what brake pads do you run?

Square Wheels

The ones they came with. They work great.

Onyx Carbon Brake Pads - Boyd Cycling

bt

cool.

do you ever get squeaking noises from them?

Square Wheels

Nope, they stop great and are very quiet. I've been very happy with me wheels (and brakes pads).

bt

I was using the "old style" and even bought new sets and could never stop the squeal.

Glad to hear the "new style" is better.

anyone wanna buy a few sets of old new pads? lol

StanSeven

Do you have them slightly "toed in" with the front edge making initial contact? Just about any pad can squel especially when the surface is smooth and slick.

bt

yep, I've tried it all.

curious as to why they changed to a new pad.

MikeyBoyAz

I have both the new and old. They both still squeal, I tried toeing them in, but they didn't shut up. I don't actually mind the noise.

I have also tried cleaning the brake track and contact surface of the pads, but no improvement.

bt

I've tried the cork bontrager pads and they work swimmingly, fwiw.

I have a pair of the 58mm carbon clinchers and I have only used the pads that came with them. Since they are race day only wheels for me I keep the brake track and pads really clean and I have not noticed any squeaking ever. I have also been nothing but extremely pleased with these wheels. They are fantastic and worth every dollar.

bt

I keep mine extremely clean too, lol.

who said they aren't fantastic?

MikeyBoyAz

Not me either, mine are the 60s and they are bomb diggity.

I didn't mean to imply that you were not satisfied with your Boyd's other than the braking sound you are experiencing. I was just giving them a shout out is all.

The newest brake pads we have (the Onyx ones) are designed to work with our newest rims (with the Unidirectional carbon fiber and the gray valve tag on the rim). With that I have been unable to get any squeal at all no matter how hard I try with many different brake pads and many different rims as examples.

Some of the older model stuff (the narrower V-shape, or our newer stuff with the 3k weave) is possible to squeal a little bit. It's not so much a function of the brake pads, but more about the rim finish and weave. I had tried a few brake pads with some of the older model wheels and could never completely eliminate the squeal, although it was pretty random.

Toeing in the brake pads is definitely the best solution. Keeping the rim and the brake pads clean with a rag and rubbing alcohol is also a great way to keep the rim silent.

If you don't mind answering, which rims do you have?

So can I use them with non-Boyd carbon rims? Or will that trigger the asplosion?

I know it's inevitable, I just want to delay it for a few more miles.

bt

Not sure, I have had them for about 12-18 months.

coachboyd

We have not done testing with any other rims to know exactly how they respond or work in regards to temperature.
But, the pads are made from a very well know brake pad manufacturer who makes a lot of pads for all different types of carbon rims. The whole point was to help keep the temperatures low while also providing good stopping power. They should work just as well as any other carbon specific pads even if you are not on our wheels.

coachboyd

Those are our 2013 model 44mm clinchers. Did you just get the Onyx pads? I have noticed it is possible to make the pads squeal a bit on the rims with the 3k weave.
Definitely toe in the brake pads a bit so the front hits the rim first. Also, clean the brake track and the pads off really well with a rag and rubbing alcohol.

bt

I do not have the "onyx" pads. Mine started squeaking when new so I bought more "old style" pads. they squeaked too.

I only learned of the "onyx" from this thread.


I've been running bontrager cork with good success.


sorry for the confusion.

popeye

I'm using Black Prince on older Boyds no squeal. 58/50 3 years old now, ~15k miles zero problems.
