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
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
3) Using the same disc, 160mm rotor
