Adding RSX STI's to my RSX drivetrain?(11 posts)

Adding RSX STI's to my RSX drivetrain?Skyeward

I just recently got a Bianchi Campione from a friend. My first road bike! WEEEEEE!!...Anyway, it has an all Shimano RSX(100) 7spd drivetrain, with indexed downtube shifters. I just got in touch with a guy who will sell me some RSX STI's for $40, and I was thinking this might be a good opportunity. He also has the rear derail. to go with them, but I don't think I need it. Here's my questions:

Am I right that I would only need to get the shifters, cables/housing, and cable stops for the downtube to make this conversion?

I haven't ever installed cables or shifters before. Is this a very hard job? Could I do it with the help of an online guide or should I just take it in to the shop? (I have Zinn's MTB book, but not sure how accplicable it will be.)

Are the RSX STI's any good? Is $40 a fair price?

Thanks a lot everyone,

You might want some new bar tape while you are at it, and some electrical tape to hold the cables in place on the bar when you have fitted the shifters.

It's a very easy job, and the price sounds very good for a quantum leap forward. I did exactly this to a bike a few years ago and it's well worth it for that money.

I just assembled RSX STI-s on one of my older bikes yesterday. It was Pinarello with downtube shifters and Exage 400EX group (7 speed). I bought these shifters for 40$ (they were used, but in good condition). You don't need rear derailleur. Just be sure that shifters you are buying are ST-A410 (7 speed), and they will work perfect with all 7 speed derails.

So, you need:
1. shifters
2. cables/housing (both for gears and for brakes)
3. cable stops
4. 5 mm Allen key
5. some kind of bike stand (optionaly - but tuning will be hard without stand)
6. new bar tape :))

Go to the There are an excelent on-line guides regarding STI-s assembling, derail tuning etc. If you like to work on your bike it will be very easy two-hours job.
I think that it worth 40$ (even more). I tryed them yesterday after assembling and found that they work fine - just as any other STI-s I already used.

that the 8's work as well - same spacing - unless you know different?

You are probably right... I never tried...igorn

In that case he can go for 8 STI-s as well...
I've done it. It works fine.. nmDave Hickey

thanks for all the help guys. I believe I'm going to give this a try, cuase the downtube shifters are the only things I dont love about this bike. Then I'll have bike that's smoother, cheaper, sexier, and way more "mine" than any superficially shiny entry level bike in the store.

I was just wondering: where did you guys get your RSX SIT's?

From a store, for lots of money (got a great deal on a used Dale R600 full 105 + shoes etc etc from a guy in my triathlon club) - like you, the only thing missing was STI - have never looked back (though have looked sideways - now more of a Campy fan, but there you go).

You won't regret it - it's the way ahead.

Enjoy - M.
I'v got mine in the local bike club...igorn

They changed complete group on one of their bikes and they had no more use for these STI-s. I think I was lucky...
Does RSX work with a triple set-up?cdlynx

I currently already have Ultegra on the 'great-weather' bike, and never really thought about adding it to my 'not so great-weather' bike which has 7 spd indexed shifting. Does anyone know if the RSX left lever is set-up for a triple chainring like current 105 and Ultrega? Sounds like others have made the switch to STI at a very reasonable expense. thanks, david

Shimano built an RSX 7-speed STI triple, if that is what you are asking. I recently upgraded a friend's 7-speed RSX triple to 9-speed 105/Ultegra triple, as explained in a previous post below. Her RSX left shifter was worn-out. Up until it quit it functioned well but I don't think RSX STI is anywhere near as durable as 105 or Ultegra.
