Am preparing to chow down on a major slice of humble pie as I prepare to move over to discs.
In my defence it's only because my gravel bike has turned in to a fairly hardcore CX bike recently, lots of very muddy, rooty, rocky trails, and I've just destroyed a set of very expensive Pacenti rims in a very short space of time 🙁
I know Shimano sintered pads work well for me, that's what I used on my MTB year round, but they're really difficult to find in a TRP Spyre pattern, I *think* I've found some which appear to be for e-bike use!
Is the sintered compound the same across all manufacturers? I seem to remember poor results with SRAM sintered pads...
In short, no...
But poking a bit deeper... Why would you want to use sintered pads on bike that, in theory, won't see enough breaking to make them work as they should be with high heat and prolonged usage.
... unless your HC CX verges on the edge of enduro/downhill riding...
From my personal experience with Spyres I had the best results with Swiss Stop green pads.
Cheers!

That's good to know Ivan, thanks.
I understand exactly what you say about sintered pads.
My bugbear with discs, and the reason why I have persisted with rim brakes for as long as I have, is squealing in wet conditions (see previous threads, ad nauseam). Of course, for the sort of filthy muddy conditions this bike typically sees, there will probably be enough grit and muck in there to prevent squeal anyway.
In my previous life as an MTBer I remember thinking that the best compromise between performance and noise was actually using Shimano sintered pads, which I know goes against the grain of conventional thinking.
YoHandsome off this forum did some experimenting recently and seemed to confirm that Shimano sintered were still a bit quieter in wet conditions that the equivalent organic pad. I just figured it was worth a shot.
Also I'll be running the smallest rotors I can get away with to assist with heat build up, this bike will never see any prolonged or hard braking!
edit: also when I say 'hardcore' I don't mean fast or gnarly, just muddy!
Gotcha...
My personal experience is that all sintered pads are noisy unless they got some proper temperature.
Especially noisy in filthy conditions.
Even properly beaded in.
On the other hand, green Swiss Stop were probably the quietest pads I tested so far. Still have Trickstuff organic pads to test. They will go into my Forces once I'm done with current pads.
... that are green Swiss Stop 😀
Cheers!

LOL. So your main objection is disc brakes squeal in conditions when rim brakes are quieter, but significantly less effective? I agree though, no-one likes a squealy brake.
Anyway, I buy cheap resin pads (£2 a pair) from Ebay. They work fine, and last fine, and at £2, I don't begrudge replacing them if they are "nearly done".

I found the rim brakes plenty effective, good pads, set up properly (straddle cables as low as mud clearance would allow). Literally zero instance of being underbraked.
Is a moot point though, I have conceded defeat when it comes to the CX bike, my horrifically concaved Pacentis make me cry a little inside...
TRP spyre use the B01S shimano pad, used to be £3.50-4.50 each delivered pre covid.
ps. the trp spyre are pretty good till you upgrade to proper hydraulic brakes, latest 105 are very powerfull
TRP spyre use the B01S shimano pad
Yeah, I was looking for a sintered equivalent. The official Shimano replacement appears to be the EOS1, but the crux of my question was whether other manufacturer's sintered compound was likely to be identical to Shimano's. the EOS1's are £20 a set...
I agree though, no-one likes a squealy brake.
I do. I love seeing OAPs leaping for their lives when they think they're about to be run down by an HGV.
I think resin are the quiet ones. Got 2 years out of a set on road bike before swapping to race matrix. I now have a 100db scream horn at my finger tips, which in fairness can be useful.
Wellllll.... Apropos nothing, I've got a Shimano sintered on one end and a resin on the other ATM and just had reason to swap them round.
The braking with the sintered on the back wasn't great but is betterer on the front where it howls like a banshee when wet. The resin is better than the sintered was on the back and I can lock the brake at speed now (cooool). 685/785 hydro for the record.
Not sure what that tells us but there you go...
Thanks Boblo, reading reviews of my preferred rotors (Swissstop Catalyst) suggests they're quietest with green Swissstop pads, so it seems most sensible to run that combo for now.
The 685/785's are on Avid discs. I run Avid G2's or G3's in the main as they give better braking than the TRP stuff you get with Spyres and are massively cheaper than Shimano's fancy pants ones.
I run Spyres on most of my gravel/Audax/touring bikes so have a collection of TRP disks. All changed for Avid. Never tried Shimano disks. They might just be a(nother) revelation. I do have one bike on Swiss Stop discs and Spyres and can't really tell the difference between that combo and Avid's/Spyres. Both with sintered pads. The TRP OE pads are frighteningly ineffective until broken in then not quite as good as sintered.
I buy the sintered pads from Uber who I've got some Kevlar 'racing' pads from as a treat... (actually I cocked up the order...). We'll see how they go (stop) once I've got through my current jobbies.

Haha, stumbled across this thread. My sintered Shimano L04C with 105 R7000 calipers and Shimano rotors (currently MT900) are quiet in the dry and quieter in the wet as they seem to burn off road grime rather than absorb it and get thoroughly contaminated like resin pads often do - you get an initial squeal that dies down quickly.
My main gripe with resin is performance in the wet and susceptibility to contamination, if I only rode in dry conditions I'd probably use L03C resin pads. My concern with sintered pads is rotor wear, hear some chew through a set of MT900s in 6 months. On the flip side, resin pads wear out faster so maybe it's a net 0 sum game.
