A few follow-ups if you don’t mind. You said:
10 speed ultegra shifters won’t work with an otherwise 9 speed group. But then said: A 10 speed shifter(6600) will probably work reasonably well with 9 speed derailleurs, brakes and cranks; if the cassette and chain are 10 speed.
So 10-speed shifters will or won’t work? Those two statements seem contradictory. Are you saying the shifters would work if the cassette and chain are 10 speed? Even if the derailleurs are 9 speed? So the rear derailleur just wouldn’t be able to get the chain into the last gear? That seems like a poor solution.
Shimano r-600 shifters are shorter reach but Ultegra level and still available in 9 speed
What’s the deal with Shimanos R-600 stuff, I have seen R-600 compact cranks and now you are mentioning R-600 shifters. And what do you mean by shorter reach? This seems like the best option if there is nothing I am failing to understand about them.
Thanks for the help.
I just had to change from a set up like this.
Without getting too deep into how the derailleur-shifter setup works: The 10 speed shifters will work with your 9 spd setup but only in a small range of the gears. That’s because the index shifters for 10 gears makes the derailleur travel a few thousanths of an inch less than 9 spd shifters. You can tune it to a “sweet spot” that will work fine, but outside of that, the chain starts to make noise and doesn’t track well. 9 speed brifters apparently are discontinued. Thus you have two options: get lucky and find someone online that still has stock, or buy a cheap wal-mart bike just for the brifters. (yes, I’ve heard of people doing this)
If you end up with 10 speed shifters, it’s livable. You’ll have to stay in the sweet spot, but then some riders never get out of particular gears.
R-600 is a set of pieces from Shimano that a basically low to mid end, and typically meant for OEM bikes. They’re known as “non-series”. You can still buy them brand new, and they’re good quality for the money. If you can find them, they’re probably the least expensive solution for you.
Me? I chose to bite the bullet and I went full Ultegra 10 speed all around. Cost me about $500, but worth it.
