All said and done.... The Bianchi Project 3 (one of the first 700c/29er MTBs, early 90s), now a 700c gravel bike, before can be seen a few posts back. Went into the parts bin, Deore triple crankset, XT front and XTR rear mech. As an experiment I went with "MicroNew" brifters, they are copies of MicroShift R series (which I like the function), $68! Aliexpress to my door, lets see how they hold up (really hard to get parts these days so I might as well experiment)--so far they work perfect.
Painted the fork and polished up the frame, went with the original purple theme.
Converted the rear from seven speed to nine speed by swapping the freehub body and redishing the wheel. Stayed 130mm hub spacing as I swap wheels.... 9 speed because a have other 9 speed bikes so I have spares (like the XTR rear mech here) and a bit of a 9 speed echo-system. Cassette came from my turbo wheel...
Switched to mini V-brakes from the cantis, not much clearance on the 40mm Terreno Zeros.
Front hub was NFG, I grabbed a cheapo Quando hub out of the parts bin, painted it purple as an experiment (to see how the paint holds up) and rebuilt the front wheel.
It rides great, handles brilliantly, I am pretty happy with the outcome. Lots of naysayers about drop bar vintage MTB conversions, as usual many people just afraid of what they don't know.... Not a light-weight, all said and done as seen here 27 lbs 8 oz. The cromo frame alone is 6 lbs even. It was 31.5 lbs when I started (before as a mtb)... My target was under 28lbs, so all is well.
