This is probably a dumb question, but I can use some help on a problem. I just bought my wife a new bike with Shimano ultegra triple 10 speed components. Her former bike was Chorus 10 shifters & comp triple components . She HATES the Shimano shifters, especially since she has repetitive motion issues that is aggravated by the shimano shifters. Can I use Chorus 10 shifters with a Shimano triple set up? I've heard it can work, but not sure what problems would occur. Thanks for your help.
