30 lbs seems high. I would have guessed around 25-27.My 86 paramount is 22 and its a larger frame at 61cm.
Yeah, looked at my old post about mine. I had it right at 22 lbs even with saddle, bottle cages, and Look Keo pedals. Mine was running DA-7400 to include the clincher wheels. Tange Prestige is light stuff.
