Show Us Your Vintage Cannondale!

Cannondales have stiffer chainstays than most steel frames but they will still flex easily enough to accommodate the wider hub. I did the calculation once, as someone had posted some fear-mongering link off the internet suggesting that bad things would happen if the dropouts were not realigned. IIRC, assuming the dropouts were perfectly straight to start (unlikely), they'd sit at ~0.5 degrees after being stretched. If you can eyeball that, you are better than me! As noted already, don't even think twice about it. It will be fine.
I can't let a question go by about going threadless on a vintage frame without commenting, or at least inserting a pic. Below is an SR500 I built up on a budget using some Mavic wheels (early 2000s but Mavic got lucky and made them with a freehub that accepts modern 11 speed cassettes) and Shimano 105 5800. The headset is something I designed allowing threadless stems to be cleanly fitted to threaded forks. These old fat-tubed Cannondales work well for this type of conversion, in my opinion. I left it uncut for this pic but the stem can be 'slammed' down on top of the upper bearing or fitted with up to 50mm of spacers as shown.

39-28 is tough but manageable on the hills I have around here. The capacity is a bit more than the RD can wrap, the chain might sag a tad in small-small, but I don't ride like that of course.

Shimano 6400 parts. FC-6400 53/39 crank. Hub is the 126mm freehub 7-speed that accepts both uniglide and hyperglide cassettes (FH-6401 I think). Cassette is a new HG-51 8 speed 11-28, but I'm not using the 11, so it's 13-28. I needed a 1mm cassette spacer as well. Also using 8-speed shifters (SL-6401) to match the spacing on the cassette.

1988 sr500
This bike has been with me a while now. Picked it up at a swap meet in Chicago about 10 years ago. The original wheels were gnarly and it had lots of worn out components. I worked at a bike shop at the time, so I had help making it rideable with some donor parts... It looked appropriate for a broke 20 year old, rampaging around the city.
Finally decided to give it the love it deserves and dress it up. Very sentimental bike to me because of all the adventures. Usually very fast adventures, it doesn't do slow very well.
Still waiting on some parts, but most came off of a CAAD 9 I'm not riding at the minute. Brown bar tape, pedals and a new saddle should make it feel loved 🥰🤣

It might be wrong, but it could be oh-so right. Just playing with spare parts and this frame, though I won't do anything irreversible.
Gonna be, at least for a little bit, a 2x1. 53/39 by 16
Sort of a pseudo TT bike, but I'm guessing the geometry will never be perfect for that, other than being a little undersized for me. Just gonna have fun with it.

I also have a trimmer saddle that would look better here. The 2x1 setup is just for kicks, not a lot lighter anyway due to my use of an old derailleur as a tensioner. The single speed tensioner I have doesn't have enough capacity for the 53/39 chainrings. I just wanna ride it and see how it does. If I frickin' love it, I might leave it like that for a while. If not, I'll start to find parts to get it back to something sorta similar to its original configuration, though with a somewhat wider cogset range than it originally sported. Probably stick with the downtube shifters (already have the front one working fine), and if I go back to a fully geared drivetrain, may still keep the bullhorn bar. We'll see. This bike doesn't really fill a 'need', so it's purely experimental. I do kinda take a fancy to the idea of using it to pick up a KOM or three.

My winter project, finished early. Wanted something that would ride completely different from my steel bikes. This one's a '98 with a parts-bin build. Built to be light and fast, which it is. Got a few rides on it before the snows set in--stiff but not harsh. I like it, but my favorites are the Black Lightnings with Superbe Pro...

in what was possibly the dumbest thing I've done recently, I got a 1986 SR600 from a guy at the homeless shelter next door for 250 (he offered 200 which seemed like a ripoff)



Replacement rims need to go, some of the bearings (particularly the pedals) are in rough shape but the majority of the parts are original.

Hi zachleft
It's a 90's Criterium frame. I used generic paint stripper and then wet sanded everything, then finished with Mother's aluminum polish. Took me a couple of hours spread over a few winter Sunday's. Final step was putting Bike Lust on it. The frame's been sitting in the garage (gotta get it on Ebay one of these days) and isn't showing signs of outrageous oxidation.

H400 from the co-op's dumpster, missing hanger and with broken cable guides. It hung indoors for a few years and they finally got rid of it. This would make a nice project for someone who fits it. I won't be hanging onto it but I could not let it go to the dump or recycling.

Some more H400 pix. I assume all the missing stuff is available.

Needs a seat collar and cable guides.

I remember those early stainless hangers with the thin sections sandwiching the frame's dropout.
