Galfer Chrome Brake Rotors

Always Wave, always top quality, the newest on our family of rotors, Galfer's bling-bling performance version of Sport Bike wave rotors. Makes many front ends lighter than stock by almost 2 pounds, as the wave rotors average approx. 3.0 lbs per side. Made of High carbon content stainless steel, unique for providing a high level of friction, and a good heat dissipation.

Specifically design for high speed racing, performing very well on the road. Cad CAM laser cut, first the metal sheets pass a stress relieve process, and then they laser cut them, this makes the product perfectly flat. Self cleaning and cooling action as it rotates. Full floating. Sold in pairs, Made in USA. Can be sold individually upon request.

Galfer’s Wave Rotors are characterized by their excellent quality. All Galfer Wave rotors are laser cut and made of a unique high carbon 420 stainless steel material that has been pre-heat treated and parallel double disc grounded to assure perfect flatness and the most efficient contact surface between pad and rotor.

GALFER Brake Rotor FAQ's

Why go to a bigger diameter disc?
Bigger is better! Right?!?!? Not necessarily. A bigger diameter disc does  provide more power and better cooling (because any particular point on  the disc spends more time in the cool air dissipating heat buildup) you do end up with less modulation (brake control). Traditionally, downhillers,  free riders, and tandem riders can all benefit from larger diameter discs.  However, riders who spend more time in technical situations need to be  aware that the larger diameter disc (like a lower bottom bracket) has a better chance of being struck and damaged by a boulder, tree stump or  similar object. Take a look at motorcycles and the diameter of their brakes.  Most motorcycles run a larger (or dual) front brake rotor setup

Materials.
Galfer uses only 420 or 410 stainless steel for all of our brake rotors  and it’s all about the memory! What do we mean by that? Metals have memory which means that when you heat up a piece of metal and it expands,  good memory characteristics allow it to go back to its original shape  without much deformation from the original shape. It’s as simple as this: It goes back to it’s original shape and specs faster.

Laser cut vs. stamping.
Stamping is great when you are doing mass production of tens of thousands  of rotors. This is because the stamp itself is VERY expensive to make,  but after the initial expense, it can quickly produce rotors that are relatively good quality. On the other hand, laser cutting requires minimal initial expense other than a few hours programming time to make sure the  laser follows the desired pattern. This allows you to easily and cheaply  change the design after testing if the need arises.

Because the programming time is all that is required for a completely new prototype, Galfer has the ability to do small batches of custom rotors to meet the needs of our clients. Galfer can do an infinite number of combinations of diameter, bolt fixing pattern and wave pattern. We can even cut your company logo  or name into a rotor design. Laser cutting provides the most consistent  cut quality and leaves the rotor substantially flatter than stamping.

Why the Wave pattern?
Admit it! You’re interested in Galfer waves because they look cool!  We like the way they look as well but believe it or not, there is quite  a bit of thought that went into our patented technology. On a normal round  rotor, the leading edge (think toe-in) of the brake pad is in contact  with the entire height of the blade as the pressure is applied. Because the contact covers the entire height of the blade heat buildup takes much  less time to occur and you end up with heat related problems like brake fade, thermal lockup, and inconsistent braking performance.

What the wave pattern does is take that leading edge of contact between the blade and  pad and constantly move it up and down, thus minimizing heat build up  and its inherent problems. Cool air is also introduced in greater amounts.  In addition, through centrifugal force, any foreign matter is thrown clear  of the outer rim of the blade and doesn't’t get lodged in the pad  material.

Do holes in discs help?
Well, it depends what you mean by “help”. Holes in the “blade” of a disc (the part that the brake pad sweeps over as it is in motion) will save a bit of weight but contrary to public opinion, they do not  help to cool a braking system. Notice on MotoGP motorcycles and most race cars, there are no holes on the rotors. There are actually situations  where holes can be detrimental to your braking.

In muddy conditions, dirt gets trapped in these holes and proceeds to chew up pads that, in turn will chew up rotors because of the constant uneven abrasion between the pads (which have the dirt imbedded in their surface) and the rotors, which  get gouged to heck by that dirt. If you’ll notice, if there are holes in a Galfer rotor, they are never round. They are usually oval, teardrop or cylindrical in shape so that foreign debris is directed away from the rotor via centrifugal force.

Who does the testing on Galfer products?
We do! At Galfer we like to joke that we are world-class riders, but we  know what the truth is! We’re slow compared to some of our sponsored  athletes. That’s why we sponsor some of the finest riders on earth  before releasing our brake products to the general public. Teams like  Maxxis Racing and Santana Tandems for our bicycle products, Yoshimura  Suzuki superbike team for our road motorcycle products, and AGP racing for motocross, and World Trials champion Dougie Lampkines thrash our stuff on a regular basis. And we feel that if those guys love our stuff, then  you will too!

Do you make an oversized motocross rotor?
It depends on what you mean by “oversized”. There are a couple of companies who do a 270mm rotor kit that requires a bracket to reposition the caliper. This was a great kit 5 years ago when stock front MX rotors were 240mm and the jump to 270mm gave a definite increase in power. Today,  the OEM’s stock sized rotors are 260mm (only a 5mm difference in  rotor radius) and the power difference is almost nonexistent. When you  factor in the extra cost of needing a caliper bracket, it doesn't make any sense to go to one of these particular oversized kits. But we do make  a 320mm kit for most modern motocross bikes that are to be raced on the supermotard circuit. We also carry Brembo master cylinders, brackets,  and calipers for Supermotard applications.

Why do your front sportbike line kits not follow the stock routing?
Almost all of our front line kits are 2 line systems that have both lines  exiting from the master cylinder and then going down to their respective  calipers. We have found that this type of routing allows for shorter lines, which allows for a firmer brake feel.
