I got this today and want to learn something about it. The components seems older than the frame. The gearing is way too high, I’m a hill person. Before I do anything with it need to do some research. Any comments from those in the know? Thanks.

Looks to be a 1985 670.

Except for the Tires and the pedals it looks like it might be catalog correct.

As a hill person myself, I think you'll need to drop down to a compact double crank or swap in a long cage rear derailleur with a bigger cog set, or both. With those short dropouts, you don't have a ton of adjustment room to optimize your chain length to cog size ratio with he current setup, even though that NR RD is a lot more flexible than most people realize.

Very cool bike, though. Love the color especially. That old Concor saddle appears to be in remarkably good condition for it's age.

I think you got it right. Thanks. I checked out the catalog site you shared.

With its gearing it won’t get ridden where I live. The bike is in beautiful shape from being displayed in someone’s home for many years. I’m pretty new at this vintage bike stuff so not sure if it would be a shame to make it rideable by changing the gearing or leave it as is. I’ve been looking for a quality steel frame of my size to wrench on.

I trued the wheels on my Trek 670 last night. I was surprised how tight those white 700/23s were on the rims. I’m thinking 28s might fit.

Sweet — my size, great color. I have an ‘83 620 and a 520 from ‘84. Swap the crank for a compact and see how you like it. Keep the original — that bicycle is worth preserving as catalog correct IMO.

My suggestion would be take it some where you can ride it and do.... allot, that will tell you if you love it or just kind like it, if you love it don't worry about making mods, create something you will actually ride and keep the original parts. Vintage triple cranks abound especially ones that were put on MTBs so with a BB, Crank swap and a wider range FW you'll be crushing hills. YMMV. Also I have Mid 80s Trek 420 and 520s and they have triples to -stock SR and Shimano respectively

Regardless nice find OP.

My personal opinion-

First- and most importantly- it's a really cool bike. It's a great geometry, great combination of tubing and a cool color and a lot of the parts are excellent. It's also in really nice shape.

Second- This does not diminish from your bike- it's an almost 35 or so year old bike. This one, while in good shape, is not in "collector good" shape. IMO- that means it should be a great platform for you to play with. A classy bike with the parts you want/need on it.

If you're concerned about resale, keep the Campagnolo parts and put them all in a box together- you can always put them back on later.

If'n it were me... get a crank that'll do smaller rings- a triple if you're into those sort of things, some cool ATB/Touring derailleurs and a wider range freewheel. On the bar shifting if you wish (bar end shifters or the like).

While my Trek 400 Elance is WAY down the notches on the totem pole from your bike, I have it set up similar to that:

Sorta depends on the size of the hills. You might get away with simply changing out the big ring to a 50t and the freewheel to a 14-28t.

Neato bike and familiar with them, though don't know how whippy or what's acceptable to you - in that LARGE frame size.

If it fits and you like the characteristics of it, just swap the rear derailleur cage only to long type (aftermarket $35), change the freewheel and longer chain. Triplizer conversion for the crank and appropriate bb spindle.

As for the consumables, you might spend for cables, brake pads and nice tubes and tires, perhaps 700x25 Veloflex Masters skins. I don't think any 28 width will fit the rear.

Keeps it old school racer and ready for the climbs.

Didn't you buy that 620 from me? Red & grey? That was a great bike, I still have a picture of it on my desktop at work. Sometimes I wonder why I sold so many bikes that I actually really liked!
