It's hard to beat John's offer, but I'll float this out there. I've got three pairs of the open-loop version the ones shown here on CLW site: https://www.classiclightweights.co.u...iction-levers/

Two pairs are silver, one pair is black, I think two of the three pairs lack the Simplex branding. Simplex resold to multiple companies, Mavic, Galli, others? They're intended for direct-mount but I have a compatible chrome Simplex 'S' band to go with them.

I see you saying you'd want to buy, but I'd prefer trading for mid-2000s era MTB/gravel Deore mech + lever, M5xx - M8xxx, 9-10spd and black preferred, 3x9 if front mech included. Of course I'm willing to toss cash in as needed.
