KMC X10-L Silver 10 Speed Chain Twin Pack: 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. 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. Made for any 9 or 10 speed systems Shimano or Campagnolo compatible NON-Directional Design: assembly of this chain is independent of direction. It allows maximum compatibility with MTB or road X-bridge outer plate ensures maximum shifting performance X-SP treatment in combination with precision tolerances prolongs the chains life to the maximum Open Inner plate reduces weight & reduces the chance of chainsuck
