The Onyx Brake pad by Boyd Cycling is our newest and most advanced brake pad yet. It is good to use for any of our carbon wheels, clincher or tubular, and any model year.
The most important feature of this new brake pad is heat dissipation. We made a focus on a brake pad that will not develop high heat in prolonged braking circumstances. In our torture test that consists of continuous braking at 17KgF for minutes on end the highest temperature reached was 104 degrees Celsius. With the same testing lab, we tested the brakes at 17KgF braking power for 4 seconds on, 4 seconds off for an hour. The temperature would rise and fall, but the highest temperature reached was only 68 degrees Celsius.
These new brake pads also have great modulation and also brake feel. We tested these on the road for months before final production letting multiple riders try the brake pads and give their impressions. Braking is predictable, there is no pulsation, and the absolute stopping power is there when you need it. The final test before product release came in a criterium where Boyd was in a two person break. The breakaway companion took the final corner of the race a little too fast and slid out right in front of Boyd. He was able to slam on the brakes and go from 28mph to a complete stop in about 10 meters (albeit balancing on the front wheel doing an endo). This was the final proof that the brake pads have that ability to really stop when needed. Now you can have carbon wheels without sacrificing the braking power of an alloy wheel.
Longevity is very good on these pads. Like all wheels and wheel accessories, Altamont road going up and down Paris Mountain in Greenville, SC is used for testing. We have found that with going up and down Paris Mountain multiple times almost every day the front pads will last a few months whereas the rear pads will likely last at least half a year or more. Not too bad for a set of four brake pads that only cost $20.
One set come with four brake pads, enough to outfit your entire bike with new pads. Both Shimano and Campy style are available. Please note that on the first ride there may be a little material that comes off after the first couple times of using the brakes, this is just the top layer and is meant to come off. If you have just installed the brake pads for the first time you may not want to do a super hilly route on that first ride with the brake pads. The top layer of the brake pad can stick to the rim and that will accelerate the wear of the brake pads for that ride. It's encouraged that after your first ride you wipe down both the brake pads and the rim with a rag and rubbing alcohol. This quick step will only take a few seconds to perform but will greatly prolong the life of the brake pads.
Excessive toeing in of these brake pads will also accelerate the wear. A lot of time has been spent ensuring that these brake pads will not squeal on your carbon rims. You should not have to toe in your brake pads on these as much as a traditional carbon brake pad. This will also help with longevity.
