Just curious as to what you used as a radius, so I can compare to my wheels and tires?

Hey, btw, I started restoring it... making a singlespeed for the road out of it. Put a brand new Campagnolo Veloce on as a front brake (had to drill the semi-sloping Columbus fork crown for that). I can't believe how WEAK the spring is in those brakes! Doesn't Campagnolo have experience and make quality? With new cables and teflon liners, no bolts too tight either, they go back out really slowwwww when you release the lever.
Found some nice Continental tires in my storage area... a 23C for the rear and a 19C (160psi!) for the front. I really had to put all my weight on the floor pump in the end as it was approaching 160. What is nice about old tires you had in storage, is the rubber has had a chance to dry out and grips better in the turns. That's a fact, even with the new compounds.

I'm wondering if the 4mm extra tire dia in the back will change the angle much... I'll check with my inclinometer, because you can't predict mathematically... different tires, different diameters, different pressures... you can't predict exactly how they crush will play out under my 210 lbs. I suspect that this will just have to be measured in the field... once that wheel is built.

I have clinchers I'm putting on (still need to build the rear wheel though - broke my bench vise trying to get the freewheel off a wheel so I can recover the nice Wolber Alpine rim that's on it to build the wheel with it). I've had that Wolber Alpine rim for over 2 decades now, and it just won't die! It's really been through a lot!

But I'll pump up the original track wheels and tubulars just to measure what the original radius was that this bike was designed in mind with. It always varies a bit, from wheel to wheel, tire to tire... so it's nice to have the original wheels. OK I know... I'm off on a tangent (pardon the pun). Couldn't help it - I'm enthused about building it up again and getting rid of my back-basher (if you can believe something is harder on the back than this bike - well indeed there is: a 1984 Canadian Olympic Team aluminum Canondale road bike (an actual spare from the team - has no-labels on it as sponsorship wasn't allowed in the games back then).

So, until I find my Cambio Rino I'll just ride this... and my recumbent... and my mountainbike (hey, winter is coming, so although the child seat is coming off, the winter spike tires are going on soon).
