Yokozuna is a title; it is conferred upon the sumo wrestler who is the "best of the best." An odd name for a company that produces cables and housing. But on second thought, maybe not. Sumo wrestlers, despite their girth, have a graceful quality. Yokozuna Jet Lubed Shift Cables and Housing help your shifting achieve a graceful feel. -- In this case, the "Jet Lubed" name is to separate the shift cables and housing from the Reaction kit, which has both shift and brake cables and housing.
Though rumor has it that Yokozuna makes cables and housing for Shimano, Yokozuna is mum. We'd like to think these cables and housing are better than Shimano's, if for no other reason than we're loath to put Shimano-esque parts to work in conjunction with SRAM.
Yokozuna states that their Jet Lube Process injects grease into the entire length of the housing, not just the housing ends. How they do this, they're not saying. Yokozuna claims that the resulting shifting performance, when using their cables inside their Jet Lubed housing will yield 10% less cable drag than what you get from the competition. While we can't quantify what we've felt when we installed Yokozuna on our SRAM kit, it felt slippery; dangerously smooth. No lubing of the cable on installation, no need to lube at all.
The Yokozuna Jet Lubed Shift Cable and Housing Kit comes with the following: two 1.2mm diameter stainless steel cables 2100mm in length, two 600mm segments of housing, three 340mm segments of housing, ten plastic end caps, four cable ends. The color of the housing is black.
