26.0 or 31.8 will make no difference for most riders - I have both. 31.8 does look a little more "pro", and goes better with oversize tubing.madonna said:Hi guys. Me thinking of changing my current 26.0 handle bar to a carbon one. Wondering if it is more advisable to get a 31.8 handlebar which looks more pro.

Carbon bars are another story. I tried the original Easton EC-90 (in 26.0 diameter) several years ago and they were OK, but a bit flexy. Now that carbon bars are 2-4 times the cost of lighter aluminum bars, it doesn't make sense to me. Those who claim an improvment in shock absorption have a vivid imagination, IMO. I logged plenty of miles on gravel-sealed asphalt and really didn't notice a difference.
