Upgrading Old Bike(5 posts)

Upgrading Old BikeOkieDokie

I have a 1990 Cannondale Pro Series road bike with Shimano 105 components(6sp, downtube shifters etc.) In January I got the bug to ride again after a 6 year layoff. I would really like to get into the 21st century with my components and upgrade to Ultegra STI. What, if any problems will I encounter attempting this upgrade. Any modifications required. Any help appreciated.

Three points:

Your 6-speed Cannondale has 126mm spacing between the rear drop outs. To upgrade to 8 or 9-speed you need 130mm. 4mm may not sound like much, but the general consensus is it won't work with an aluminum frame.

Even if the spacing wasn't a problem, there are some serious cost considerations. New crank, bottom bracket, STI levers, front derailleur, rear derailleur, chain, cassette and rear wheel are all necessary. The least expensive way to buy all these components at one time is bolted onto a new frame.

If I havn't discouraged you yet, consider this. After you do all that, and spend that much money, you still won't be really styling because you'll have an 11 year old frame. By all accounts the newer Cannondale frames are significantly better in every way. Threr's lots of other choices too.

If you buy a new bike you get every single part brand new. Every single part is designed to work with every other part. You'll get a better, more modern frame and a new bike warranty. Cost won't be much greater than upgrading your present bike.

I always like the idea of keeping old bikes alive, which is why my garage looks the way it does. Still, upgrading probably doesn't make sense, for all the reasons Spoke gave.
If what you want is a bike to RIDE, though--hey, ride that one. It's a solid frame, probably works pretty well, and it will take you anywhere you want to go. Or keep it as a rain bike and buy something else to ride in summer.

If your trying to get better performance then a new frame is the ticket any way. This may not seem intuitive, but you will not save any money by trying to upgrade a bike that old. Look for a 2000 model that is collecting dust in the corner of the bike shop, or if you are sure of your sizing then look around on line.

I agree with Cory (and the other previous posts, as well). If you're looking to get out and ride, maybe do a few non-competitive centuries then just ride what you have. For This reason, I picked up a late '80's/early '90's Trek 2300. It's 6 speed, downtube shifters, single pivot brakes & it *works* great. I'll do about 8 or 9 centuries this year on it as well as many miles of just general riding.

However if you're looking to be competitive then financially I'd go with Spoke Wrench; Buy the whole shootin' match new. On the above-mentioned ride, with all the "little" stuff I've done here and there over the last year and a half, I could have had a Jamis or Univega or Schwinn, had the STI 9 speed, dual pivot calipers and a lighter frame.
