I've got Competitive Cyclist to thank for the introduction to Yokozuna Reaction Cables. It wouldn't be the first time they've steered me towards great gear and these amazing strands are certainly a $65 bargain compared to the Cervelo they "persuaded" me to buy.
Back in September, with two centuries just around the corner I made a few changes to both bikes and took the opportunity to replace the stock Campy cable set on the Enigma with the Yokozuna Reaction product. While I can imagine that cables experience some quantifiable degradation in performance over, say 10,000 miles, I'm sure it's not much (and most of it could be remedied by an appropriate retensioning). Regardless, I wanted to see if I'd get the same quicksilver response that CC suggested and I haven't been disappointed. Shifting and braking are crisp, immediate and essentially frictionless.
My only quibble is a visual one. I love the spriral wrap of the compressionless brake housing, and though I understand that construction may not be necessary for shifting, the shift cable looks decidedly pedestrian by comparison. I doubt this will change if packaging is any indication... Yokozuna doesn't seem interested in competing with the Italians (I love Campy packaging). Then again if CC sells a ton of these, Andy may have some creative influence. Need some new cables, give him a call... the Reactions are available for Campy, Shimano and SRAM.
