I had a 979, though I ran it with DT shifters I did switch another bike from DT to Ergopower. You'll need adaptors for the DT shifter bosses to run the cables on up to the brifters. Make sure the index pitch on your cassette matches the shifters.

I had an American Classic seatpost I was lucky enough to score at the same swap meet I got the frame

Yes, bare aluminum will oxidize. You can try waxing the part of the rims between the spokes to slow down color change, but I wouldn't wax the braking surface.

Kalloy seems to be the brand that makes various sized seat posts. You could try ebay.

You will require down tube cable stops in place of the current shifters. Are your shifters brazed on or are they on a clamp? Could you please post some up close photos?

Run a continuing search on eBay for 25 mm seatposts, they turn up from time to time. Or someone here may have one for sale.

The frame cannot be spread to 130 mm dropout spacing, and it is not a good idea to force a 130 mm hub in there. So you are limited to 7 speeds, and likely a freewheel. I'd measure cog spacing and then look at the link below to figure out what combination of brifter and rear derailleur might work. I don't know if Shimano made a brifter for 7 speed that doesn't look awful.
Rear Shifting | CTC

Polished aluminum oxidizes over time, but you can keep it shiny with just a little occasional polishing - look for products made for polished aluminum car wheels.

1) Convert the DT shifters to brifters.

2) Polish the frame.

3) Install a seatpost Reading up it looks like I will need a 25mm diameter seatpost. Thanks!
1) I converted my '92 to 10 cog from 7 cog Shimano two years ago, quite straightforward. I used DT controls to retain the feel I'm used to for 20 years of service but 'brifters would just require thread on cable stops. The most important thing is to match the generation of indexed drivetrain to the rear spacing. No problem w/ a 130 rear hub in mine but the 979 frame Cannot Be Coldset so measure carefully before investing in components.



2) The scratches are Patina, clean it and ride it. The anodizing likely will not benefit from polishing and will be a bear to mess with.
Any serious attempt at finish work w/ chemicals and power tools will likely result in an ugly mess. I'm not w/ the Period Correct Police but just live with it.

3) 25MM is correct. Be careful not to bugger-up the seatpost binder/stud.

126mm 7s HyperGlide freehubs exist. 8, 9, and 10s cassettes can be used if the appropriate number of cogs are removed. (Remove 3 cogs from a 10s cassette)

A 130 mm 8/9/10 rear wheel will probably slip right in with very slight outward pressure, and work fine. You need to try it, and test cassettes with different size cogs to make sure that the chain will clear the chainstay.

I'm running a 130mm wheel on a 1990 Trek 1100 that came with a 126mm 7-speed freewheel on the rear, and have test fit a 130mm rear wheel on a 1997 Trek 1400 (came with a 7-speed cassette), and a 1988 Trek 1000 (came with a 126mm 6-speed freewheel).

I'll admit that this is a small test sample, but it shows that 130mm rear wheels will in fact fit onto aluminum bikes with 126mm rear dropouts without a problem, which is what I read on BF many times before I tried it.

Out of the saddle climbing can cause ghost shifting , as the frame does flex.

A 7 speed screw on freewheel on a 126 hub will work OK , as will a 6 speed too.

Yea dont polish off the anodizing , do frequent detailed inspections for fatigue cracks in the aluminum.

Thanks. Yeah I will leave the anodized finish on. I am now just looking for ways to touch up the scratches.
Re the freewheel, do you know if this will work?

7 cog Shimano in any flavor will work/index/fit just fine.
Unless you have a good threaded hub for FW I'd go cassette 126, a much better system.

Have fun, enjoy and post pics after the conversion.

Mine never has "ghost shifted" in 22 years of service racing it as hard as I could push it and putting on lots of club ride miles.
But I'm not heavy or awesome.......

Unless you've spent saddle time on a 979 and experienced the Ghost yourself it's an Urban Cycling Myth.

Working on all the parts for my 979 as well. I'll be sticking to DT shifters, though and 7 spd. Will go with a Kalloy seatpost. While not the prettiest they are reasonably priced and work well (had one on another bike.)

I find hyperglide stamped teeth are very prone , to jumping, older tall tooth much more secure.

Ghost shifting, no.
Twitchy descents, yes. And still my third -favorite ride in the fleet.

Mine ghost shifted, no myth. But it was a large (60 cm) frame, which may have exaggerated the problem. I didn't think it was flexy at the time, but now I ride a modern steel bike, and the difference in stiffness is huge.

Beautiful! You might consider some tan sidewall tires if you want to have a more classic look.
