STI upgrade success!

Lately, I've asked a few questions on this site about upgrading my '86 Shogun road bike to STI. Got different opinions and many helpful tips, but now everything is in place and I took it out for it's first test ride today. I gotta say, STI levers are the best invention since gears themselves! No more pausing to reach down to the drops to go for a shift! My hands stayed on the bars the whole time and every shift was a pleasure. Here's what I did:

Replaced down tube shifters with 8 speed 105 STI (ebay item).
Replaced 7 speed rear wheel with new Ultegra/Mavic Open Pro 8 speed cassette.
Replace non-index Shimano 600 rear Der. with new Ultegra.
All new cables
New SRAM Powerlinkchain.
Adjustments to everything.

Total cost-about $300.00

P.S. The old 600 der. would have worked, except for one thing-The geometry was such that the cage traveled farther per shift increment than a der. made for indexed shifting. It would jump two sprockets on some shifts.
Thanks for all the help!

Yep,derailer has to know how to dance to the right tune.But,why not 9 speed while you were at it?

The front der. worked fine with the STI.
Pokey, I knew I'd get asked that question, To make the story short, I bought the 8 speed shifters b/c I thought Shimano made an 8 speed freewheel. Thought I could keep my old wheel.
Of course, I could always sell the shifters on ebay and pick up a nine speed setup (and a new freewheel) but I'm a happy camper for now.

Coaster,
You can do fine with 8. The beauty of cassettes is that they are easy to pull apart and customize so you can make a combination that is exactly what you want. I would say you did pretty good for $300!
Regards,
Raymond

Well, SRAM still makes 8-speed freewheels (go to http://www.bikeusa.com/MERCHANT2/mer...FreewheelsSRAM )
If you want to go from a 7-cog to an 8-cog freewheel, you will probably need a longer axle, and will need to redish your your wheel, too.

Yeah,but they are campy 8 speed spacing(5.0c-c),which is close enough to shimano 8 speed(4.8) that it MIGHT work with an 8 speed shimano drivetrain.But why bother with 8 speed freewheels and the increased potential for bent or broken axels.

campy and shimano spacing to not mesh together too well. I have worked on bikes with it, and well, the bikes didn't work to well.
