Yokozuna Reaction Cable System

Yokozuna Reaction Cable System

The Yokozuna Reaction cable system should be considered an upgrade to any shifting and braking system on any bike, regardless of the component system. Most of the time, we recommend sticking with the manufacturers OE spec for replacement parts and more often than not, we find an 'upgrade' can ironically cause a reduction in performance. This certainly is not the case with Yokozuna cables and housings. To better understand this product, you need to break it down into two distinctions: shifting and braking.

When trying to improve your braking system with cables and housing, the idea is pretty simple, reduce friction between the cable and housing while reducing compression in the housing. Seems relatively simple, but is hard to achieve without the proper tech. The Yokozuna housings have what they call RapidWire Compressionless Technology. The way the housings are constructed and wound, truly provide the industry and riders with the first housing completely void of compression. Doing so permits perfect cable response with great linear feel. Both braking power and modulation are improved. The lack of compression also greatly reduces friction due to the cable having a stout/compressionless piece of housing to move through. The cable is constructed from high-grade stainless steel and are tightly wound causing them to be somewhat strecth-less - a perfect complement to the RapidWire housing.

Shifting is taken care of by Yokozuna's Jet Lubed housing and cables. The 'Jet Lubed' process injects the proper amount of grease throughout the housing, not just on one end(or not at all) like other manufacturers. The housing itself is stout and high quality, while the cables are, like the brake cables, top shelf. Tightly wound and made from the best stainless steel available. The result is a giant reduction in friction - the number one culprit in decreased shifting performance. Yokozuna claims 10% less friction, we claim this is an understatment - they are a marked improvement.

Considering how much gained improvement you find vs. the cost, we highly recommend giving these a try. Available in Shimano/SRAM or Campagnolo. Full derailleur and brakeset, end caps and ferrules included for one complete bike.

    I'm using this with a Campagnolo 10 speed set up. I have noticed no real difference in braking or shifting over Campagnolo cables. The housings were difficult to set up with 3T Ergonova bars due to their inflexibility. The rear brake cable is now binding after 6 months, something which I have never experienced with Campagnolo cables. I'm going back to Campagnolo.

    Pros None.

    Cons Inflexible housings, binding rear brake.

    After reading all the positive reviews, I was excited to get this product to replace my old SRAM Red cables. However, I was very dissapointed with the end result. First, the cable housings were very difficult to cut. After multiple tries, I could not get the breaks to stop hanging. Finally, I gave up and discarded the Yokozuna break cable housing and went with a much less expensive brand housing. This solved the problem on the first try. The shifter cables work fine, but I can't tell the difference from less expensive brands.

    The Yokozuna brake housing will cut fairly easily with a good pair of sharp cutters. While not hard to install, they will require a little bit of bike maintenance experience.

    Cons Expensive and impossible to work with

    Its a nice set, but the extra stiff housing can make for a tricky install if you are dealing with tighter bends or internal routing. Braking and shifting do feel better, but Im not sure its that much better than a nice set of Shimano or Campy cables could provide. Id give it 4 stars but the brake cable ends are non-standard and wont fully seat in SRAM Red shifters.

    I installed these in the spring and at first thought that they were not worth the extra money. I didnt notice any real increase in braking or shifting at the time over other cable sets but I normally wait until it is almost too late to change them. It is now fall and it is the first time in ten years that I have not had to change the rear brake cable and housing due to the sweat corroding and seizing the two together. The brake cable housings are nearly solid now due to the sweat but the cables are still working smoothly. For that reason alone I will install them again.

    The improvement in braking and shifting performance really is quite noticeable. Definitely an upgrade that works. Make sure you use some good quality housing cutters, a quality product like this shouldn’t be hacked with cheap cutters.

    I agree with all of the positive praise for shifting and braking performance-and they look cool, too. However, after just 6 months, the brake cables have noticeable rust showing through the liner. I’ve seen rust like this before. What a bummer.

    Difficult to work with the brake cables on 7800 groupset. They don’t like being bend too much. The ferrules are larger than standard Dura-Ace. But..they are awesome on feel and performance is significantly improve.

    Killer braking power. Makes my DA levers feel like they are hydraulic. Shifting is very smooth too. The brake housing is stiff, but still easy to set up. Good purchase.

    I replaced my worn Dura-Ace cables with these and what a difference. The braking and shifting are both way improved. Absolutely no friction in the brake action.

    I read a lot of positive things about these cables before buying them. I have to say that they are even better than described. I ride SRAM Red and what a difference. The shifting is much quicker and smoother. The feel at the lever is so much lighter that it feels like a different groupo. If you have SRAM, BUY THIS. You won’t be sorry.
