I still reach for the down tube sometimes. I got my new fancy 21st century bike last year with SRAM indexed shifters. Has it drastically improved my riding experience when compared with friction shifters on the down tube? Not a bit. The new shifters are nice, and the new bike rides beautifully, but to be honest I see clicky brifters as a bit of flim-flam.i have a few old bikes from way back a nice Raleigh Router, an old Elswick , a Raleigh Rapide, also a Philips
and a BSA Tour Of Britain, all of course had the down tube shifters i enjoy riding these
bikes just as much as my Trek.
But to go back to my post - the mech I was thinking of was an early Campag mech which had no jockey wheels/chain tensioner. Instead the wheel slid backwards and forwards in the dropouts when you changed gear. The rider reached down and pulled a lever that disengaged the quick release on the rear hub before changing gear, then tightened the hub again after changing. Crazy, but (from the pics I've seen) beautiful.
