After many months of use, and many miles of abuse, the X10SL has been worn faster than the X9SL, but both have lasted significantly longer than their predecessors. KMC has improved the SL series’ technology to increase the life of the chain, which is an excellent accomplishment when dealing with a lightweight chain in such a demanding and inhospitable environment.
The KMC SL chains are lightweight, shift well and have a usefulness duration that is better or comparable to other lightweight chains on the market. I still would get an occasional ghost shift, but it was nothing that created undue functionality. The technology and innovation that KMC has used for the SL series chain will keep them at the forefront of the chain world.
KMC continues to tweak and massage their chains using their expertise, so they are always upgrading the XSL series so that they can bring the best and highest performing chain to the marketplace.
And of course the gold version is bling, and really seems to shift better!
