[Closed] Rear travel and not using it

Got a 2019 genius with 150mm on the back and 160 fork. I use 90 to 95% of fork travel in my normal peak/lakes riding. However on the rear I am only getting 75% so about 115mm out of the 150mm with 35% say. It does feel a bit harsh through the rough stuff and I can't decide if I should just run more sag or there us something up with it as Scott recommend 30%. For reference I am not the fastest out there but am generally top 5% on strava.had a patrol before and got through all the travel on that. Any thoughts

Drop pressure on the rear? Make sure it's fully unlocked.

Don’t increase the sag, that’s not likely to feel great at all (for many reasons). Can you lower the amount of compression damping? If not, a shock tune to lower it might be a good idea

do you know what volume spacer is in there? - if you have the largest - try the next one down.

Can't lower the progression band wise as none in it, it has the new progression switch which is exclusive to Scott i think, the equivalent to adding spacers. Could run more sag as it's the twinloc system so you can click the switch for pedalling but seems a lot at 35 % plus

Are you setting your sag sat down on the bike or in the attack position.

I often get commented that visually I run too much sag when sat climbing Bike rides fine when I get up on my feet /as arms and the propede/DW linkl handles the excess sag and rides great.....

When I did it sitting down it was Skippy on downhills hardly used travel as funny enough I don't ride down hills sat down

I do the sag sat down will try stood up and see, for some reason I always thought I would need more air if measured standing

I have the opposite problem, in fact my rear shock works so well that I've stopped mid trail before to check if my rear tyre was flat as I could feel no tree roots, rocks or braking bumps through the rear wheel!

Try setting sag standing, in the position you will descend in

When you stand you will move your weight forward, so more weight on the fork and less weight on the shock.

If the shock feels harsh, and you are not using enough travel it sounds like there is too much spring pressure or too much compression damping.

Go for a ride with a shock pump, let a bit of air out the shock and see if it rides quicker/better and uses more travel.
Have you got much compression damping wound on?

I'd go with the above about trying some pressure changes on a ride, there is a chance it's well set up and you are not needing to use the travel in that situation, means it's there when you really need it 🙂

From some chats with other people and stuff on here would a shockwiz be a good thing to try for a few rides?

Stood up sag method I am at 27% I will drop some out and take the pump with me next ride, there is no compression damping on

That makes no sense at all, if your rear tyre was flat you'd feel absolutely every trail imperfection / feature you rode across as your wheel rim would be smashing into them with no protection from an inflated tyre, it would also be noisy as hell. Have you considered a career in MTB journalism and reviews?!?!?!

If letting a bit of air out gives full travel but doesn't get rid of the harsh feeling, it might be you need fewer volume spacers in the shock?

You never had your tyre go down a bit so you can't really feel what the rear wheel's doing any more? I get what tallpaul means anyway, cane creek shocks can smother the trail feel a bit sometimes.

No volume spacers in it so hopefully air out will work

As above try adjusting the sag to 30% while standing and see what it feels like.

Also maybe try slowing the rebound down? Over choppy ground the bucking bronco effect that a fast rebound damping causes can often just feel like a harsh ride as its hard to deferentiate the bumps from the ground and the shock extending too quick?

You want to find a happy medium, go too slow and the shock will pack down over successive hits.

How much do you weight? If you are on the lighter end of the scale towards 60kg possibly you are outside the optimum band for the damping.

Might be worth experimenting just how much sag you have to run to get the shock to feel supple and feed that back to the manufacture to see what they say. Could be a faulty shock?

I am 95kg so more likely out the other side damping wise 😎

are you sure you don't have compression wound all the way on, rather than all the way off?

The compression adjustment is via Scott twinloc which has three trigger operated settings which you cannot get wrong, the only air volume adjustment is via i switch which I have set to linear

If you're only getting 115mm travel on a Genius, sounds like it is in traction mode and not in full travel mode. I'd go for a ride with Twinloc cable removed.

I have tried disconnecting the cable no difference

Are you charging the negative spring as you inflate the shock? Compressing the shock every so often as you pump it up.

Does the shock give full travel if you compress it with no air?

Yeah i had been trying to charge the negative every 50psi or so, it does get full travel with no air, hopefully the 10psi I have just dropped may help. Going to give it a go tomorrow
