Developed for e-bike use and when stronger braking is required, like road discs * Quiet compound for low vibrations * Features increased heat resistance for heavier bikes and higher speeds
TRP Spyre brakes... AVOID MUD
Moderator: Moderator Team
We are currently using the Swiss Stop Disc 15 Sintered pads with Ice Tech 6-bolt rotors and get good, quiet breaking although a bit of a short squeal under wet breaking. Just looked at the Swiss Stop site and notices that they are now offering a 15 Disc e pad which they rate as a 9 out of 10 for heat tolerance, longevity, and modulation.

Seems like modding the backing plate of the XTR 985 pads gives you the best brake pads for the money for these brakes. Interesting enough, the XTR 985 pads say they work with the Shimano 515 brakes, which is the pad the Spyre used. I guess the Spyre caliper body has a little less tolerance??
There seems to be a widespread feeling among Cyclocrossers that disc brakes can't handle mud.
Now I come from an MTB background, where races are often very muddy. I've never had problems with brake pads being used up in a 1-hour race, so when it came time to build a CX bike for this season, I chose hydraulic disc brakes (Ultegra Di2 hydraulics). I put about 800 kilometers of training on the original (resin) pads, and 5-6 races, 3-4 of which were very muddy, before I changed them. And I changed them as routine maintenance, not because they were finished.
So in my experience, hydraulic disc brakes are excellent for CX. Mechanical disc brakes may be different. And I haven't used rim brakes in mud since the late nineties, and I'm not going back.

If you guys try sintered metallic pads and you are still grinding through them at an unacceptable rate then there are several options for solid rotors.
Sram makes the sold sweep which is the least WW friendly, and may only be available in 140mm it seems,(http://www.chainreactioncycles.com/us/e ... -prod74216).
Magura makes a "wave" rotor which has no cutouts. I am unsure how the wave pattern would fit into the pad wear picture, but it seems like it would probably be somewhat better than a rotor with cutouts, as the cutouts are claimed to be the source of the problem as they trap grit and continually reintroduce it to the pad surface. It seems tougher to predict how they would compare to a non wave solid rotor though. Additionally, Magura rotors are thicker than most of their competitors, so you would want to verify that they will clear your caliper slots in the Spyre etc...
Galfer originated and continues to make a wave rotor. I have never measured their thickness, but I think they have broad compatibility so they may be thinner than the Maguras.

I come from a MTB background as well and have never had a problem with needing to replace XTR 985 resin pads in the middle of a season.
I'm building a new CX and gravel race bike and wanted disc brakes. I was originally going to go with the Ultegra hydraulics but it looked like weight penalty was too much. I ended up getting Ultegra Di2 with TRP Spyre's.
To be honest, the only reason I went with disc brakes is to be able to run MTB wheels while gravel racing. I couldn't find a wide enough rim that would also build up a light wheelset without going to disc.
I'm taking a weight hit of a little over 1lb with a custom steel frame, and I didn't want to add another 1+lb to that with hydraulic discs.

Good to know I'll get some m515 pads for next season..
Installed the Swiss Stop 15 Disc e pads on our first generation TRP Spyres with Shimano 6-bolt Ice Tech rotors and am impressed with the braking and how quiet these pads are compared to the previous Swiss Stops.

Re solid rotor options, the Avid Solid Sweep looks to be discontinued with only limited quantities of 140mm stock left (I need 160mm).
Carver Mud Runners appear to be the only solid steel option currently being produced. Good looking unit with an alloy carrier.
I've opted for some Hayes Mud Cutters based on price. They have a sparse drilling pattern but are significantly more solid than the stock Hayes CX5 rotors on my bike. Running these with full metallic pads will hopefully provide extended pad life.
The Carver website advises a longer pad bedding in time due to reduced abrasion of vents and also warns against riding situations with extended hard braking generating sustained heat. I guess the latter is why solid rotors are such niche items?
