Whats the difference?
Whats the power difference?

Thanks

    Depends on the model.

    A good cable disc is better than a poor hydraulic.

    What is your budget?
  • Well the bike i'm hoping to buy comes with mechanicals on but i was wondering if it was worth changing them on purchase.
    The bike comes with Avid BB-5 disc.

    The avids are good. See how you get on with them.

    Have ridden with both, I found the mechanical discs good when new but mine needed new cables every 6 months or so, my hydros need bleeding every 12 months.

    They both have the same power e.g they will both lock the wheel but I think the Hydros are more modular giving a better feel.

    It also takes less effort to stop with hydros, you can lock a wheel with one finger using hydros but takes three to lock a cable.

    From my experiance the hydros are better, depends how deep your pockets are??

    I had a BB7 on my DMR and it was 1 finger power- no problem!

    I would of got a pair when I built the SS but they've gone in price- £55 each- just for calipers and discs is silly really.

    Got both. Avid BB7 and El Caminos.

    Both work well, mechs a bit heavier.

    Neither too much trouble.
  • ive only ever had cheap of both, and my cheap cables were, well i cant really say without offending the world, but suffice too say, they were not good. ive got tektro aigura comps (i think thats how they are spelt) and they are really good, and i guess they fall under the cheap catgegory at about 50 each

    so in summary, cheap hydros better than cheap cables, :D
  • If you're planning on doing much descending get hydros or you will die from arm pump.

    I did find years and years ago with a truly terrible set of cables discs that they would overheat quite drastically leading to no brakes at all though. When they overheated, the leer would pull back right to the bar with no effect :shock:

    That happens with road bikes too (without the heat) and it's due to crappy cable housing. IMHO there's nothing intrinsically 'special' about hydraulic brakes. I have seen them fail too! My friend was riding one of my personal bikes here in Tenerife & left without brakes on a DH section after 1) the front tyre wore through the front hydraulic hose, then within one hundred metres or so 2) the rear pads went. So we had to lend him one of my brakes and both limped home.

    I should add that after that incident I check the condition of my brakes more often.

    Just to go off-topic for a second, but do you need to remove the wheel and the pads to check condition, or can you gauge it from just looking through the caliper?

    hehe, thanks for fixing my typo in the quote!
    It must bahe been heat related issues (somehow) on the really really poor cable discs I had. It only happened when they were hot, and as soon as they'd cool down again they were ok.

    I've had Tektro IO mechanical discs and done LOTS of miles on them.

    They work really well when adjusted properly, but they need a fair amount very careful adjustment to work properly and are worse than useless when badly adjusted.

    I've gone back to V brakes, less power but less hassle too.

    Man you type too fast. And I thought my spelling had gone to sh¡t. :lol:
    Don't you just love that new google feature that auto-corrects spelling?
    Half the time I mis-spell stuff now. :lol:

    To be fair, the Auriga Comps are outrageously good for the money. Compare with Juicy 3s and you find cables come out better.

    Juicy 3s are great. Not had a problem with them.

    oh dear. not the 'avid juicy are censored '/'avid juicy are good' marmite argument again :roll:
  • joshtpjoshtp Posts: 4,329
    avid juicy are crao.

    :wink:
    no really, i hated mine. The Clarks SX skeletals i have noe are marvelouse though, and they arnt expensive. Iv also had Tektro Auriga comps, and still do i love them, wonderfull feel, great power, and easy to maintain.. good brakes.

    the clarks feel diferent, like "proper" expensive brakes, a lot like hope techs, and they have loads of adjustment... really light too and lots of power once set up (they are a fiddle to set up right)

    juicy's are good. i'm not saying they're the best, but there decent brakes and they work. imo/ime they look good, are light, have enough power, even with 160mm rotors and sintered pads, are reliable, aren't too hard to align.

    funny.. cuz in my experiance they are:

    not reliable, not much power, not that light, not very good looking, need big rotors and the pads dont last well, they are a fiddle to bleed, and have a weird, and i think unplesant feel.

    The thing is you an take 10 sets of the same brake and many of them will feel different. Jucies seem to be more variable than most hence some good good sets, others bad sets.

    Well who to believe? :wink:

    I've got J7s, preferred the feel of the Formulas and Elixirs I've tried though. But they have enough power for me, I've put a 180mm rotor on front to reduce overheating. They've worked absolutely fine since an initial setup issue, and bleeding is easy if you've got the kit.

    this is true i think, esp with cheaper brakes, high end stuff is often made to higher tolerences and with better materials, cheaper kit is a bit more variable.

    yep! :lol:
  • i replaced my aiguras today with elixir R's and even in the bedding in i can feel a difference. with my tektro is defiantely felt much more on/off, where as there seems to be alot more modulation on these ones :D
    not sure if they are worth abit over twice the price, but hey hoes, lovely none the less :)
