    A friend told me he read about some v-brakes with extra long
    arms that can fit 3" tyres. Has anyone heard of these? I did
    a little search but couldn't find anything. If it's possible
    to rig up good quality v-brakes with my 3" Gazz I think I'll
    do it. If I need to I can always upgrade to Maguras. If I
    just get the single set of brake bosses attached to the
    frame that I'll eventually get made up, will I be able to
    upgrade to Maguras later on (assuming I had an exta-wide Magura-
    style brake booster made up)?

    I'd really like v-brakes for my muni. I like the idea of
    having something that's cheaper than hyrdo rim brakes and
    that's also simpler. I know that I can play around with v-
    brakes without having to learn more. I don't know anything
    about the Maguras and how to adjust them.

    If I do end up with suitable v-brakes I will get the same
    BBB brake pads that I have on my bike. They're really
    powerful and work reasonably well in the rain.

    Having now ridden down something steep on a muni with brakes
    (Tony M's), I think this v-brake setup will give me more
    than enough braking power and sensitivity.

    I found a picture of a Gazz with v-brakes around it on the
    German forum. I'd like something with much more
    clearance...I just thought I'd attach it though.

    Thanks, Andrew

    I have another question or two to ask before I go to bed.

    1. Are there many reasonably good quality v-brakes with a
    shape that's simple enough to allow me to have it
    extended by somebody who can weld? I was thinking it
    might be okay to just cut somewhere down the middle of
    the arm and add a little bit to it then weld it back
    together, maybe angled in towards the wheel slightly so
    you can add a spacer (to the place where the pads meet
    the brake arms) to give more side clearance but at the
    same time bring the top back in so it deosn't catch on
    things and generally get in the way. I'll attach a
    horribly crude diagram. My excuse is that I'm left
    handed but the mouse is on the right hand side.
    🙂

    2. Are most v-brakes made of a welding-friendly type of
    metal?

    Thanks, Andrew

    I made my own V brakes for my 24x3". I don't have my MUni here so I
    can't post a detailed picture but it was pretty simple. Here is a pic
    from Snowdon that shows it a bit:

    I put a bend in the arm just as you describe to increase the
    clearance around the tyre but make them miss my legs.

    Most V brakes are cast aluminium which is pretty hard to
    weld to. I made mine from some old, very cheap, steel
    cantilever brakes. The cheap pressed steel brakes are easy
    to weld to.

    There probably are some available in the shops somewhere for
    the knarley downhiller bikers using 3" tyres but I expect
    they will just as pricey as Maguras.
