I am trying to get back into cycling after a 20 year hiatus. I have a road bike I like a lot with Al frame, CF fork and rear triangle and 105. I am also buying an inexpensive hybrid for foul weather riding and trips to the store. The stock flat bar on the hybrid looks terribly wide for what I remember on my last hybrid and mountain bike. How do you decide on a right bar width? The mountain bike racers look like they are using wider bars than 20 years ago.

I used to like bar ends on my mountain bike. It doesn't look like they are common anymore. What do people think around putting them on a hybrid?

BTW, I'm a definite Clydesdale. 6'2" 280. (Down from >330).
