Re: [ST] Front fork bottoming with RT Valves.



There is no bump stop for bottoming on the ST/RS forks. They rely on the spring and the oil to keep from bottoming. If the spring and the hydraulics are overwhelmed, the fork tube hits the bottom of the fork leg and will clunk.

A single bump, no matter how big, shouldn't force the fork to bottom, the oil in the fork has to go through those small holes in the damper rod (and the RT emulator if installed - though a weak spring COULD allow the emulator to become unseated, minimizing its effect) and physics - you can only get so much fluid through a given size of hole - dictates that rate. A series of fast bumps that do not allow the fork time to recover could bottom the fork.

Perhaps the clunk was the RT emulator reseating? Sounds can travel strangely, there might have been something else that clunked on your bike too?

Agreed. But still noone as answered my question about the bump stop, hydraulic
or mechanical?
