Been having a bit of a drama with the correct choice of tyres too. The old faithfull for me is the Panaracer Timbuk II, but by the 92/93 model year Ritchey was suppling the excellent Z-max.
Thanks to Jeff, (first flight bikes)....the retro world can rest easy, as im sure most of the retro community know, he has thankfully been the contributing factor of the re-introduction of both types of tyres.
The Z-Max evolution looks like a great tyre, (although i have yet to use the new evo)...its light and foldable kevlar.
To my mind the Z-MAX could be the more obvious choice...... :?
