I just bought my first bike with Shimano STI Shift/Brake Levers. So far, I really like the feel. I cannot, however, figure out how to tighten the brake cables. I can find the barrels for tightening the shifter cables on the side of the shifter, but the brake cables go under the grip tape on the handle bars.
Bonus question: The smaller shift levers on both sides don't like returning all the way to their resting position, and require a nudge to get them back. As far as I can tell, they are just rubbing against the larger shift levers. I assume this is normal and that once I use the bike a little they will spring back correctly?
