Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

shifters forSshimano 7400 deraileur? change system cheaper?

I have an older bike that broke so I'm looking at trasfering all the components over to a new frame. The old bike was a triathlon bike with bar end grip shifters. They were odd and I never liked them. I'm changing it to road bars and sti shifters. I think the the older derailleur is a 8 speed shimano 7402. The 7400 sti shifters seem to go for a fortune on ebay. What shifters are compatible?

Would it be more financially savvy to just pick up a set of more modern 9 speed ultegra or 105 components? I probably should change the chain, rear cassette, and bottom bracket. Are those components going to be hard to find with the strange older 8 speed distances?

This RD is designed for 6/7/8 speed setups. The real "brains" behind indexed shifting is in the shifter and not in the RD.

The easiest thing to do is buy a new drivetrain for 10 speed, like 105 5700....or better yet even consider a whole new bike.

If you want to go on the cheap, you could buy 8 speed indexed brifters used off of ebay, or even consider indexed down-tube shifters (also from ebay).

There are many options. Nothing is perfect.

If you want to preserve as much of the old 7400 era drivetrain, you may wish to check out the C&V forum.

MicroShift makes 8 speed brifters. MS stuff works well in my experience, but I've never used the 8 speed stuff. Shimano 8 speed STIs of various levels and years are regularly available on eBay for under $100. Normal bar end shifters are readily available, or you could go with DT shifters. Lots of options.

Another option is to get a set of Veloce Ergo's (10 speed) from someplace like Ribble ($100ish including new cables), a Shimano Sora RD ($30ish), and hook it up with everything else current. Adjust out the last two clicks with limit stops, and you are good to go.
