these are the cheapest new production high quality thumbies you can buy (dia compe, paul, vo, all do more expensive ones), which you'd have to run in friction mode being 7 spd

heres a slightly left field idea. These are reasonable quality stem shifters. Indexed 7 spd. Put them on your bars. Maybe with a shim. Being stem not DT shifters they have a cable stop. Maybe even remove one lever and find a seperate clamp for it.
