Lost a screw on the ride this weekend, it is this one:
and removing the silver cover it looks like this:
This is my bike and assuming I’ve got Ultegra ST-6800 pulled up dealer’s manual from here: https://bike.shimano.com/en-EU/product/component/ultegra-6800/ST-6800.html
and quickly scanning didn’t find any info on replacement. I’ve got a call into local bike shop… should I just remove the other screw and go to LBS or hardware store for replacement?
