On MTB rides, I always wear a chamois under-short with baggies over. I'm all about the padding.

A friend has loaned me a road bike to start riding pavement from time to time and much to my amusement, I really like it! But what is up with the bibs? All the roadies seem to use them as opposed to just shorts. As much as I love new bike stuff, I'd like to keep things consolidated on the clothing front.

Is it worth it to get a bib for road rides?
