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!
