Strengths:    Cheaper than hydraulics and, easier to service.

Weaknesses:    In order to keep these brakes working properly, the cables and housing have to be
cleaned or replaced fairly often which starts to negate the difference.


Bottom Line:   
As only one side of the caliper actually moves, the rotor bends
to meet the fixed side of the caliper before any braking occurs. This isn't
the recipe for quick, responsive braking especially if you're a Clydesdale!
I'm sticking to hydraulics (Magura).

Strengths:    Ease of adjustment, reliability when braking, quiet, simple build design

Weaknesses:    braking can be a bit squishy depending on how they are adjusted

Bottom Line:   
These are great starter disc brakes or for those who want a good value mechanical brake system. If you are thinking about BB5 or BB7, wipe BB5 from your mind and never consider them again. the outside pad adjustment on BB7 seems like a small improvement, but it makes a world of difference when adjusting. also the BB5 pads are towed in making braking very squishy and extremely difficult to adjust (I say this as a mechanic who has worked on many BB5s and rides BB7s).

Strengths:    Inexpensive, sufficient power. You never have to bleed them.

Weaknesses:    Not as powerful or as easy to modulate as hydraulic brakes.

Bottom Line:   
Bottom line: These are the best mechanical disc brakes you can buy. If you take the time to set them up properly and adjust them periodically they can outlast your frame. They wouldn't be my first choice for epic downhill runs, but for XC they have plenty of power. I guess they are heavier than high-end hydros, but I'm not a weight weenie so I don't consider it a weakness; especially when you consider how much cheaper they are. Oh, and if you're wondering if these are worth the extra money over BB5s, they absolutely are.

Strengths:    Powerful, easy to adjust/install, look good, extremely smooth.

Weaknesses:    The avid rotors squeal a little, but it does not affect braking power, a tad heavy (if you care)

Bottom Line:   
Buy them. If you don't want to spend $100 apiece on hydros and still get great performance, you need these. They are far superior to other cable brakes in my opinion. Paired with avids speed dial levers they have adjustments not found on hydraulics.

Bottom line: If you don't have them you should get them

Strengths:    Low price.
Easy set-up.
Great stopping power.
Reliable.


Weaknesses:    None

Bottom Line:   
I installed BB7s on my wife's XC bike.
My son installed BB7s on his XC bike.
My wife and I just bought fat bikes, both with BB7s.
After adjusting them on my fat bike, I was compelled to write a review.
I love these brakes.
They are so easy to set-up, and they work.
I am a Clydesdale Plus and my bike weights 37.4 pounds without gear.
Yet, these brakes have all the stopping power I will ever need, even with the smallish 160mm rotors.
No, they are not as light as hydraulics; that is not an issue for me.
At least I know the BB7s will alway work and never need bleeding.
I have overly-finicky Juicy Ultimates on my XC bike so I know both sides of things.
I highly recommend Avid BB7s!

Strengths:    The brakes are flawless! Powerful when you need them to be! Almost no maintenance needed apart from a 5 seconds to dial in a pad.

Weaknesses:    A little heavy (but i don think someone with a 2000$ carbon frame wouldn't afford something lighter in the first place), so normal weight for normal bikes. Short life supplied brake pads.

Bottom Line:   
I upgraded my brakes from Tektro IO's and man there is a difference! I ride 185 front and 160 back G3 discs which i think are more than enough for a hardtail. I made till now more than 600 km an all types of terrain (from dusty to extremely wet/muddy) and had no issues. Together with the SD7 levers i think they are above same price (50 euros) or even a little pricier hydros.

I love the simplicity of these brakes. I think it deserved 5 Chilis if it weren't for the short lasting brake pads fitted when new.

Bottom Line:

Strengths:    Great feel and power once set up properly!

Weaknesses:    Takes some time and experience to setup properly.

Bottom Line:   
Invest in a nice quality cable/housing and lever. Then follow detailed instructions that can be found on this forum for setting up the caliper/pads. Break them in HARD then enjoy for several years!

Strengths:    affordable, adjustable, effective

Weaknesses:    even with stiff cable housing, they can't touch the power of SLX 666s

Bottom Line:   
For years these are the only disc brakes I used. They still are on my 29er SS, and one other bike. I put SLXs on my more aggressive bike and am impressed with their power. I always use 1 finger braking with my BB7's, but have to put more finger into it than with the Shimanos. The modulation is great with BB7s, but that might be another way of saying I have to squeeze pretty hard to really stop.

Strengths:    Simple to set up and adjust.

Weaknesses:    cable actuation can get rough over time

Bottom Line:   
I have been riding with these brakes for many years and through several updates to the design.
They are pretty much bullet proof, particularly if you set them up with the Gore RideOn cable set.
Contaminated cables were the potential weak spot of this system, but with sealed ride on cables you simply can't go wrong.

Strengths:    Stop well, easy to adjust, price

Weaknesses:    Haven't found any

Bottom Line:   
Great mechanical disc brake for the price. Upgraded from bb5 (which suck). These have way better stopping power and feel great with the speed dial 7 levers. The pad size is about twice the area of the bb5's and they don't stick to the rotors. Easy to install and maintain. Theres probably plenty of other mechanical discs that preform just as well but none for this price tag.

Strengths:    They slow your bike down

Weaknesses:    None

Bottom Line:   
Nice modulation, when paired with speed dial 7 levers (or better levers made for use with mechanical systems) you'll have adjustable modulation. Single finger braking and just overall awesomeness. Enormous upgrade from the BB5's on my bike that came stock with it and not feeling jealous over the hydraulic brakes I've used on demo and rental bikes. These brakes provide all the braking power I'll ever need.
