It’s hard to imagine that Shimano could improve upon the shifting performance of the Dyna-Sys 10-speed chain, but with the CN-HG95 XT 10-Speed Chain they’ve managed to reduce friction by roughly 60 percent. The CN-HG95’s directional/asymmetrical plate design allows the chain to glide effortlessly across cogs and chainrings, respectively. The new Sil-Tec surface treatment provides a quieter and cleaner ride while also increasing chain life.
