Cons: -Cheaply made
-Only one side of the rotor modulates and is adjustable
-Constantly require adjustments
Recommendation: The previous reviews of these brakes blew my mind. If these come stock on your bike, throw them away and upgrade to either BB7s or Hydraulics immediately. These came stock on my hardtail 29er and I had nothing but issues with them. They only adjust and modulate on one side of the rotor while the other side sits and waits for the rotor to be bent into it to stop the bike. HORRIBLE brakes.
Pros: Good overall stopping power for mechanical disk brakes.
much better option than cantilever brakes
Cons: Brakes squeal when locking out.
Not enough braking power in extreme conditions.
Recommendation: These are great mechanical disk brakes for the money. For most applications these brakes work really well however, they are lacking, as far as stopping power, on extreme downhill situations. They are not as sensitive as hydraulic brakes so transitioning from one to the other will take some getting used to. The Avid BB5's came with my bike and if I had a choice I would personally have gone with a hydraulic brake set up but the BB5's are a great set for the amount of money you would spend to purchase them.
If you don't have the money for a set of hydraulic brakes I would definitely recommend these to anyone.
Recommendation: Once these are set up correctly they are bulletproof for the minimal investment on mech. disc brakes. MSRP is much lower than stated as well. A set (front and back) is even much less than stated.
Recommendation: These are the only disc brakes that I have experiences. I know there are better products out, however these have worked great for me so far. I had them installed by my local bike shop tech and I have had no problems thus far.
Pros: Very similar stopping power to the BB7s, despite what some people may lead you to believe. Same rotors as the BB7s. Nice and cheap! Step up to a larger rotor and you'll really feel the difference.
Cons: Missing the adjustment of the BB7s and smaller shaped pads. The roundagon rotors are pretty bulky but you can always switch them out.
Recommendation: An acceptable mechanical brake set that performs well given its price. Not the top of the line, but not priced or marketed that way either. A great way to get started in disc brakes with decent performing mechanicals.
Pros: They have OK modulation and are cheap. You can use your old V-Brake linear pull levers. You will eventually stop.
Cons: "CHEAP" with a small brake pad footprint and contact area. Pads glaze very easily.
Recommendation: These blow!! Anything other than an upright cruise on a paved trail will overload these and they will squeal like a stuck pig. AVID has great products and this is the lowest of the low mechanicals they make. Go with a BB7..you get big boy power with the same pads as the Juicy series.
