Search all the different bike forums, lots of threads discussing bibs.

I did take the time reading, since the difference in riding comfort is greatly influenced in clothing choices. As for bibs, I believe the biggest issue for most people is the straps. Take two people, both weighing 200lbs with an 36" waist. One is 5' 8" inches and the other 6' 2", and according to the size chart, both need the XL. Except how can the same size bib fit both people equally with a 6" height difference? I think here in lies the problem and why some people either love or hate bibs. Depending on the manufacturer, the bib material and cut, strap lengths vary and it's very important to find what works for your waist size and height. Read the reviews and see what others are recommending for your body size.

As for me, I'm 5'8" and have bibs from 3 different manufacturers. The difference in strap comfort is not bad since I'm not very tall. One is perfect, another loose and the 3rd is between the first and second. For someone taller, they're going to view these bibs differently.

Unless you can find bibs locally, your taking a gamble buying off the net, so read reviews and look for a good return policy.
