    Avid BB7 improves with speed dial levers?

    Hi,

    I have a set of Avid BB7 with Avid FR5 levers on my Kona Unit.

    Love the ease of setup and adjustment of the BB7, but I can't get the lever to respond the way I like.
    When the rear brake is set up correct, the lever can be pulled almost against the handlebar.

    If I would "upgrade" to speed dial levers, would it be possible to adjust the cable pull ratio so I will get a lot less travel in lever?

    Is it worth to do the upgrade? And what levers to choose (SD7, SD SL or SD Ultimate <- way to expensive for me)?

    Thanks.

    If you can't get the pads closer to the rotor without them rubbing and the brake lever can almost be pulled to the handlebar, I'd say you've probably got a warped rotor.

    If I set pads one clock further they will rub.
    Will check how true the rotor is tonight.

    So replacing the levers might not be an upgrade?

    Thanks.

    there are a lot of people who like the speed dials,... personally, I found they just "soften" the feel and to get a real constant and firm response with them I had them set all the way out. ended up just going back the the 5's for levers..

    if you are pulling to the bars you have something setup wrong,... bent rotor, loose cable, pads not clicked in, leaning caliper, bad/weak cables.... just to name a few.
    Going to try and bring Trail Tire TV back. go take a look... http://trailtiretv.blogspot.com/

    Fiddle a bit around with trueing the rotor and it does feel a lot firmer at the moment.

    Unfortunatly I cant take it to the trails until next saturday. So will have to wait till then to see if it helped.

    Thanks

    Re: Avid BB7 improves with speed dial levers?

    Went on the trails this morning. Must say that they where better initially.
    After a couple of miles the lever could be pulled much further then before ( but not till the bar)

    Ordered some new cables and trying to get a bargain on some SD levers. If that doesn't work, I'll be upgrading to hydros

    If I upgrade it will be XT or XTR.
    Probably XT since XTR is too expensive

    Sounds like your cable is slipping. Make sure your cable anchor bolt is torqued to spec.

    As for the levers:
    I am still running the BB7s from off my '09 Unit (which I broke) with SD7 levers that I got a few years ago and they work great. Definitely recommend the upgrade.

    Have you considered having a shop look at your brakes? When set up properly, BB7's are a very adjustable, responsive and powerful brake.

    Use the barrel adjuster on the brake itself to add tension to the cable. Turn it out until the brake arm just begins to move, then continue to setup the brakes as described in the owner's manual.

    What you are describing as your issue is almost certainly caused by low cable tension. After you've done the above, you can decide if you would like the additional modulation that the SD-7 provides. The Ultimates do not have any significant difference besides weight and a bearing in the pivot versus a bushing.

    I must say that I have little complaints about the power of the brakes.

    Its the way the brakes respond. that is not the way I like it.

    What cable housing are you using?

    One of the quickest things to check for is do you have a full run of brake cable housing from front to rear? Avid days this is the first thing that should be addresed.
    After that it's the type if housing you are using. There are two types, brake and der. Der is often referred to as non compressionless housing, as it does not compress. It comes in 4mm and 5mm thickness. If you do 4mm make sure you get the metal ferruals, not the cheap plastic kind. Most 5 mm almost allways uses metal ferruals.
    Then make sure rotor isn't warped, that's an easy visual inspection.
    After that follow SRAMs avid set up guide, it's the best way to go. I'm using like ten year old avids with xt' brake levers and once I followed the above advice it was throw me over the handle bars stopping power

    Standard from a 2012 Kona Unit. No brand or type to be seen on cable housing
