    BB7 Road Vs. Mountain

    Okay, so here's my dillemma. I recently purchased a Dawes roundhouse 2500 bike, and also recieved a single Avid BB7 Road brake system for my birthday (don't ask why only one), So I decided to install it in the rear brake slot and connected it to my Tektro Eclipse levers. At first I figured there was not much difference between the road and mountain version of the brakes, but after breaking them in a bit, I started looking around, and I am starting to think that the road versions aren't such a good idea for my bike and brake system. Can anyone set me straight, should I try and switch to mountain versions, or should I keep the road versions in?

    You should use the Mtn. version, braking performance will increase greatly. The other alternative is to use road levers to match the pull ratio of the road calipers.

    Alright, on a scale of 1 to 10, how critical is it that I replace them?

    depends- how badly do you want to brake well? Now without the sarcasm- i seriously suggest you get the mt versions

    I have the road version of the BB5 on my freeride and I really start to be afraid of trail with them, but they still work good as temporary fix. I will replace them with a BB7 MTB version anytime now. But I think as long as you also have good brake in the front, your good to go. I will use the BB5 as my rear brake on my trail bike with a 203mm rotor and I will try to let you know how I roll.

    And I think JensonUSA still have the 185mm BB7 MTB on sale at $45 right now... Include a caliper, rotor, pads, bolts, adaptors and a small torx key to assemble everything.

    I did the same

    Hep, what is the manufacturing date on the caliper and rotor ? Mine is April 14, 2011, for the 2010 model

    although technically they will tell you not to use that little tool to actually install the rotors and use a torque wrench instead (just saying)

    Dredging this thread up.....

    I have BB7 roads on my Salsa La Cruz, they are good but not the most powerful, would switching to mtb BB7s be a possible/beneficial/practical upgrade? Currently have Shimano 105 levers/shifters.

    I use this bike for commuting/adventure/rainy day rides on a mix of roads, fire roads and relatively buff singletrack

    Also wondering if switching/replacing the pads/rotors would be a worthwhile improvement?

    Thanks in advance for the input.

    No, your braking would be worse with the mtn BB7, and likely non-existent because the levers will not pull enough cable.

    I use BB7 road calipers with various Shimano STI levers (Sora, 105, Ultegra, Dura Ace) and they all are very powerful.

    Good straight cable routing and preferably full length housing maximizes power. Mostly use Avid G2 rotors and EBC Gold pads.

    The trouble with common sense is it is no longer common

    Thanks for the reply, that is what I was figuring that the level pull would not be compatible.

    I think fresh cables/full housing would be a good move for me and probably a fresh set of pads.

    Thanks again!

    gotta get the pads adjusted right. once you do that, they work great. i used them on a loaded tour and I'm 250 lbs and the bike had another 50 or so loaded on it plus the bike was about 35lbs!

    How are we supposed to know if YOU need a brake change?
