Whats the Hissing about

northturton

I'm new to MTBing with a hardtail, I have a new Rockhopper Pro with RockShox Reba SL forks - yesterday I was riding along a lane, went over a cattle grid, and I immediately brought the bike to a halt after the grid because I thought I heard a 2-3 second hissing sound from the front end of the bike - first thoughts were a puncture - nope, nothing wrong. I still had a working front suspension - I don't think its changed, but as a newbie how am I to know?

Any advice? Do front susp forks sometimes behave like this?

Its the oil going through the fork valves - perfectly normal. May only do it on bigger hits.

try pushing own on the bars while holding the front brake and then letting go...
the forks should say summink like pfssshhhhfup

Totaly normal.
