I need a little help with installing my new ultegra sti shifters (currently have the same ones on there) I don't see how to tighten/losen the part that actually goes around the bar. Also, are there any "rules" to follow as to how to rewire the deraileurs? ie always start with it in the smallest cog, etc. Thanks, I appreciate any tips!

There is a groove on the outside of the shifter body that goes down under the hood. Ues a 5mm hex wrench. Rear shifter should be in the small cog position when attaching the cable. Front shifter should be in the small ring position when attaching the cable. New shifters come with instructions don't they?
