New Bling!!

I decided to switch from the Avid BB 5 cable actuated disc brakes to Hayes HFX 9 XC hydraulic disc brakes. I also had 160mm rotors front and rear but I switched the front to a 185mm rotor for more stopping power.






The brakes come as a pre-bled system that can be installed and require no set up EXCEPT that both the cables were too long and needed to be cut down which is a process that I didn't want to tackle so I dropped the bike off at the bike shop. They had the cables cut down and the brakes bled the next afternoon.

The instructions said that the rotors require a burnishing period of 30-40 stops until they have full stopping power and when I tried them the first time I thought I totally wasted the money because they stopped worse than my old brakes. After more riding and stops they are now far superior to the old brakes. They also require a lot less pressure applied to the brake handle to have the same pressure applied to the pads at the caliper as my old brakes.





Pretty technical and boring explanation but at the same time cool.

Tomorrow will be the first time I use them in a race and I'm sure a post will follow as to how everything went.
