Perfect compromise! Stopping power + cable simplicity!
By Nathaniel Allen
I've been using Avid mechanical disc brakes since nearly day one. I posted my original review back in November 2000 shortly after they were released, and have been riding them consistently since.]The Avid Mechs have gone through two redesigns since that time, and have gotten a few grams heavier and are now made of a 2-piece bolt-together construction, but I've used all three iterations and they're non-distinguishable in setup or operation.There is often a "cable vs. hydraulic" debate on mountain biking forums, and my answer is this: Avid's mechs are a heavier than the lightest hydraulic units (by a hundred grams or so), and require a bit more attention to set up and maintain (most hydros are self-adjusting and feature few setup options), but in turn you get fully tunable and reliable brake that can be fixed on the trail and doesn't rely on hydro fluid, bleeding or anything outer than basic wrenching to keep working drag-free.That's not to knock hydraulic brakes, as there are shining stars and dogs in that category. But it boils down to what you want to maintain at your house and in the field.Avid Mechs: + Offer multiple adjustments: Levers adjust modulation, ala Avid's "Speed Dial" and Shimano's "Servo Wave" adjustents. Offer "bite point" adjustment via the inboard pad knob (tool-less on-trail adjustment). Provide for additional modulation / reach adjustment via the outboard pad knob. Spring / lever resistance adjustment via the return spring set screw adjustment in the caliper body. + Easy to center without shims by Avid's "CPS" system consisting of concave/convex washers between the caliper body and the disc brake mount. + Anti-rub due to the manually adjustable pad adjustment knobs. + Very simple maintenance and on-the-trail cable replacement; no bleeding.The downsides are: - No auto adjustment: you must manually adjust for pad wear by dialing the pad adjustment knobs in every few hours of riding (depending, of course, on how much braking you've been doing). - The fact that there are so many adjustments, these are not a "install and forget" brake -- you must make yourself aware of all the different parameters the Avid mechs are capable of, and know how to tune them. They can be as "on/off" or "modulated" as you want them (especially with the various rotor sizes available), but they are not at all like most hydro units which offer zero or few adjustments and behave only as the designers intended them. - A bit of extra weight compared to the lighter hydro offerings.I've run Avid BBDB's / BB7's with everything from 160mm rotors on my wife's bike, to 203185 on my cargo bike, to 220mm rotors on my mountain tandem. Rotor compatibility is good, even with off-brand rotor/adapter sizes from Rohloff, Hayes, Hope and Formula. The calipers are the same, front or rear, the only difference being the adapter they're mounted to. These current "Graphite" editions mount directly to post-mount forks to fit 160mm rotors.Install is literally a 10 minute affair once you've got a handle on what needs to be done. Mine are all run with full length cable housing and I'd challenge anyone to a "lever squeeze test" to detect the difference between a well-setup Avid cable brake versus their choice of hydraulic.Again, this isn't to imply that these are better brakes than your choice of hydro units, but simply an equivalent option that doesn't involve hydraulic fluid and that gives an unmatched wealth of adjustment and tuning opportunities. Highly recommended, especially to the mechanically inclined.

A good solid mechanical disc brake
By Dave
I run the Avid BB7 brakes on my Thursday 26" BMX frame, front and rear. They're good solid brakes that do what brakes should. They stop the bike. Being mechanical (cable actuated) instead of hydraulic they're easy to install and work on. Best of all you can use any linear pull brake lever you like with them. I have small hands and often dislike the levers included with hydraulic brake kits.The BB7's have good modulation (easy to apply hard, soft, or in between) and work great in wet weather. After using three different lever sets with the BB7 brakes, the Avid Speed Dial 7 levers were oddly my least favorite. I found both the pricey Paul Love Levers and the inexpensive Tektro Tenera levers to be much more to my liking. Later I broke my left hand and ordered a ten dollar single right lever (from Rivendale) that pulls the rear brake wire just before pulling the front brake wire (yes, one lever, two brakes) and liked it so much that I haven't gone back. That's something I never could have done with a hydraulic setup.My final summation after using the BB7s for almost four years is that you can spend a ton of money on fancier brakes, but they are rarely better. The Avid BB7's are just as good, if not better than much more expensive hydraulic models I own. They do need to be adjusted during installation so get that done by someone who knows what they're doing or you probably won't be happy.

WOW What a difference!
By Brad
Upgraded from Tektro Novelas on my Nishiki Colorado, and WOW, what a stunning difference. I now have SO MUCH more modulation its unbelievable. I don't feel like I have to wrench all the way down on the levers to slow down now. With just a light tug on the levers, I can stop very swiftly without locking up. I am relatively new to mountain biking/trailing, however, I know enough to tell good brakes from bad. These BB7's are truly stunning, and offer a HUGE amount of adjustments (even tool-less at that.) Match with a good set of levers, and you have a top of the line 'mechanical' setup. My only regret is not going with a 203/185 setup. I instead went with a 160/160, I'll just get some different rotors when these go bad.
