I have a set of trp spyres slc that I've just fitted, and whilst the braking performance is fine, they rattle like a bag of spanners on anything remotely rough.
I'm pretty sure this can be traced back to the brake pads which move around quite a bit in the caliper, to the point that when I hold the brake and rock the bars forward it feels like the headset is loose, there is so much movement between wheel and fork due to pad movement.
Anything I can do about it?
How are you with introductions? Spyres, meet bin. Bin, meet spyres - a match made in heaven 🙂
Running Spyres for 2 years rattle-free - suspect the pads haven't been installed correctly
Are you missing the leaf spring between the pads? Are they original pads or third party replacements?
I'd check and see if the anti-rattle / pad springs are properly located and all fasteners are properly snugged up. I mostly use hacked XT brake pads, but even with stock pads I've not had an issue with rattling.
Set up properly with decent compressionless housing they're pretty good ime.
I had this with mine. Found they just don't like anything else other than OEM pads.
Everything is brand new, the pads are original, and there is a spring in place. When you remove the wheel you can move the pads up and down quite a bit in the caliper which produces the same noise.

I was under the impression they were reason ly good as mechanical options go. They replaced some god awful pro renders I had, but whilst the spyres may stop you better at least they were quiet. No way Im going to be able to ignore the noise, it sounds like something is loose on the bike, and even if that's not the case it's hugely irritating
Well, something's amiss. I've got two bikes with Spyres on, one for four years and the other for two, and haven't had any rattling out of either of them. I don't recall being able to waggle the pads around in the caliper…
I assume both front and rear are having the same issue? If not, have you tried swapping the pads?
There should be a retaining bolt at the top of the caliper which goes through the tabs on the pads; I take it you're not missing that?
There is movement in both sets of pads, but only rattling from the front. All retaining bolts present and secure.
One thing I have noticed, the front which is a slc has a wee plastic cover over the caliper presumably to prevent dirt ingress whilst the normal spyre on the back doesn't have this. I've removed it to see if that's the issue and will take it for a quick spin now to see if there is an improvement
Problem solved, quick 5 min spin up the cobbled road outside my house confirmed the noise was coming from the plastic cover rather than the pads. The pads still move but not noticeable when riding and the noise has stopped.
On assumption the cover is of no real value I'll leave it off for now. Not overwhelmed by their power so far tbh but since I've only ridden it up and down the road hopefully the pads will bed in a bit. Better than the death traps they replaced, but probably less powerful than my road rim calipers Imo.. Which tbf I have always though provided plenty of stopping power
I had this with mine. Found they just don’t like anything else other than OEM pads.
I've run them with the original pads, Uberbike pads and now Shimano all without any issues. Strangely enough though I had a creak I was convinced from the BB which disappeared when I changed pads.

Have you checked the cable attachment is correct. I think it was Peter Poddy who posted a couple of years ago about how it's very easy to get it wrong. Plenty of people will also tell you that they really need compressionless outers to work at their best.
Also the OEM pads take a bit of breaking (braking?) in. First time I tried to stop with mine, there was, a small amount of sphincter puckering... They soon bed in and are pretty hassle free.
Have Spyres on two bikes for years/many many miles - no rattling.
Cabling is fine, they work fine, just not particularly powerful. Perhaps my expectations were a bit too much, but they are perfectly adequate for the riding I will be doing on them, with the added bonus they aren't as ugly as most mechanical calipers

That's my experience too.

Cable operated brakes can only be as good as the cable setup. The mechanism of the Spyres is good, so I suspect the problem lies with your cables, or your levers are flexing.
The braking performance is good now but will get progressively shitter, before getting dangerous, as winter sets in. It'll distract you from the rattle at least.
I've used a lot of mech discs and I like that most of them are simple and shit from the start but maintain that year on year. Spyres are gits because you think they're alright but then they get much worse than the worst shitty mechanical disc.
My experience with Spyres is that they need compressionless outers to work decently. The original pads aren't great, particularly in the wet. And you need to initially adjust the lever bite with the cable adjustment then keep the play in the system limited using the individual piston adjusters.
I also stuck a 180mm rotor up front, which suggests I wanted more stopping power, but then I run a 203/180 combo on my mountain bikes.
I don't think they're perfect by any means, but if you set them up right and use good cables, they do a decent job. I guess it also depends a little on your expectations.
