Yeah, I measured the wheelbase and it's about 1/2 an inch longer than what the spec sheet shows. Within normal boundaries considering a new fork, I imagine?

New fork, the vagaries of measurement and a handmade frame. Better too long than too short.

With short reach brakes, I'd expect the original fork's ATC measurement to be closer to 365 and according to 'Fork Lengths' on Sheldon's site, it could be even shorter (Tange 7B @ 363.5). This would steepen up the HTA and reduce flop and is probably the best replacement dimensions. As has been said, rake of anything between 43-50 should be magic.

Agreed, as I mentioned in my first posting. Andy

Sure, but when I said it people stopped responding so... :lol:

Seriously, I should read more closely. I saw someone based their calcs on a different number so didn't realize we'd stated the correct answer.

I have a 912 fork from that model year and it measures 385mm.

what size tires was the 912 built for? I took the OP's catalog page to mean he has a 1200
