Sram Avid Bb7 Mechanical Disc Brakes For Road
Got these brakes on my recumbent bike. I wanted mechanical disc brakes, I didn't want a hydraulical system to leak during a vacation.
A broken cable is repaired easier. First impression was good. (summer, dry weather). After the first emergency stop (went well) I noticed that braking wasn't that good compared before the emergency stop.
Adjusted and everything went well. Then the fall began, and the rain began (Netherlands). I had to re-adjust the brakes two times a day, it seems that the brakes wear down faster when in a wet condition? When replacing the brake pads I noticed that the braking surface of the brakepads are very small. I can imagine that if the surface is bigger, braking works better and they don't wear down fast. At this moment i have my bike a year and a half, and i ordered the fourth pair of brake pads. (in the Netherlands they cost 38 Euro (front and back) that is about $51.
My advise is NOT to buy these very poor brakes. Got these brakes on my recumbent bike. I wanted mechanical disc brakes, I didn't want a hydraulical system to leak during a vacation.

Description of Avid BB7 Road Mechanical Disc Brake Caliper. Avid BB7 Road SL Mechanical Disc Brake Caliper. BB7 and SRAM Komfy disc brakes. Avid BB7 Road Disc Brake Caliper w/ G2. SRAM Avid BB7 Road S Front or Rear Disc Brake. Any bike nerd knows that these are the best of the mechanical disc brakes.
Be careful with the articulating washers when installing. I was happy to find that these work fine with my Shimano disks and levers. These feel definitely lighter in the hand than the Shimano m416s. Here is how I set them up: turn the pad adjuster all the way out to give lots of clearance, put on the adapter first and screw that tight to the frame you can put the caliper on the disk to make sure the orientation is right.
If the orientation is wrong the disk won't turn freely. Put the caliper on making sure that the articulating washers are put on correctly (they mirror each other on each side of the caliper.
Once the brake is on loosely tighten the pad adjuster as much as you can. Now leave those screws loose and hand actuate the brake holding it tight to the disk then cinch up the screws that hold calipers on. Let brakes open now and then back off the pad adjustment and see if the wheel spins freely. You can really move the install bolts and washers to get the perfect fit.
So far the brakes work fine for my city riding. So far the stopping power is good even going downhill. Novotni Everybody Ebook on this page.

I can't imagine you will be happy with a less functional caliper that saves only a few grams. Somebody on MTBR would probably be bragging somewhere if their mechanical calipers were a lot lighter than the BB7's. I'm sure you already know, but you can save a ton of weight on BB7's by installing titanium and aluminum hardware. I saved 28 grams in switching to titanium mounting bolts and aluminum pinch bolts front and rear. You can save a lot more with lightweight rotors and titanium rotor bolts. Also, a normal cable and housing system runs about 100g just for the rear. Run a lighter cable system.
