Anyone know anything about disc brakes?

Yes they might be, they insisted that Shimano told them 140 would be enough and I assume that for "normal" people it could be... but not if the rider+bike+extras are about 100kg or more :(, and the road descents are as steep as they can get (like @hippy with full equipment for the TransAm)

If, with all your kit, you kill the brake at 140mm you'll also kill it at 160mm too.

If you are really bothered about overcooking it use cable pull calipers. The fittings might melt, but they'll keep working...

The front adapter for flat mount works for both 140mm and 160mm by turning it around. But you have to remove it because the bolts for the caliper go in reverse. So no, you dont spare the fork bolt threads...

140mm side up

160mm side

Ah yeah, nice one. Good spot.

Shame they couldn't do flat mount front like flat mount rear, but I guess aeros and structural considerations of the lower fork leg prevented that.

As it stands: that's a fucking mess.

I think the reusable adapter is a nice touch, but yes the threads in the fork design is not an improvement.

Make new standards = people buy new stuff = Proffffiiiittttzzz ;)

Any recommendations for not too pricey centerlock disc rotors?

Mid-range Shimano ones (RT-5x, RT-6x etc) in Planet-X, CRC etc sales. They generally get loads in for OEM, but struggle to shift them individually.

As it stands: that's a fucking mess.

Why? Isn't that a decent solution being able to flip the adapter for common disc sizes?

Disc help needed...

when I use my rear brake it makes a creaking or crunching feeling. Braking power is still there, and nicely controllable and it's not a loud squeal, its a feel of weird friction or something..

any ideas?

dirt behind the pad (between piston and pad)? or dirty pads/rotors?

Worn pads? Uneven wear on pads? One of the 'legs' of the spring is rubbing the rotor?

If you use a flat mount fork with post-mount calipers you get what you want :) (extra bolts...in a cheap replaceable part .. and small disc sizes)

right one

Nothing there is flat mount.

sorry, where? I don't quite follow...

No where. There is no example of flat mount in your images.

Never mind.

The forks are no?

yes, and the adapters (flat mount to postmount....)...

Is it? I thought flat mount involved the screws threading into the caliper? Isn't that the point of it?
What's the benefit of that over post mount on a fork?

Also, sorry for saying you were incorrect. I was.

No problem :) I just didnt understand your comment.

What's the benefit of that over post mount on a fork?

Howard was talking about having separate bolts for the fork and caliper because people screw up the bolt threads over time. This way you can adjust the caliper position and fiddle around, and if/when the threads break you can replace a cheap part and not the whole fork.

(or read earlier in this discussion thread ^)

Maybe someone that knows how UpgradeBikes works and the UK retailers way of doing things can explain me this:

TRP Spyre C (Flat Mount version) appears in stock in UpgradeBikes Store (ships only to UK).

But I can't find any online shop that offers them, neither asking if they could get them for me (Wiggle, MerlinCycles, ProBikeKit...). Neither amazon, ebay, etc...

PS: Also this just came in the mail, I hope to test them soon!

That makes sense if your using a post mount caliper on a flat mount fork. You can adjust the caliper relative to the adapter rather than the fork.
But if you use a flat mount caliper on a flat mount fork you still have to loosen the adapter bolts to the fork. So I guess it simply looks nicer and that's it. Weird.

@coventry_eagle @dancing james in case you cared - turned out I just need to tighten everything just a little more bit more, all good :) thanks for tips

TlGHTEN ALL THE TH1NGS!

Spyre C are OEM only, which is why none of the other shops stock them
