Serotta CSI : Another tire clearance data point

[Flinch]

Pirelli P Zero Road TLR set up tubeless on my 1996 57cm CSI, stock metal fork, Ultegra 6800 brakes, DT Swiss R460 rims with 18mm inner width.

Front 32mm tire measures 32mm at 65PSI, with 'just enough' clearance either side and plenty from the brake arch. The limiting factor is the fork blade clearances, with plenty at the arch. I couldn't go any wider on the front without a cringe factor. Boy, that fat 32 looks good out front!

Rear is a 30mm, measures ~28.5mm at 65 PSI, and again, enough clearance. The rear clearance imiting factor are the chain stays on either side, not the apex. I could go a full 30mm true width on the rear.
