I am thinking of getting a new frame built, or maybe buying a used one. Would like it to be as modern as possible, but still as backward compatible as possible, if that makes sense.... So, rim brakes, threaded BB, DT gear lever bosses (not just cable stops), round seatpost, not too worried about the headset but it must be some sort of common standard, not proprietary...

I thought getting shot of cotter pins was nifty. Im so retro....

Your over thinking and worrying....just buy a new frame and have all the bosses welded back on.

That's what i did.

Its a good thing we have so so many common standards, it makes life much easier these days.

re disc brakes

he hates them - although he is a bit weird about physics. All brakes operate by causing friction between the contact patch and the road; 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. Although you DO need spokes which can handle more force since the rim caliper handles forces through the rim and then supports the rider through the crown race. Whereas the disc caliper exerts force to the hub and up the spokes to the rim and then to the contact patch.

And I have never had brake fade with discs....after massive alpine descents....that's with Hope X2s using DOT.

I think there is lot of ill-founded assertion in his analysis.

meanwhile back in the real world.....

and that's a much better-grounded analysis with an empirical base.

They're pig ugly though and should have been left on motorbikes..

If it’s old tech compatibility you’re after, hand built money can get you a very nice old frame.

so talking of new road frames, my Sabbath Silk route frame arrived today from Spa Cycles. Titanium with some funky shaped tubing going on, plenty of braze ons, straight 1 1/8 headtube with standard bsa threaded bottom bracket. The welding is exceptionally neat though the rear canti hanger is a bit agricultural.

It's as modern as I plan to go.

It's technically a light tourer but has similar geo to my lynskey peloton road bike. I think between the silk route and the Yates expedition I will have all my cycling covered.

Feels a bit scary thinking about selling everything else. What kind of man cave only has two bikes?
