Bashley, your bicycle appears to have the matching New 600EX shift levers. (It definitely has the New 600EX crankset and brakeset. The pedals are replacement ATB pedals, though it possibly may not have been spec'd with New 600EX pedals as part of a cost concession, as it does not have the New 600EX headset. I can't tell if the hubs are New 600EX). The 600EX Arabesque levers have extensive embossing on the top (see pic) and do not have the upturn/whale tale at the end of the lever, which I see on yours. The New 600EX shift levers have embossed ridges running along the outside edge of the underside of the lever, to aid in gripping the lever.
