I'm old, fat, slow, and stoopid. I'm certain that this will be difficult to believe but even so I've figured out how to use brifters, install, adjust, and maintain not only one but several 3x9 drive trains. I know - amazing innit ? The downside is that Ultegra is so solid that I forget how to do it between times that it's necessary. I understand that 1x people get lots of practice. Must make it a lot easier for them.
