Replace Ultegra 6600 STI lever

Question

I need to replace my Ultegra 6600 right hand shifter as the ratcheting system is gone. The rest of the groupset is all the same 6600 series.

I am having a hard time sourcing just a right hand side shifter and they cost more than I really want to spend.

I am having a hard time working out what shimano shifters are compatible. I gather there has been a change in the brake pull length, so its critical that I get a compatible shifter for the 6600 brake.

Will a Tiagra 10 speed 5400 combined shifter/brake lever be compatible?

Is there a compatibility chart for the brake pull options?

Any suggestions appreciated.

The Ultegra 6600 STI lever is available as a right hand only part. It should cost around $400 dollars for the right shifter only, and around $600 dollars for the set.

Any Shimano 10 speed rear shifter, including the new Tiagra 4600 10 speed will be compatible. If you have current brakes, and you use a 10 speed STI lever, as previously noted, you will have no problem with the brake pull.

The compatibility chart can be found here. Drivetrain Compatibility Front Drivetrain Compatibility Rear

Do you have a link to the diagram, it's a bit small to make out? – Ifor Mar 24 '12 at 16:11
It's a scan of a paper copy, so no links. – zenbike Mar 24 '12 at 16:27
I got a Tiagra 4600 shifter half price and its working nicely. – Ifor Mar 29 '12 at 07:38
