see how to keep my mudguard stays. (At present the mudguard stay on the disc side is on a very long bolt sticking out so that it clears the calliper.

Back end is fine of course, as that is staying Canti.

Anyone got any pictures?

Edit:
I'm thinking: Mudguard Stays are pretty flexible, so just need to make sure they and the long bolt don't foul a bag

    Got it.

    The U-Bolts supplied by Blackburn don't fit my forks but they would end up in the wrong place anyway, so I need to create a bracket to use the braze on. And I can attach the mudguard stays to the rack to keep them short and out the way.

    Will post pictures once it's done

    Should really have shelled out for a Tubus or OMM. Meh.

    If you are planning on riding on any rough roads, or will be carrying much weight I would *very strongly* recommend NOT using a Blackburn FL-1 rack. It will break, the only questions are how soon, and into how many pieces; I have had several break, and have given up on them. Alu rear racks are a bit more reliable, but front racks really need to be steel as alu cannot survive the flexing it gets on the front.
  • get some universal adjustable Cateye brackets and mount them part way up the fork leg
    Recipe: shave legs sparingly, rub in embrocation and drizzle with freshly squeezed baby oil.

    My alloy low rider rack seems to have lasted well for the 18 years that it has been on the bike.

    If there was a steel option I might have taken it, but as it was I was struggling to find a design that works with Disc Brakes and wasn't insanely expensive.
    My bracket probably reduces the maximum weight a bit over what it would be if I was using the proper hardware as well.

    Where do they tend to break? Is it aluminium failure or is it weld failure?

    Do you have a picture? Curious to see how you made it.

    It's not finished yet.
    From Mid-November it's been too cold to go out to the garage much but had a chance a few days ago to get everything bolted up temporarily.
    I've still to finish wrecking the mud guards and fretting about how strong the B&Q Bracket is.

  • Yes, disc brakes are great until you want to fit mudguards and/or carriers.

    The mudguards wasn't a problem when I didn't have the lowriders.
    All I needed to do was put in a longer bolt with tubing over it and force the stays out wide, gave it about 5mm clearance over the caliper so slight increased rick of catching something on the front, but not anything that wouldn't be caught by my feet.

    The fotopic gallery http://hyperthenellyphant.fotopic.net/c1930052.html shows how I currently have it.
    All frame bolts will be replaced with hex key bolts.

    The rack is a fair bit off horizonal at this, so I may need to just bite the bullet and extend the spacing at the lower mid eyelet on the brake side so the frame can pass over the brake caliper and then hope to hell that the loop and bolt can take the strain.

    Not convinced if the strength at the top either, but if I can tilt it forwards I can drill the plate and put an M5 through and spaced directly into the upper eyelet.

    Not sure if having the loop on the front eyelets is going to be an issue either.

    I think the only real solution to this is to get me a decent length steel rod, and get my brother round with his MIG welder and built my own rack, unfortunately I was terrible at Structural Engineering.

    I'd save yourself the hassle and get an OMM rack. I have a Sherpa front rack (done many thousands of trouble free onroad/offroad miles with it), but I believe the lowrider racks will work with disc brakes as well.

    Btw when did you edit your thread? Weren't you calling disc brakes something weird?

    Don't know what else I would be calling a Disc Brake.

    The problems with the OMM are
    1) Price £80
    2) Finding somewhere selling the one for eyelets, I don't want to be mounting through the hub skewer and Canti-Bosses, particularly the Canti-bosses as I may have to refit Canti's in an emergency.

    I'm sure I'm not imaging it - instead of disc brake it was 'something' circle brake.

    Why can't you use the canto bosses and have a rack? I've used mine with v-brakes.

    I don't remember any particular problems fitting a Tubus Tara over the BB7s on my Peregrine last summer. It may have been simple because I use Berthoud stainless steel mudguards, which only have a single pair of stays.
    No photos unfortunately, or at least not without the panniers.

    Yeah, I can see how they fit easily enough as they don't have anything that crosses over the brake caliper, the problem is they are 60 quid plus.
    For something I don't have a clue if I will use more than once the £30 was bad enough.

    it was a result of a topic in the Crudcatcher. all is back to normal now.

    oh and OP people wondered why i mounted the caliper of the front of my fork :wink:

    Just had a look at that but too many posts to read properly.

    one of the Future Peeps changed the word filter (like the swear filter) to something or other.
