RSX needed(14 posts)

RSX neededchuck1073

Tried searching the classifieds and found nothing so here goes.

Just wore out the right side (7-speed) RSX STI on my favorite old steel road bike. Does anyone have a replacement they'd like to sell?

I had a set hanging around, but just installed them on a guys bike in exchange for a project bike.

Something to consider. 7 and 8 speed Shimano indexes the same. The only thing they still make in 8 speed gear is sora. They do work fairly well and are fairly inexpensive, though admitedly not as pretty as your old RSX.

There is always bar-cons or downtube shifting....
John is correct. 7 and 8 index the same...Dave Hickey

You can put either 7 or 8 speed STI's(except Dura Ace) on a 7 speed and they'll work fine.
Nope...Rusty Coggs

Not the same,as 7 speed cog spacing is 5.0mm and 8 is 4.8mm. But close enough that it works reasonably well, although some say not well enough for them. . Don't use a 8 speed DA shifter unless you also have a 7 or 8 speed DA rear derailer to go with it.
I've had no problems using 8 speed STI's with 7 speed.Dave Hickey

But it's because the spacing is close enough,not the same.
I agree.Spoke Wrench

I actually have 7 speed bar cons with an 8 speed cassette on my retro grouch bike right now. It's OK. I'm satisfied with it for that bike, but I'd never let a customer's bike go out that shifted that poorly and I wouldn't tolerate it on my other bikes.

I've worked on several versions of 8 speed shifters with 7 speed cassettes too. My opinion is basically the same. It's rideable, but just not spot-on. Sometimes I have to play with the shifter a little to get the gear that I want.
I think you can still find 8 spd RSXjtolleson

through ... at least I did a year ago when helping a friend with a similar problem. Also, these pop up on eBay a lot.
Find an old Campy 8 speed shifterMR_GRUMPY

Shimano 7 speed spacing is 5 mm. So is Campy 8. Just lock out the last shift.
campy RD too? ....nmRusty Coggs

Sora 7 speed found!!!Lone Gunman
Jul 17, 2003 4:39 PM has both a left and right 7 speed Sora shifter @ $53 and $60. Since you trashed the right, get a pair and keep the spare RSX as a backup or sell it off.
Sora 7 speed found, part deux!!Lone Gunman

Loose screws has the set for $105 or $115 double or triple. sore dick deal, you can hardly beat it. I paid $100 for my RSX from Nashbar many moons ago.
