Ultegra STI shifters/brakes removable from handlebars
I am switching my stem and handlebars to something lighter - I've got the torque specs and feel comfortable there. The bike has Ultegra STI 10 speed shifters/brake levers - after removing the tape and peeling back the hoods I see that an aluminum clamp is attaching/holding the shifters to the bar. What I can't see is how is this clamp loosened or tightened. Any tips? Also when attaching the shifters to the new bar, any tightening guidance to make sure I don't under/over tighten? I looked at the Shimano site - didn't see anything (not that it's not there). Any links to diagrams?
