Cantilever brake setup

Discussion in 'UK and Europe' started by [email protected], Mar 6, 2006.

  1. Ive got an older (late 90's) set of Dia Compe cantis on my S.Galaxy -
    but they havent got a tension adjustment screw - any advice on how I
    can set them up properly so I get equal spacing from the rim on each
    side ?

    Are these reasonable quality ? - Have been looking at the Suntour
    self-energising canti's at Sjs cycles, anyone had experience of these ?
    Do they warrant the high price tag ?

    Try and find what you want elsewhere. SJS prices are always high.

    Blimey - I didn't realise those were still made! A friend had them on a
    mountain bike years ago, and they did seem to work very well - he swore
    by them. As to warranting the high price tag, you might find a lower
    price tag if you look elsewhere. :)

    I bought a pair for our first tandem in an attempt to solve our braking
    problems (the problem was I didn't have much braking). "The best brakes you
    can buy, no matter how much money you spend". Hmm. They may have been
    marginally better than the low profile LX cantis they replaced. I then got a
    set of Magura HS66 brakes, and realised what good brakes actually felt
    like..

    Much as I hate cantis, in your situation I'd probably go for something like
    a set of Tektro Oryx cantis - 20 quid a pair.

    cheers,

    Are they like the old Suntour early 90's model, with a flat behind one of
    the calipers which can be held with a thin spanner whilst the brake fixing
    bolt is slackened off ?
    ( Just a random thought on where to look. )

    Monitor other sources, including Sjs cycles Ebay clearance shop. I don't
    think they merit the high "normal" prices.
    Also, a friend recently got a new On-one singlespeed, which had their new
    own-brand cantilevers, which look like they are well designed (too little
    conversation with friend to know if they *are* well designed).

    I've got around 3 pairs of canti brakes here.
    All used, but in good condition, these have been used on my cross bike.
    £5 for the lot if you want them.

    You use a cone spanner on the two flats behind the pivot bolt. Loosen
    the pivot bolt while gripping the flats with the cone spanner, rotate
    outwards to increase tension, tighten pivot bolt.

    My advice? They're horrible to set up - junk them and get some Tektro
    Oryx cantilevers, which use threaded V-brake pads rather than the awful
    plain-post design and have simple tension adjustment.

    By the way, the self-energising cantilevers are a waste of money. I had
    them on a Thorn and could never get any proper power from them, even
    with the lowest possible straddle wire setup. It's also a bad idea to
    have any brake with a self-servo effect on a bike.

    I have a pair of the Suntour SEs on the rear of my bike (only ever made
    for the back) and whilst I haven't properly fettled them yet, they
    don't seem any better than the Avid Shorties I had before - itself a
    supposedly high-class canti. I got them for a fiver when sjscycles were
    off-loading a load on ebay, so quite happy just to try them out. I dare
    say they could be improve by a bit more careful fettlling, but bear in
    mind back brakes are rather besides the point for serious stopping. I
    gather they are more recommended for tandems and v. heavy luggage. So,
    worth a go if sjs offload some more cheap but a bit dubious for
    full-price fifty quid or whatever, at least for a soly machine. Whilst
    I'm not familiar with your Dia-Compes they are a pukka make so are
    likely to be good. The bike is fairly modern and Dawes would presumably
    not have fitted crap onto their flagship bike. As a suggestion, should
    the hanger cable thingy (the bit that goes from one arm to the other)
    just self-adjust 'till they are symetrical - perhaps given the main
    cable a nudge in the right direction? This might or might not make
    sense.

    As an aside, I bought a 2nd pair to strip down to try and make them
    self-energising the other way round for the front; which might or might
    not be wise ! However I just can't get the guts out of them despite a
    lot of brute force. They are likely buggered now for original purpose
    or I'd have offered them to you.

    I got an unused pair for about fifteen quid on eBay a few years ago (not
    from SJSC), to put on my wife's bike as she wasn't happy with the
    stopping power her hands could manage with normal cantis. We found them
    powerful enough... BUT there's a tiny delay before they cut in. This is
    inevitable because of the way they're designed: as the block touches the
    rim it's dragged forwards, and it's not until that forward motion has
    started that the "self-energising" bit takes effect. So you get a brake
    that's initially weak but suddenly becomes very strong. She found that
    too off-putting so I got some new cheap Avids instead and they were
    fine. I think the SEs are really only suitable for tandems or very
    heavily loaded tourers.
