Is there such a thing as 7 speed STI's?

[LikeClockwork]

If it helps at all, my Dad has some RSX 7 x 2 shifters to sell soon....unfortunately I don't have them here to take pics though...

RSX shifters have the brake and inner lever set up rather than the Sora set up which uses a thumb button vaguely like Campag.
I have some 7 speed RSX triple shifters if they are of interest.

Possibly interested...I'm guessing that they would still work on a double front setup? They work as they should? Any pics?

Thanks

Could be interested pending condition and cost! Let me know

Why not look for some of these http://www.lfgss.com/thread84305.html ??

Much better than Sora and the thumbshifters.

Shimano ST A070 are modern STI's that are for older 7 speed systems, if that's of any use to anyone.

...on another matter why is it that road STI's are soooo expensive looking at £70 odd for Tourney and if you want Tiagra £130....Dura Ace £250!!!!! MTB shifters look a bargain in comparison!

Manufacturer costs. They are so expensive because they are probably the most technically engineered part of a drive train, i.e the most moving parts, all tiny small parts that require high tolerances and high grade machined materials/steels, etc....my bet is they are the most time-consuming component in the drive train to assemble, with several robots and skilled human labor 'finishers'.

The older Campag (Mirage etc) 9 speed were less mechanical and thus you could get them cheap when new about 8 to 10 years ago, something like 69 quid compared to 140 quid for Tiagra. They could also be serviced and taken apart.

I don't think this stands up to scrutiny. The MTB ones have as many moving parts etc, and are much cheaper.

My theory, and I'm happy to be proved wrong, is that the developments in road bikes have to a certain extent been driven by the development of MTBs. I know materials have been developed over the last 30 years, but road bikes to me didn't seem to develop at much pace for the 40 years before hand. Yes there were developments, but not on the same scale.

Road bikes are still dominated by tradition, and the poor braking of calliper brakes is a case in point. They don't work well, but are still the standard. I asked on the road ride on Saturday, and after some shrugging was told it was because of tradition.

MTB had no tradition, and therefore better, stronger, cheaper, lighter products come through. Due to tradition, road parts now are better, stronger, lighter, but not cheaper.

Maybe it's because they are fashionable again now, and the demand is there, but I don't see companies like Tektro and the like making cheap knock offs that drove MTB parts prices down (although this might just be me being ignorant to them).

Forgive me if I'm wrong, and this is out of place. Just the musings of an idiot.

The other big factor is volumes. MTBs sell in far higher volumes (and stuff gets broken more regularly) which gives economies of scale - if nothing else then in writing off tooling costs.

On the original question - I don't know the answer but am about to find out. I bought a bike fully equipped with a virtually unused RX100 7 speed group except for the indexed shifters. Looking on eBay suggested eye-watering prices but I found some much cheaper on eBay France and will be using them. Counting the clicks suggests they are 8 speed but they seem to work after a fashion in the workshop. Road testing will tell but will have to wait for a couple of weeks.

As to the MTB price debate, above. Check out the prices of Shimano XTR stuff and I think you'll find I'd extravagantly priced too!
