Hi, I'm EJ Dorrian, a home bike mechanic and a mechanical engineer. The intersection of the two created Crest Tool. I was disappointed with how far the brake lever on my mountain bike needed to be pulled to get full braking power. I couldn't find an easy solution to get the adjustability I was looking for, only various hacks that I found on forums. I had an idea that I thought might work, so I fired up my 3D printer and got to prototyping. After a few iterations, I developed the Brake Pad Advancement Tool that allowed me to get the adjustability I was looking for. If you have the same problems with your brakes, this tool is your solution! 

Each tool is 3D printed, assembled, and shipped from Salt Lake City, Utah.
