I was going to bid on this. It has 126 rear spacing for 6 speed. Has anybody had a frame spread to 130? Will Serotta do it? Any idea to the cost? How about pitfalls in taking a bike that was built in 1984 and designed for 6 speed and converting it to 10 spd. It is on ebay if anyone else has an interest.

You can certainly go from 126 to 130mm by having the stays bent, but my opinion is that when you take a frame built decades ago and put modern parts on it, it just doesn't fit, meaning it doesn't look right to blend the decades. It would probably work fine mechanically, and if you don't care about these things, then go right ahead- It's a personal comfort thing.

I don't keep a late 70's Carter-era porn star sideburns and mustache look because it just doesn't work in this century. I'm waiting, however, for it to return.

If the sucker is NOS, it just needs to be built with the early 80s parts it was born for. Otherwise, it looks like the half-man insect creation Jeff Goldblum became at the end of The Fly.

Just my 2 cents.

like RM said, something about putting '00 stuff on an 80's frame that just doesn't seem right.....I'd put a six speed rear end on there with a big, old inside ring and go climb a 90 degree wall with it! I'm not saying I don't appreciate having that many gear choices but when I'm riding some of my 5-6-7 speed stuff what never ceases to amaze me is how LITTLE I find myself shifting!

I can respect a period correct build, but for all intents and purposes, when you have an opportunity to pick a steed from the stable, you won't likely pick the 6 speed with the straight stack 13/18 and DT shifters when you have another rig decked with Chorus 10 speed, Ergoshifters, and way better brakes.

I would update it to an extent. I have a buddy who is building up an older NOS Waterford. It is beautiful and 100% steel, including fork. When deciding how to build it, we came to a concensus that 10 speed would be the way to go, but not carbon. So, with a mix of alloy Chorus and Record parts, she will be done this week.

My opinion.... go ahead and hang some new bits on a great frame, just stay away from the plastic...er, I mean Carbon. :banana:

I've recently stretched a Bridgestone RB-1 from 126 to 130 by using a threaded rod (hardware store) with a couple of left-over wheel bearing cups, although I bet just good ol' thread on nuts w/washers would work too... you have to stretch a bit (I did 5-7 mm or so) beyond what you're looking for. Left it that way for a few days. I then mounted a 130 mm rear wheel for a week or two. Worked quite well, although remains a "little" tighter than a standard modern frame.

The Bridgestone (the original 1990 RB-1 with white/royal purple, and Ishiwata tubes and fork) will be built up with 9 spd Campy, all alloy. Well... still thinking about a black FSA compact crank. Shooting for first ride by the beginning of April.

Any good LBS can do it for you, too. Good luck!

Hey, I found the eBay posting.

I'd go for it.

Classic Serotta yellow and red colors (easily touched up with automotive paint from your local auto parts store), Colorado Concept tubing, interesting (fillet brazed?) and lugged bottom bracket, typical beautiful Serotta lugwork, and mint decals.

Wait... 55 TT, 55 ST... that's my size. Now look what you've done :D
