I have a 2009 Easton Monkeylite XC Carbon Handlebar that I want to put on my Pivot mach5. The stem is currently a ritchey Pro stem. The 2 front brackets of the stem have areas of raised grid pattern for friction. I'm wondering if I can use this stem with the carbon bar. I ask because the directions for the bar go on and on about sanding down any burrs on any pieces (stem, shifters, brakes) that are bolted to the bar. So can I use this stem with a carbon bar? Should I switch stems to one that is smooth on the surface that touches the bar? Thanks for comments!
