Dong, I am pretty sure you will need a new wheelset as the unique is 27".

Here's what you are looking at:
9-speed chain (I like SRAM)
new wheelset and 9 speed cassette.
new tyres and tubes (I recommend 700/25 clinchers, a bit wider for comfort)
new brakes (I recommend dual pivot, but you will need a 'nutted mount' set as you have an older steel frame)
your 9-speed STI shifters
any newer square taper crankset (I recommend a 50-34 or 50-36 'compact')
I am not sure about the BB threading on your Lotus, but once you have it determined, then stick a square taper cartridge bottom bracket in there too.
your front derailer might well be OK, give it a good clean and regrease.
same goes for the rear mech, funnily enough. I think it has the correct pull ratio. But it will almost certainly need a good clean and overhaul
new brake and shifter cables and housing.
Bar tape.
Down tube shifter boss adaptor for STIs

That should be enough to get you started!
Best of luck

If you have the parts, you can start, but if not, that's quite a conversion.
Not hard to do, but you're replacing everything but the frame (done it, like it, but know what you're getting into)

The others here are right, all the parts should fit.

1-a little oomph is required to get that new wheelset into that frame.
2-you may have a clearance problem with that outside cog. When the chain's on it, it may rub the chainstay, and need a washer.
2a-if you put a washer on the R end, your dish is off the thickness of the washer, generally not a problem, and not with adjustable dual pivots.
2b-if you put a washer on it, this can make removing/installing the wheel "interesting," but not an obstacle.

Since you're putting an all-fresh group on it, I see few other problems. Other folks noted the DT cable stops.

Very cool color scheme! Looks like a champion!

Back in September 2010 I posted in this thread by accident when (as someone who had only recently returned to cycling after a 17+ year hiatus) I didn't know what "Ergo/STI" referred to. Since that time I've become more familiar with modern "brifter" technology and have been contemplating upgrading my early 1980s Ciocc San Cristobal (pictured below). I'm not very keen on cold-setting the frame from 126mm to 130mm though since I wouldn't be able to ride my old Campy Super Record/Mavic GP-4 sew-up wheels. I just wish that there were after-market brifters specifically made to work with old school 6/7 speed freewheels and derailleurs. Any thoughts/ideas/suggestions? Thanks!

MrEss

I haven't done it myself, but word on the street says that Shimano 7 or 8 speed STI will work with Ultra6 or 7 speed freeweels; you'll have to set the derailleur limit stop appropriately and there'll be a useless dead click at one end of the range.

Bikedued

I did it, and it worked fine, with Shimano of course. 6-7 use the same chain, so that's easy. Recently I ran a set of 7 sp Shimano STI's on an eight speed cassette, without even thinking it might be too different. Worked VERY well! Stands to reason it would work the other way around. I have a question too? Does anyone know if the cable pull came first, or was there a total redesign of Shimano RD's once they started indexing? I am about to tastefully update my Trek 600 6 speed to 7 speed STI's. The bike is friction shift, but I cannot tell any difference between a 1st gen indexing 600 RD I have, and the RD on the last gen friction only 600 RD Trek. I was hoping for the best, but if anyone has pulled it off without a hitch, let me know?,,,,BD

The sprocket spacing on 6 and 7 is the same. There are 7 speed brifters but you would need to find used and they are getting rare. I am not aware of them still being available new unless you luck up on some NOS somewhere.
The 8 speed cassettes are spaced a little different but 8 speed brifters will work on 6 and 7 speed Shimano Freewheels and are easier to find. They had a good long run from early 90's till current (lower end bikes running Sora level components). When you adjust your derailleur it will limit it to shifting how many gears you have. Some older Shimano derailleurs will work even though they were not specifically indexed shifters but you would do best to match. There has even been some reports of Suntours derailleurs as well as Freewheels working but there is no list of what will and will not work it is going to be trial and error.

The easiest thing to do is by a matched group or buy a donor bike with a the complete parts you want. I have picked up 2 low mile donor bikes with complete 105SC 8 speed groups cheap in the last few months. One was $125 (sold the nice prestige frame for $60) and the other was $70 (may clean up and flip). Now I am having to disassemble and clean the Brifters. With age the grease dries up inside them and they get stuck. There is a guy that runs a well thought of business fixing this problem. He often runs deals on Ebay
I believe this is him:

You can run Campy 8s Ergos...but...you will need to run a modern Campy RD.

tugrul

+1 Standard 5mm 7 speed drive trains should work with Campy 8 speed ergo + derailleur or Shimano RSX ST-A410 or Sora ST-3303-7 and Shimano derailleur.

Those are the straightforward ones. Then there are the fractional modern setups on a hyperglide hub.

Been riding my Schwinn Traveler for a few years in this form:

That's a real good looking bike in my eyes.

Zillon

Thanks!

I'm really happy with how the whole group came together - and how the modern Hollowtech crank looks on the bike.

I went back and forth on the silver bar tape, but I think it really ties the whole bike together.

Bikedued

That group looks like it was made for that bike! Nice job!!,,,,BD




I put a nine speed STI group on a Super Le Tour 12.2 and had one problem. When I stood to
sprint, the FD would rub slightly on the chain. The stays flexed I guess? Overall though, it was an amazing transformation! It literally rode like totally different bike. Modern wheels and drivetrain
is a lot of the enjoyability I imagine. I can't wait to build another one like that. The old frames
are just look SO much more classy looking.

rat fink

Very excellent! I'm surprised how finished that looks.

The saddle on my Pogliaghi is a Selle Italia SLR . Some of my friends say i straddle an ironing board, but i swear this little saddle is very comfortable. Its probably good to keep in mind that im a tall and skinny dude. i could see how someone thicker than me might not care for this saddle.

stausty

I toyed with the idea of making Campy Ergo's that were compatible with any shifting system you could dream up. It all comes down to the spacing of the clicks in the shifter so there's no reason (assuming enough cable pull) you couldn't move the clicks around. Ergos would work better since they're easier to get to the right part in the shifter. Shimano would work on the same principle, I assume, but I haven't worked on them. You'd need to know where to put the indents, obviously, and really a CNC mill to do the job correctly.

If you knew the right specs there's no reason you couldn't make an indexing system out of a set of Ergos, a hyperglide freewheel, and, say, a Nuovo Record derailleur if you wanted.

sounds like a good project for you. Please make sure you do a writeup

I love that bike. Miyata was really ahead of the times with their paint and graphics in the late 80's/early 90's.

Hard to imagine that's an 18 year old bike. I like the frog stem and white wrap. We'll have to ride soon.
