I have a 2007 Fox Talas RL fork with a very strange issue. On trail performance is fine, however when I'm either on road or a smooth trail the problem that I'm experiencing rears is ugly head. The fork will gradually bottom out when riding on the road or a smooth trail like a rail trail, fire road etc.
It slowly sinks down from full height (even at 140mm) so much that there is only about an inch of slider tube visible out the top of the fork leg. If I bounce up and down on the fork it will pop back up, sometimes to full height sometimes only half extension. If stop the bike, get off the bars it will come back to full height.
As I mentioned when on normal trials with bumps, rocks, roots it generally performs as expected.
Rebound is set to the middle click or so and I've tried the PSI starting from 90 up to 140. I weigh around 230.
Does anyone out there have any idea what might be going here? It's driving me nuts!!
