Having completed my 100 km (115.8 km, actually), I managed to complete the final stage of the Clunker Challenge - sending the bike on. I swapped out the Vetta saddle for the Avenir that came on the freebie Trek 820, then retrieved last year's Centurion LeMans and swapped out its 23 mm Continentals for the 25 mm IRCs. I removed the Look pedals and fitted its stock MKS platforms. I lowered the seatpost back down to a sane height. I cursed because as always the rear Continental was a tight enough fit that I punctured the tube. Finally, I took pix and posted it on FB Marketplace for $75 Sunday afternoon. Got a message about it today offering $60, grabbed it on a trip home to walk the dog, and there we go!
Final photos of Champagne Charlie - hopefully he has a good home now!
