Campagnolo Chorus™ Ultra Narrow™ 10s chain is just 5.9-mm wide. These new dimensions make it lighter and more silent and facilitate adjustment of the rear derailleur. The links have been lightened so that the chain weighs only 269* g in all. The tests run in our laboratories show that traction force, pin retention force, wear and resistance to stretch, torsion and flection are the same as for the Record™ 10s chain.
