RSX history lesson, please!(5 posts)

RSX history lesson, please!rohickman

When did Shimano produce RSX components? Also, how does RSX compare on the current Sora, Tiagra, 105, Ultegra, Dura Ace scale?

I am not sure how it compares to current stuff but I remember hearing that the first year it was produced as a 7 speed group on hybrid bicylces with a 26/36/46 triple crank and then the next year as an 8 speed group on road bicycles with a 32/42/52 triple crank.

I also think it then evolved into the RX-100 road group.

No, RX-100 existed before RSX. I had a Cannondale R400 in 1992 with 7-speed RX-100 on it. It was basically an unpainted version of 105.

RSX showed up a few years later as a mountain geared triple 7 speed group at the time when the better Shimano groups were 8-speed. My wife (then girlfriend) bought a Specialized Allex with this group on it. It was not as high quality as the RX-100 group. It did have STI shifting.

If you're looking at the 7-speed version, I'd pass. The front rings are too damn small for road riding. You run out of gear really fast.

It's roughly the same as Tiagra. On the scale you gave, it would be bottom-rung, just above "Shimano SIS" badged junk on K-Mart bikes.

I bought a RSX bike in January 1995. It was the first year that RSX was available with SIS (not sure if RSX existed prior to this or not). I wanted a bike with SIS, but could not afford a 105 bike. When RSX was introduced I bought it.

It was 7 speeds in it's first year. The rings were standard (i.e. not compact) MTB rings. I forget the exact size 24/34/46 maybe? The previous post is correct that in the hills you run out of high gear real quick - anything remotely near 40 mph became a drift.

RSX was one step below 105, and would be equivalant to Tiagra today. However since it was 7 speeds instead of 8 (whcih was the standard of the day), it might be considered somwhere between Sora and Tiagra.

As far as the actual function goes, I switched to Ultegra directly from RSX. My inital response was, "I paid $500 for this?" Other than having more gears, a much higher top end, and a lighter bike, I could not tell a huge difference in function. However, I've riden a few Tiagra bikes and I think the drivetrain is really loud. Maybe if I switched back to RSX I'd notice the noise (Ultegra runs quiet).
