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.
