Rattling of the holder lock

Modified on Fri, 14 Feb at 2:37 PM


On some bikes in specific RPMs the lock of the CI Pad holder may rattle. The solution is not to tighten the nut.


The solution is to get a spring washer of this or equivalent specification: DIN 137A M8/8,4


Assemble the lock following the photo below. A thread lock is necessary to secure the nut.


Make sure to use galvanized spring steel, not stainless steel. Stainless steel has no modulus.
