Have anyone here testet the "all hole closed" setting on the compsleeve?
I just built up a new 888 with lighter oil (5W) in the comp cartridge and "all holes closed".

Have not testet the bike yet, but the fork feels like it got much more low speed compression damping. Hopefully this will reduce diving, and give a more consitant feeling. The adjuster knob now works from 1/4 travel.

I hope it will open at higher speeds. If the fork spikes on hard hits, I will go with even lighter oil. Maybe drill out more holes under the comp valve in the bottom.

What do you think?

I have tested the all holes closed option. It was too much for me and did spike badly. I was using 7.5 wt. oil, so the 5 wt will help some, but I bet 2.5 will be needed to run the system with all holes closed.

Currently, I run with the top 2 holes open. It works great on the steep course of our Utah DH series, but has a small amount of compression spike on lower angle high speed courses.

If I had my choice I would like an adjuster that either covers the 2 holes on the left side of the damper or the 3 holes on the right side. I just might make one for testing this winter.

If you drill out more holes under the compression valve at the bottom of the damper, the damper tube may fail. The top of the damper tube supports the spring seat. I also doubt this will all for more oil to flow through the damper shims themselves.

I have been thinking about the durability issues about drilling in the cartridge myself.

2.5w oil is here ready to repalce if nessesary.
It might be possible to drill alternative holes it the sleeve.

I would love to see a cartridge with the possibility to change the shims in the comp valve.

How much do you weight BTW? I am 200 with gear. On firm and one standard spring and max preload on both.

I changed mine from 2 holes to 4 exposed, and it seemed to add a little more plushness back into the fork without the spikeing. Also using Golden Spectro 7.5wt.

Anyone have any idea why a compression adjuster would no longer have any "clicks" (detents where the rotation will stick). The knob turns to the stops at all the way out and all the way in, but when i went to adjust it yesterday it didn't have the little clicks like the rebound knob.

i know i ve been buggin ya alot lately, but ya can always trust a hope user ...since you re running the rissie crowns, can you tell me the total stack height of your ride .... headtube + headset (top and bottom cups) - basically the whole freakin deal... bottom of top crown to the top of the bottom crown... did that make sense ????????

any idea of the max. stack height on the 8" fork using risse crowns ??

cheers fella

Tighten the small crubscrew, and the clicks will come back

When I get home I'll measure it for you.

I tried this with 5-wt oil and it was still too harsh. Having all 4 holes covered makes the compression damping active throughout the entire stroke. So, even if one was to get the fork plush enough with lighter oil, they would just be defeating the purpose of the compression sleeve. That was with the 7inch version by the way.

Right now I got my fork set up with 5wt oil and the compression sleave in the middle of the 3 settings. So far this is the combo I like best. It's real supple on the smaller bumbs yet never bottoms on the big hits and doesn't dive in the turns.

I thought of drilling my own holes if I couldn't find a setting on the sleeve I liked. It seems you would be able to set the sleeve with all 4 holes covered and drill a series of new holes in the compression cartridge getting smaller as they go down and achieve a smoother transition to a higher compression damping and position it precisely where you want.

On the down side the chances of me getting it right the first time are slim, plus deburring would be a pain in asss, and now go ride brought up a new point about the structure.... If I could afford multiple compression cartridges I'd do it.

I dont think I am gonna drill holes directly in the cartridge. That was only a suggestion. I can drill holes in the comp sleve. Less than the middle setting, more than full closed.

Espen got me thinking about drilling the sleeve. And it seems that rather than make a whole new sleeve, couldn't you just set the existing sleeve to the position that covers all five holes and re-port it the way you like?

 

[Espen]

Exactly!

The only potential problem I can see would be making the holes too big. If that happened I dont think the fork would feel much different than stock. I would start with really small holes.


If you try it let us know how it works out.
