Low Speed vs High Speed Compression

This is really for those who love to jump as much as they love to tech.

Does anyone run their LSC as hard as fuck but run their HSC as soft as fuck, give or take?

James mentioned something to me that clearly showed I have no fucking clue what I'm doing in regards to suspension setup and that I should come back with my bike to set it up properly. He casually mentioned I'm probably losing speed going into a jump, which if you saw any of my whining in the WBP threads, made me scream in anticipation.

Given that I'm really fucking impatient, is there someone here who can either give me a hint of what's to come or point me to a page or two that I should read?

I always thought I needed to go 'softer' in the rear to temper bucking but sounds like I was completely ass backwards on this.

(Yes, I'm going to try it out, but not for another day and you may be able to save me from a visit to the clinic. Think of my children.)

It's literally what the name says. Your shock shaft or fork stanchions move against the shock body or the fork lowers. If they are moving slow the low speed compression is in play, if they suddenly move really fast then high speed compression takes over. Adding damping in either situation will reduce oil flow to try and slow the suspension down.

I've always tried to balance my suspension front to rear as equal as possible and have a really neutral riding position unless im cornering, then I like to weight the front wheel a bit.

Low speed compression really doesn't do anything for bumps, adding low speed will help your suspension keep a stable ride height as you shift your weight, corner, brake, pedal, hit lips, and get G'd out.

High speed dampens the fast hard hits like rocks, and bumps.

If your spring rate and sag is set up correctly, yes. You could run lots of low speed as to not loose energy needlessly cycling your suspension on jumps and in corners. Running your high speed settings on low doesn't make your suspension really any softer, it allows the suspension to cycle the most efficiently. Adding high speed is like adding progressive friction to the suspension.

If you really want to see how far the rabbit hole goes, you need to read mtbr or ridemonkey.

Your settings are also hugely dependent on which shock and fork you have.

I run middle of the road on both settings with an older Fox shock and just below the middle on rebound. But I am also 220 without gear.

My understanding is that each brand seems to have a different lsc/hsc sweet spot.

Bucking is more about rebound imo, I have found slower rebound adds traction and increases speed and control……and reduces bucking.

Also, On most suspension low speed is the more prevalent adjustment. Manufactures tend to over dampen products too be safe. Running mid to high low speed compression will affect the high speed circuit on most products.

As rider weight increases, so do spring rates and velocities. All making the dampers job more difficult. For heavier riders running alot of damping you really tax the suspension. I used to get less than a day on the WBP running TPC+ Travis by smashing lube oil into the damper. Fox 40s lasted a couple days before I blew the bladder. Boxxers were noodles and good luck with the bushings. Ive had better luck with rear shocks since they are designed around high leverage ratios, but still managed to ruin them inside a month riding WBP.

Setting the rebound I usually start with the curb test. Run zero rebound damping, drop off a curb or ledge. Keep adding rebound damping until the bike only bounces up once to the sag position.. For me this ensures the bike is predictable over rough terrain and will help tame getting "bucked". Sometimes I like to reduce the rebound damping in the fork slightly if my hands get sore from braking bumps. Being able to adjust beginning and end stroke rebound seperately would be the shit for that.

Thanks guys. I get compression and rebound dampening on their own, I was just hoping I'd be at a point where I could look at the frame and say the three fork settings should be this and the four shock settings should be that.

Right now unless the manufacturer gives me a base tune for a specific shock and fork I'm pretty much Constanza'ing the settings.

DI: I never thought about rider weight and more compression damping affecting the shock/fork, but it makes total sense. I too am not wee in any sense of the imagination and suspect that adds to the challenge. I think I'm starting to understand leverage ratios a bit.

As for rebound damping, up until very recently I thought reducing rebound damping was the key to not getting bucked at the lip of a jump. Fuck me.

Yeah, me too big time. Tough to find three others to go at the same time though.

^ I'd possibly, maybe be a +1 to that
:fruit:

if you want baseline settings for your 40 for your weight
