Please help me name this part.
Hey guys, just to start it off, i'm a newbie to road biking or biking in general. I just bought a CAAD9-6 and next to the gear shifters are little adjusters on the cable that connects the gear shifters to front and rear derailleur. My questions are, What are those adjusters for? and when would you use adjust it? Also, is turning it counterclockwise making it tighter like a spoke nipple?
I know this is a newbie question and i tried googling it but i could not find the exact name for that. Thank you guys for your help!
