I pulled my ‘82 Mercian Colorado off the pegs it has called home for several years. A recent interest in 80s Shimano indexing developed from the last two Clunker Challenge bikes led me to reading, which led me to realize the shifting issue on this bike was the Dura-Ace rear derailleur, which won’t play nice with less expensive Shimano parts. I wound up taking the Sachs New Success off the ‘71 Mercian KOM I am building for my son. Sure enough, a little fiddling with the barrel adjuster and it works beautifully with the indexing 600 dot shifters.





Before I fitted the Sachs mech I dug put a 300EX Exage and tried it. It worked nicely, but I think it’s a better match for the MicroNew brifters on Eli’s green machine. All that’s left to do for now is to polish up the Sugino 165 cranks and wait for the new BB to arrive.
