Modern standards - I need updating!

; so the force acting on the crown race on the fork is the same irrespective of whether the brake is mounted at the top of the fork or near the hub.

Is it? Gut feeling would be that this is incorrect. Need to calc it out.

Road... That's why it's in the road section

That’s what I thought - the advice about boost threw me - and then I’ve just found that boost is indeed a road frame thing …

Relatively small brake rotors on road bikes can get overheated.

Thruaxles
The marvelous thing about standards is that there so many of them.

There are modern standards that I need some help with, hoping someone can maybe clear things up!

Forks - What's the standard steerer size nowadays? Is 1 1/8" still widely used and available? What about tapered steerers?

Mech hangers - i don't really like SRAM, but must admit that the UDH standard looks pretty good. But will an older (7/8/9 speed) rear mech fit and work with UDH?

Seattube diameter - thinking front mech clamps, I think we had 28.6, 31.8, 34.something? Are they still the same, or is there a newer one?

BB - T47 looks like a good idea, I have avoided anything other than BSA/ITA threaded until now, but T47 seems to be an improvement, possibly?

Anything else I should know about? This would be for a rim brake frame, so don't mention discs...

Are you looking to get something custom made or asking in regards to building up a specific frame? Both carbon framesets I've had (2014/2015) used tapered steerers. UDH is afaik thru axle/boost spacing. Front mech clamps still use common sizes, newest top spec di2 stuff offers clamp mount (31.8/34.9) or braze/direct mount. T47 is basically an oversized external BSA, larger shell diameter allowing larger diameter cranks for stiffness etc, different thread than BSA. As others have said avoid pressfit and derivatives.

Haven't even heard of much of what is being discussed on here. That shows where I am with things
