Where does Shimano RSX fit in?(10 posts)

Where does Shimano RSX fit in?JimW

Not in the grand scheme of life, but in this scenario.
I've got a several-years-old Lemond Tourmalet with RSX parts. The bike and the parts are pretty worn out. I've recently come into a mix of brand spanking new Tiagra and Sora parts (and a 105 rear d.) My question is, does it make sense to replace old RSX with this entry-level stuff? Was RSX entry level back in the day?
Also, the Lemond will soon (with a little luck) become a backup bike.
Thanks for any input.

P.S. My first post. Hey.

if the RSX is 'worn out'.

The road lineup used to go:


Though it was definitely entry-level, there is nothing wrong with RSX. Tiagra would probably be a fine replacement. One thing to watch out for with a Tiagra/Sora mix is that Sora brifters, which are an inferior design in many people's opinion, are 7/8 speed, while Tiagra and higher are 9-speed.

At one time (pre STI days), RX100 and 105 were said to be identical except for the finish on the components, even though 105 was presented as higher end than RX100. 105 was more commonly spec'd on complete bikes and had a painted and clearcoated finish. RX100 was more of a bare aluminum finish.

RX100 pretty much got phased out as 105 followed the advancements in DA and Ultegra. RSX became more popular as a lower end choice. It was offered as 7 and 8 speed, and as double and triple. I think it never was 9 speed.

I think Tiagra is the equivalent level today and is 0 speed. Whether you want to upgrade to a higher level of componentry is up to you.

RSX was a durable workhorse gruppo that I'd submit was much better than today's Sora OR Tiagra. Still functioning well on many bikes from the early and mid-90s.

It was considered "entry" level in that nothing was below it on the Shimano food chain, but I wish we still had such a quality "entry level" option!
Agree--still works fine on my @10yr. old Allezretro

I've swapped the DT shifters for barcons just because I like them (the bike goes back to way before STI), but everything else on my early '90s steel RSX Allez is still working fine. I wouldn't swap until things start breaking.
Agreed. RSX seems to run forever. nmOldEdScott

My Cannondale R500 (1996?) has RSX all over it and I have never had a problem, but I did wonder where it fit in to the Shimano line also. Good to hear I won't need to be replacing parts in the near future! Always wondered when someone would remark about the long deraileur cage on my road bike (looks like mtn comp), but nobody ever has.
Actually, Sora replaced RSX, and Tiagra replaced RX100....theweasonator

If you recall, RSX was 7 spd and RX100 was 8 spd when the standard was 8 speed for Shimano. This kind of followed the evolution of 9 speed. When 9 speed came out, Sora came out as 8 speed (RSX and RX100 were discontinued) and Tiagra came out as 9 speed replacement for RX100.

RSX and RX100 are pretty good stuff. If you take care of it, it will last. I have RX100 shifters on my '95 C'dale R600 and the only problem I have had in 8 years (@13K miles) was this spring I needed new cables since I had ridden the same cables since I bought the bike.

RSX and RX100 are good stuff, I'd ride it till it falls apart and then upgrade it. But if you already have the Tiagra, it'll last a long time, just take care of it.

If you follow your logic that each group had a pecking order in the Shimano line, then yes.

But jtolleson and others said that RSX was quite good stuff in its day, and even by today's standards. It was only entry level in that there was nothing lower than it in the Shimano line.

Today's Sora stuff doesn't work nearly as well and many think it is less than entry level. I also think many entry level cyclists would soon outgrow Tiagra. But current 105 is really nice stuff, almost too nice for entry level.

My other point was that old RX100 and 105SC were functionally the same; the only difference was the finish. If you consider Tiagra the replacement for RX100, remember that it is inferior in function to current 105.
