About

The Product

Crisp Brake is a new and a much better brake than everything that is on the market right now. It is stronger, lighter, easier to use, look after and install.

Crisp Brake MTB uses mineral oil which is known to be easier to use, bleed, and does not corrode your paintwork.

Crisp Brake MTB uses the post mount standard, and bolts straight on using your existing disk.

Crisp Brake is suitable for all disk sizes from 160mm and up.

Manufactured in Perth, Western Australia you are getting a slight cost increase but the quality of our product can be controlled throughout the entire process.

Set and forget reliability

What you get

1x Crisp Brake MTB calliper
2x Crisp Brake MTB specific sintered pads
1x Lever and 1500mm of hose
2x M6 mounting screws
1x Instructions
Mineral Oil filled ready to ride

How it works

The Crisp Brake concept is very simple.
Instead of pushing pads from each side of the disk with two separate slave cylinders, we use a single slave cylinder pushing two levers apart that pivot against each other and then squeeze the pads against the disk.

Problems with existing Designs

Brake fade, sticky pistons, brake fluid boil, scored pistons, uneven brake wear, leaking seals, these are all issues that you may have experienced and they reduce the overall safety of a fully functional braking system.

Benefits and how they effect you

Reduced Brake Fade.
Improved heat dissipation as the calliper is not enclosing the pads, also allowing dissipation fins to be incorporated onto the back of the pads which enhances the cooling effects.

Reliability and Durability.
There is no reason why Crisp Brake would not be as reliable/durable as the best on the market.

One Slave Cylinder.
Keeps things simpler, less seals, easier to bleed, even pad pressure on both sides

Isolate Hydraulic System.
The hydraulics do not need to be as tolerable of heat and dust, reducing cost on ceramic pistons, special seals and so forth.

Simpler Shaping.
Reducing manufacturing costs as all the shaping is simple and easier to machine/forge.

Maintenance.
Pads are held in by a simple split pin, as the pads are not surrounded by the calliper access is even easier.

Performance.
The pad size is not restricted by the size of the calliper and can be made a lot bigger if required.

Weight.
Our current early CAD model is under 110 grams

Full Floating Caliper, Self Aligning.
As a full floating system, installation is very easy (no alignment issues at all) and even with a very bent rotor it would not be the end of your ride.

Crisp Brake is a better brake and that makes it a safer brake.

Patent Pending

Crisp Brake is Patent pending, this means we have the full right to take advantage of this technology, we also have to option to licence this out to existing manufacturers. This technology is applicable to not just bikes but motorcycles, cars and trucks.

This is the first major improvement in disk brake technology in over 60 years in the cycling, motorcycling and automotive industries.

The Future

One of the most exciting aspects of this concept is the progress into electrical actuation. This means brakes that are fly by wire. The future.

Applicable for the automative industry

As the slave cylinder can be swung around the pivot point to different locations we can use the same technology in the automative industry as it can clear the wheel, we believe we can keep within 30mm from the outside of the disk.

Invention story from the Inventor, Allan Crisp

As a guy who is constantly looking at doing different and weird things I came up with this idea while i was day dreaming riding to work one morning. Wondering why the brakes on my bike are so compact and don't take advantage of all that space that is around them. What would I do if I was to design them myself?... Well I came up with Crisp Brake, I then got pretty excited, researched everything I could and found a similar design is used on trains (quite recently) and has also been used on cranes and other industrial purposes.
This got me even more exited as it proved my idea worked and there were no patents to use a similar concept in the cycling, motorcycle and automotive industries.
Now I went to the Patent Attorney and got the ball rolling with him whilst I worked on a prototype, I then quickly realised how tricky it was to get all the forces and loads the be strong enough to handle what was being asked.
I then contracted some help, Engineer Michael Reeves to help with the maths, simulations and designing the first production model.
Completing my first prototype calliper was a massive achievement, I was super stoked. I got it running perfectly the Friday afternoon before I headed down to Pemberton with some mates to compete in the WAGE MTB Enduro race round two. Racing my rigid single speed bike I was never aiming too high but I managed a 15th place in open mens putting the calliper through a massive workout.  I was thrilled it never let me down and worked flawlessly the entire weekend.
Now with the Patent Pending application filed, a awesome functioning prototype, CAD production model, and a Kickstarter Project launched.... I am in your hands :) Thank you.

Risks and challenges

Cost/Money, If we underestimate costs of local manufacturing in original run of product. We have quoted local machining and estimated costs for anodising, brake lines, pads and so forth giving us confidence but without the experience in this area we can only find out once it is done.
Paying for Engineering/Product Development (can be as high as the sky, based upon management). With 6 Years directing Crisp Engineering, Inventor Allan Crisp is very confident in his ability and depth of experiences to run this project without wasting time and money.
