Modern wheelset on older bike with 7 speed cassette and spacer?
Hi everyone,
I have a 1989 Cannondale 3.0 frame, with 7-speed Dura Ace 7400 groupset. It currently has a 7-speed freewheel.
My wheels are toast, and I want to replace them with cheap new wheels, like the Shimano RS010 wheelset (Shimano RS010 Road Wheelset | Chain Reaction Cycles). These wheels are not technically 7-speed compatible. Also, these wheels are 130mm spacing, and my frame is 126 mm I believe. However, that shouldnt be a problem, because I think the current wheel that is in there is 130mm as well, I just have to bend the dropouts a bit when installing the wheel.
Questions:
- Can I just use a 7 speed cassette such as this: https://www.amazon.com/gp/product/B007QTTYE6/ref=ox_sc_act_title_1?smid=A28Q2X8ZL50565&psc=1 with some kind of spacer, to fit the Shimano RS010 wheelset? If so, what kind of spacer do I need (online links appreciated)?
- Will the 7-speed cassette with spacer on a 130mm wheel line up properly with my rear derailleur when using it on a frame with 126mm spacing that was made for freewheels? Would I have to adjust my derailleur or would the alignment be identical to an old style freewheel?
Thanks!

You may need to adjust your derailer but you might not. Check before you ride.

I wouldn't relish trying to cram a 130 wheel into a stiff Cannondale 3.0 racing frame - the short chainstays were incredibly stiff, and you're putting a big load on the cantilevered dropout the 3.0 and 2.8 models used.
Why not buy a used 126mm wheelset of Craigslist? It would be cheaper and allow you to use your DA freewheel. 7 speed freewheels are still common, so you wouldn't need to worry about keeping the wheelset going.

Not a big load on those stays at all. Going from 126 to 130 is completely fine, based on my personal experience with literally dozens of Cannondale frames tha have been refurbished with 130 OLD rear wheels. You need a 4.5mm spacer for the back of the cassette, and it will line up just fine with your derailleurs. Should require only a slight adjustment to the RD, if any.
By 1989, many Cannondale frames were being produced with 128 spacing to allow installation of either 126 or 130 wheels.

I will have to measure my frame, it might be 128mm. If my current wheel is 130, I know it fits with pushing the chainstays outwards a bit, could be 2mm.

I have an '88 Cannondale and will need to do the same soon. I already have a set of 130mm wheels and intend to work the lock nuts and possibly the washers to reduce the OLD a bit. There is an old thread by miamijim on this with 7403 hubs.
Apart from this is my running 7 speed cassettes on my mountain bikes with 8-10 speed freehubs. I don't subscribe to the 4.5mm spacer per se. I will use the spacer width that gives me the best chain line (to the middle of the cassette). If it turns out to be a 3mm spacer I pick up the difference on the other side of the cassette. This may be too much trouble for most as the lockring side spacer diameter can get tricky, but it is an option that allows for less cross chaining and more usable gears when necessary.

If you are going to put a 7 speed cassette on the new wheels, then why not just replace the 7 speed freewheel on the old wheels? Or do you consider the old wheels worn out too?

Okay, yes you did say wheels are toast. Funny how things get changed in the head as you read down through all the posts.
