KMC X9-L Silver 9 Speed Chain: Having already made the worlds lightest 10sp chain (X-SL series), KMC decided to produce a new cheaper L version. Sharing a lot of the SL technology, the L offers both performance & budget. Symbolic for Speed: Made for any 9 or 10 speed systems in either Silver or Gold finish. Shimano or Campagnolo compatible Race proven, both on the road (TEAM ASTANA WURTH ) & Off Road (K2, Rothaus Cube, Trek USA MTB-team Benelux) we are pretty confident that our X-series can even satisfy the most critical rider. Our double X-bridge outer plate ensures maximum shifting performance, while our X-SP treatment in combination with precision tolerances prolongs the chains life to the maximum.
