Why use the "Ceramic Piston" on caliper?

For the Piston, we upgrade it from aluminum to Ceramic in ELITE, SLP and USAGI models.

The "Ceramic Piston" is the best material that could reduce and insolate the heat, especially in the long downhill, it could help you to keep the braking power.

 

We test the "Ceramic Piston" including two popular brands, the Shimano XT, AVID Elixir CR brakes.
Test procedure:
1) 120N to pull the lever
2) 100kg loading, 12.5km/h speed, 3 seconds/per braking time, release 3 seconds, after 5 seconds braking again, do the same procedure 75 times, measure the caliper temperature
3) Using the same disc, 160mm rotor

You can see the temperature as below:
