A high-octane cable system optimized for today's brake and drivetrain systems. Featuring RapidWire Compressionless Technology & Jet Lube Housing.
Top Features of the Yokozuna Reaction Cable System
- Boost braking of road brakes, cantilevers, linear-pulls and mechanical disc brakes
- Jet-Lubed for smooth cable action
- Includes Jet-Lubed Shifter Housing
Truly compressionless brake housing used to be considered impossible to achieve. The special RapidWire housing delivers excellent compressionless performance for enhanced cable response. The Jet Lube Process injects the proper amount of grease end to end of the cable housing. This results in about 10% less cable drag.
A complete kit includes: housing and cables for both brake and shifting systems.
About Brake Cables
Brake cables can make a big difference to the way your brakes feel, a good quality set of brake cables should make your brakes respond more positively and be more controllable, this will enable you to manage your speed through technical sections while off road or descending on the road. The invention of the brake cable, known as a Bowden cable, has been popularly attributed to Sir Frank Bowden, founder and owner of the Raleigh Bicycle company who, circa 1902, was reputed to have started replacing the rigid rods used for bicycle brakes with a flexible wound cable. The basic design has remained un-changed, but improvements in materials and technology have improved providing a smoother and more positive lever feel.

Magazine reviews for Yokozuna Reaction Cable System
Review from VeloNews
Late in the riding season, the best ways to dress up your bike and make it feel like new include new cables and housing, new bar tape or grips, a new chain, and new tires. If you can't afford new wheels or other components, there are little things that can make a big difference.
It's especially true for shifter and brake cables and housing. Aside from just improving the feel at the levers, actual shifting and braking performance will improve as well.
At $60, a Yokozuna Reaction cable and housing set is probably not the cheapest you can find. But it's among the best, and without a doubt will improve both the feel and performance of your shifters and brakes.
Yokozuna Reaction cable setAmerican riders are not likely to have heard of the Yokozuna brand, but the Japanese company has been around for decades. For years as a subcontractor, Yokozuna has been providing cable and housing for high-end component groups to some of the top drivetrain builders in the industry. In 2005, the company entered the consumer market and is currently distributed in the US, Canada, Australia, and Britain.
A Yokozuna Reaction cable kit includes brake and shifter cables, and housing for both. Versions are available with mountain bike brake cables, and shifter cable for either Shimano/SRAM or Campagnolo. Ferrules, cable end caps, and 2 short sections of extra-flexible brake housing (for extra-tight handlebar bends) are included.
Holding the package, it feels a little heavy, and I thought it might be due to the very beefy-looking 5mm brake housing, which is about the most highly engineered I've seen yet. But I weighed 36-inch lengths of Shimano and Yokozuna brake housing, and the weight was equal (about 53 grams).
With a clear outer sheath, the brake housing has a distinctive look. The brake housing is composed of coaxial wire strands (just like shifter housing) over which a steel ribbon is wound, to keep it from splitting under compression. The whole thing is coated in a clear plastic sheathing. The see-through nature of it is cool-you can see the co-ax strands underneath the outer wind of ribbon. It's lined internally with a slick housing, which is "Jet-Lubed" end to end with light cable grease. The whole package makes for very stiff housing that is very hard to bend.
The 4mm shifter housing looks a lot more like standard coaxial SIS housing. Like the brake housing, the plastic sheath is clear, and it's lined internally and pre-lubed.
Also like the brake housing, the 1.2mm shifter cables are almost immediately notable for a unique look and feel. The individual stainless steel wire strands are wound more tightly than on most shifter cables I';ve seen, which makes the Yokozuna cables very flexible and supple. They are also quite smooth.
Ditto with the 1.6mm brake cables-they are wound tightly (but not as noticeably so as the shifter cables), are very flexible and very smooth.
Installation is the same as with any cable set. However, the brake housing is very, very stiff, so routing it through tight bends will be tricky. I was barely able to get it to bend to follow the groove on my road bars, but that was the only issue I had. (I preferred to use the normal housing rather than the short, flexible sections provided).
The amount of shifter housing supplied with the kit was barely enough to fit from the Dura Ace 7800 levers I have, on 44cm bars with a 100mm stem, to the downtube cable stops on my Trek Madone. Be careful with your install to make sure you will have enough shifter housing for your application.
Yokozuna brake housing is very stiff, but gives great performance. Good cable cutters are absolutely necessary, because both cables and housing are made of stout material. In fact, cutting the brake housing requires a bit of post-cut care, as the outer steel ribbon tends to pull away from the coaxial strands when cut. I had to re-cut the ribbon and bend it away from the cable path. Then, using a machinist's pick or other sharp tool to open up any crimping of the inner lining is helpful. Once ferrules are in place, everything looks and behaves as normal. The plastic shifter ferrules are not sealed (in contrast to Shimano SP-41 ferrules, which use little rubber o-rings).
Correctly installed, both braking and shifting feel fantastically positive. I would venture to say that the brake cable and housing combination is the smoothest, most solid I have ever used. Squeezing the brake levers, the cable pull is consistent and easy, and when the pads hit the rim, zero flex or sponginess is felt. It's remarkable how positive and uniform both the front and rear brakes feel.
Action at the shift lever was very smooth and consistent, more or less on par with my previous best experiences of cable and housing combinati
The Scoop: A premium brake and shifter cable and housing set
Pros: Amazingly positive braking feel, smooth and crisp shifting
Cons: Brake housing is so stiff it will not navigate sharp bends in routing

I notice there are 3 versions of this kit, whats the difference between the "MTB" and the "SRAM/Shimano" kits, i have a MTB with shimano kit so whats is the correct kit to go for?
The gear and brake cable outers are different in the Yokazuna cable set. The gear cables have longitudinal fibres to prevent compression when you shift making them very quick and crisp with shifts. The brakes a have a spiral metal band running through them. You will see the difference when you open the pack. You'll want a proper cable cutter to cut the outers properly.
