Just the job
Easy to fit (about 10 minutes) and easy to adjust. Quality product at a very good price.

Value disc brake, replacement for a failed one
They work, but require fairly frequent simple adjustment. They are not very robust for daily usage and hence regular adjustment, as the inner adjuster nut and plastic cap seem to burr easily and become unusable.
This was a replacement for one that came with my bike, and has only been in (weekday daily) use for a couple of years.

Poor performer and endless faff
I've been disappointed with these from the word go. I've wide experience with both calliper brakes and hydraulic discs and frankly these underperform compared to both.
The design seems fundamentally flawed: they are the only brakes I've ever used which don't have two-sided activation. These have one fixed pad so when you apply the lever the movable pad has to deform the rotor to engage with the fixed one. It's no wonder I spend so much time fiddling to try and stop them rubbing and get decent braking performance into the bargain.

Functional but looking dated
When compared to the new crop of disc brake calipers - these look decidedly dated. They look chunky and haven't changed much (if any) in design in the last 15 years. The road calipers use slightly different pull ratio to the mountain bike ones - but other than that - they are the same brake. I've always had good performance from BB5s, very similar to BB7s in braking power. The difference being the inboard pad is fixed on the BB5 brake and a little less weather proofing.
There is a knack to setting these up - inboard first - followed by outboard pad. A bit of trial and error to. But once bedded in - these have been very reliable and fuss free.

go for avid bb7
Have got two cyclocross bikes one with avid bb5 and one with bb7.
The bb5 is disappointing. Constantly needs adjusting and just feels disappointing, and scary on steep descents. As it is my commuter and as my commute is flat, they do their job just about. Avid bb7 feel much better and perform brilliantly.

I have these fitted to my boardman cyclocross. Unfortunately, the item requires constant tuning and does not provide very powerful braking. Overall very disappointed!
