the much loved Panaracer Smoke Dart combo was only available with skinwalls
Here's a pic of my original Paramount. Back of the pic is watermarked FEB 93. Those are Smoke/Dart on it from the previous season, so the blackwall versions were available in 92.
Not the best pic of the Paramount, but the bike I replaced the Paramount with in 93, and those are definitely Smoke/Darts.
The bike came from the factory in 91 with blackwall Paramount KOMs (probably out of the Panaracer factory). Both my 91 Avalanche and Karakoram were spec'd from GT with blackwall Ritchey Megabites.
