Maybe it's just me, but I've never found the love for the late model revs. I have 2014's in both rct3 and rlt, and have gone back to older dual air. To get them soft enough to ride nice, they blow through their travel, but to stop them bottoming out, they feel harsh.One could almost say they feel like fox forks :behindsofa:
Ill try some tokens one day. Until then, preferring the older ones.
+2 for a bit less air in the front tyre though. 25 max for me, usually a bit less than that.
Not trying tokens? Maybe that's why you didn't have much success moorey? More tokens less external damping?
If you have tokens stick with a basic external adjustment setting and put them in, find one that's too soft and too hard, then tune with both of them till you find your happy spot, either too hard and less support or too soft with more support.
Keep tire pressure the same the entire time during testing.
Tune, write it down and ride.
OP, does the 2011 have tokens?
I had an issue with my 2011 boxxers where like moorey actually using the external adjustments made the fork harsh, yet it still blew though its travel too much, my ride felt very skittish at the front because of the high compressing I had to run. The reason? The shim stack.
Basically my understanding is that external HSC works as a threshold or preload for the shim stack so it doesn't actually stiffen up the entire stroke, what it does is just increase the pressure you need before it cracks open the shim stack, in my case to get the fork to sit up I had to run high compression making the fork very stiff and lack compliance on the smaller stuff, as soon as I hit something big enough though it would open the shim stack and blow through the travel. The solution is a shims tune. stiffening the shim stack and backing off the compression, this lets the threshold be lower allowing for compliance but with the support from the shim stack, keeping the fork compliant but supported.
In your case I would follow the advice of basic service and make sure to get the common issues out of the way, make sure they're not damaged or leaking or pressure lock anywhere etc.
If the fork is 100% functional but still having problems, id speak to rockshox and aftermarket tuners to see what they suggest.
I have no idea what your fork is like or the construction of it so I cant say what you should do.
Rebound could definitely be a cause, test that, but be careful you don't want to go OTB so adjust slowly don't just turn it to full slow.
One question though when you say you hit the bumps and it feels too stiff what travel is it getting? You might actually be running so little compression that the fork is running too deep into its travel making it feel harsher too.
Finally it could be body position, weight distribution.
First thing is to make sure the fork is functioning correct.
When setting sag make sure to bounce up and down a few time to release any friction is can throw off the setting.
Sag>rebound>compression.
good luck, sorry I can offer any real advice on the fork except for basic troubleshooting and contacting the pros.
