SRAM Red compatible with Disc brakes ?
Is 10 speed (gen 1) SRAM Red compatible for use with a bicycle that has
cable-pull Disc brakes?
Will it require a different type of cable end per attaching to Disc caliper ?
Is brake pull ratio a concern?

100% compatible with mechanical discs. In fact i ran those levers on my son's cross bike with Avid BB7's for years for cross. My only recommendation is to use Yokozuna Reaction brake cables and housings. Mechanical disc brakes are highly susceptible to housing compression and power loss.

Can the BB7 model be adapted to flat mount? All I see is post mount and most frames these days are flat mount. I run SRAM AXS rim brake with Campy chorus brakes that work fine, but someday I may find a disc frame that I can't resist.

There are 2 parts to the system: The cable and the housing. There is no 'internal cable', it's just the cable.

IMO cable discs are a PITA, with the mechanical advantage requiring frequent adjustment to keep up with pad wear. Those HY/RD TRP calipers solve that issue though. Nice to see you can get em in flat mount now.

These are in my travel bike with s&s couplers. Hydraulics would be a mess in that application.

The HY/RD calipers are cable actuated with master and slave in the caliper, which provides auto adjustment.

Yeah, the Spyres are definitely a cut above other mechanical disc calipers, with the yoke to actuate both pads.

The TRP Spyres need adjustment around the same amount as my rim brakes did. Adjustment is the normal little knurled knob thing so it’s a minute or two to do. After using some BB7’s and some of the others with the single pad that moves, I’d agree that I’d want something other than that. There, you have to adjust the cable *and* the brake position too often.

Thanks for the info per clamping as I've not yet seen mechanical cable-pull Disc brakes to observer/understand how cable end attaches
to them.

TRP Spyres are pretty awesome, as well as BB7s which I have on my touring bike, but TRP Spyres are even better and come in flat mount. Super light, too.
Every once in a while (typically after rides including big, steep descents) I grab an allen key and adjust for pad wear, takes far less time than cleaning and relubing the chain, and the pads never drag because I can adjust the spacing.
Naturally they work fime with rim brake levers.

Do note - using the good cables with the slippery coating on them and compassionless housing to run it through makes it very hard for me to notice much of a difference from my hydraulic brake mountain bike.

On the R1 2piston at the moment. Compressionless brake housing and good pads get the best performance out of them. Been happy with them.
Don't really need the GT 4piston at my weight, but would like to see the braking difference on downhill runs.

I've been really happy with the Spyres but if the modulation were better, I’d consider a change since there’s no real weight penalty for me. Already have compressionless housing installed.

No Spyre experience. First disc setup went straight to JuinTech R1. I feel the modulation is very good.
