Back in the days, was only 15 ( about 20yrs ago now )
Peugeot road frame 531 pro cromed forks / rear stays
Black mettalic with the peugeot stripes
Cinelli Record Bar/Stem and Cork tape
Shimano Ultergra 600 gruppo and Campag Omega Strata Hardox V section clinchers with Michelin hi light roads
Selle San Marco Rolls saddle
was worth a bit then, wish i'd kept it
Next best would be my old Kona Cinder Cone, still going strong with the original bottom bracket, headset, chainset, stem etc, upgraded from Suntour XC to Deore XT / Thumbies
was funny how those has an extra click so you could run a road cassette with an extra cog 😉
Last but not least my old raleigh grifter – bombproof
