New Ohlins front end review

[Shaun]

Stand corrected sir! Left leg compression, right leg rebound and yes indeed big benefits especially in damping response time.
Yes it is fun! And I concur, thanks JD.

Hey, I was standing when i said that!

Keeping the R and the R together may save some confusement perhaps

[cowpoos]

ummm...yeah on the cavitation issuse...why hasn't someone though of having a separate air canister away from the forks...so more oil can be used in the forks...reducing the risk of cavitation?? cheaper that pressured gas!

another question...has anyone tried modern MX forks [obviously rebuilt ones] on a road race bike? larger rod,piston in the cartridge would displace fluid faster?? stiffer,etc??

Q1


Cavitation is caused by the change over point from compression to rebound, ie, the system is not ready to be going up or down, it is like US, confused!

That is why the left and right leg need to be seperated into there own depts, so the reaction/action is more instant/controlled

just like on the ohlins ttx realy, Twin Tube!



I think?

But I am just an old rider, CKT and JD will awnser this fully I am sure

[cowpoos]

oh...I thought cavitation is the mixing of air and oil...which causes the oil to loose its compressive qualities...and making damping less predictive.

[Tony.OK]

Ahhh me too......................so by having the comp/reb in different legs, does that introduce any negative forces such as the forks trying to twist in the triples because they are doing different things?
Or does each leg cancel the other by being neutral when one fork is doing its specific damping?


This threads turned into a goodie

[cowpoos]

I would expect the forks to work as one unit once bolted together...but there are alsorts of twisting forces at play...so I'm probally wrong??

[FROSTY:Me]

hey guys maybee I'm wrong but I think theres a strong argument for suspension with limited adjustability for road riders.
Sorta set it (*to suit the riders weight and style) and forget it.

Stop standing on your head, my typing fingers are arthritic........

Yes I hear what you are saying. Having more adjustments means you can also make it really bad!

Axle clamping area is largely ''ample''

Stand corrected sir! Left leg compression, right leg rebound .

Wasn't that what Marzocchi did with the M1R forks?

[Shaun Harris]

oh...I thought cavitation is the mixing of air and oil...which causes the oil to loose its compressive qualities...and making damping less predictive.

Tech YES, BUT what has caused this, is the fact that comression stroke and rebound stroke cross over in the OIL/gas circuit, hense becoming confused, and not knowing what to do.

RE your post about an air circuit, I do not think an air circuit would be a good move, imaging the H20 being introduced into the oil circut? if things are bad now, try riding on Air bubbles

it would be

you got mE, you got me not, you got me, you got me not bla bla bla crash

lUCKILY I am only a test rider now eh, and NOT the technician doing all the internal mods

Cavitation is only one aspect that has to be taken account of in the whole system, the few that I've seen that have cavitated have been poorly thought out aftermarket systems, by building a system that builds cartridge pressure rapidly it can be avoided.

Cavitation can occur during the compression or rebound strokes whether one leg is rebound or one compression it's all about pressure management within the cartridge, the only way to eliminate it completely is to pressurise the cartridge.

its been done a bit actually...WP,sqoi have sets like this.

So Gas forks with one rb and one comp, would be the best way to go? If one leg is trying to do 2 jobs, the chance of cavitation must be higher, than a fork only doing one thing at a time?
