Carbon Hybrid Handlebars
 

Seems to be limited selection for the road-oriented bikes. I found a Ritchey 710mm which can be safely cut to 630mm.
Looking into the end of the bar the thickness varies and is quite thin in one area. Is this a concern?

Being new to carbon I'm unsure if these are scuffs, or just the way that carbon appears:

Any thoughts?

If the manufacturer specs cutting down to 630mm then I'd send it.

They may break instantly. Especially the cheap ones. Be careful.

I've ridden on Carbon bars a long time, they are pretty damn tough and really help eliminate a lot of buzz in the hands. I would just wipe it down with some alcohol, it's probably just something to do with the molding process.

Follow up: The bars have been fine, aside from those ugly marks. I don't even look at those anymore, so...
A cheap-o tool from Amazon and a Park Tool blade was used for the cutting:

have a saw guide like that ... I believe mine is a Bikehand brand - could be the same tool (?) ... I use it more than my Park tool to cut bars

I have the Park Tool one and it makes cutting really easy. Use a fresh carbon-diamond blade in your hack saw.

Once I managed to crush the end of a carbon bar with a bar-end (despite claims it was carbon-safe). I decided the bar was a hazard and tried to break it with a sledge hammer (after I took it off the bike). It was impossible to break it with a heavy sledge hammer, but easy to crush the end by over-clamping. Such is the nature of carbon fiber.

Ritchey should be safe.
