Quiet BB7 replacement pads

It's about time to replace my pads. If there's a better pad than the stock sintered metal Avid ones, I'm all ears.

My BB7s were remarkably quiet with the stock Avid "roundagon" rotors. With Shimano rotors (many more perforations in the rotor) they tend to be a lot more squealy.

Kool-stop makes pads - I use Kool-stop for my rim brake bikes...obviously the disc brake is a different animal.

Swiss-stop pads are an option too. They got a pretty good review from Competitive Cyclist. Caveat that with the knowledge that Competitive Cyclist is reviewing a product that they are selling! (Sheesh.) Competitive's Swiss Stop "review"

Thoughts appreciated.

I have juicy 7's on a full suspension Mountain bike, not sure if they would have a similar result. These brakes, esp the back one made incredible noise. I tried different rotors and cleaning the pads and rotor well etc. Also getting the caliper centered properly. It was frustrating.

My final solution was the cool stop red pads. I think the BB's and juicys use the same pads. mine only make the slight warble now and mostly when they are dusty. They are much quieter. If you need pad I would recommend them.

Those are organic pads, right?

From what I've found, the consensus seems to be that organic pads do produce much less noise, but wear much quicker, especially if used in the rain.

I'm watching this thread with much interest because my BB7s with roundagons squeal like Ned Beatty in light rain. It might be worth the extra cost of frequent organic pad replacement to stop that, but if there are other alternatives, I'd love to hear them.

I don't have any suggestions for really quiet pads, but being a cheapskate, I ordered my replacement pads off of eBay. I paid $6 a set for them instead of the $18 that Avid wanted, and they've worked and lasted as long as the original pads.

Checking eBay, I see that semi-metallics are going for $4 now, and organics for $8. I buy a few sets at once since most places will ship more than one for the same price or just a little more.

The organics are apparently quieter but wear faster. I've always gone for the long lasting, noisy option.

Only bike that's had noise issues is the Safari;it gets ridden year round in rain/snow/salt,and I don't always clean it properly. I've been running organics on it since that's what REI had in stock for the Shimano 495's. Pad life has been decent,I get like 8-9 months out of fronts and a year or so out of rears. This is all weather,hilly terrain,plus grocery hauling.

Pads aren't the only cause of noise. Dirty rotors obviously,but also make sure your calipers and rotors are tight. Any play will cause vibration that will cause noise. Also make sure your pads are in properly,any looseness will also cause noise. And make sure the caliper is centered and the pads are the same distance from the rotor.

Interesting about the organic /inorganic compounds. I looked at the cool stop site and there are red and silver pads for the Avid brakes. It doens't say anything about compounds. The rim brake pads have a detailed page on that. They do have a sintered one that should have some metal in it. The braking perfomance has always been great regardless of which pads. IMHO

FWIW, I tried Azonic pads (they were silver if that means anything) and they didn't help. Also, the backing plate was thicker and they were a pain to install.

One other thing that came to mind is with car disc brakes they often have the backing plate coated with a hard rubbery stuff or they come with goo to put on the back. I wonder if this matters for the tiny bike pads

I do know that mine are much quiter now even with the roundagon rotor in the back ( I bent the newer avid none roundagon and put the roundagon back). This is on a mountain bike that gets the rotors dirty pretty quickly.
