Stumpjumper Evo suspension has me stumped-where to go from Fox

I also just took out the spacers from my 36 grip 2, cranked up the air pressure, and its made the fork perform way better. I still dont feel like I have the float x where I want it.

Maybe I’ll try the 36 with no spacers just to try it - I’ve only tried 2, 3, or 4 spacers.

Stumpy Evo are already high leverage. I don't think a link with more leverage is a good path for shock welfare reasons.

FLOAT X and Super Deluxe tunes can be anywhere. The Fox GRIP damper is better than the Select+ damper but both choke on sharp bumps. The Zeb is very progressive in the air-spring and pretty heavy for a 150mm bike.

Bolt on improvements that fit your requirements are the Mara Pro and Mattoc Pro/Comp/Expert. The Fox suspension can be modified and tuned to solve the issues as well but cost is probably the same or more than selling your current suspension and upgrading.

Yes higher leverage, but not very progressive at 19%. A pretty flat curve. With the small volume spacer and very soft compression tune that the stock Float X comes with they bottom quite easily unless running 20-25% sag (which then makes them harsh).

I found that with the Cascade link, and a larger volume spacer, it was much more supple on small stuff without the pedals dragging in the dirt and had more bottom out support. The link bumps progression to 26%, which is much better.

It was $ well spent. What's $250 for a frame part when a set of tires alone can cost $200?

Probably a really good idea. 2, 3, and 4 spacers is a lot.

I found the fox 36 and older fox 40 needs no spacers to feel good, where the fox 38 needs one and have a bit less PSI to feel right.

Maybe you’ll find a sweet spot. After owning three StEvos, I never could. With Cascade, without, air, coil … The bike feels nice at first, but as speed increases you’ll find that rear-end skitter you’re describing.

The Sentinel, in my experience, isn’t any better in that regard. It looks and pedals better, but the suspension just doesn’t eat high-speed chunk like you’d think it should.

In that particular area, the Druid (or any modern Banshee frame) absolutely slays.

Im really interested in trying a Banshee but no opportunity to demo in my area.

I’ve whined about this at great length elsewhere so I won’t belabor the point, but part of my problem is that I can’t demo ANYTHING where I live.

Hope so - the constant frame swap game is honesty getting frustrating. With any luck, there won’t be moves and employment changes next summer for us, and I’ll have a little bit more budget if I need to change bikes again.

Unstable at speed like that is often caused by insufficient compression damping. This is made worse by the Stumpjumper being very high leverage so shocks which normally have enough damping don't.

The Forbidden Druid is a very low leverage bike, so the same shock tune will feel totally different. Firmer at low speed but more composed going faster.

It's a shock tuning problem.

That would be high speed compression, yeah?

Yes, low speed compression also matters but high speed compression is the bigger problem.

I see. The SDU air I have is tuned for a Revel Rascal. In its current state, would that make the situation better or worse? The effects of leverage ratio is still a new concept for me.

Leverage ratio squares, so 10% difference means your damping and spring needs to be 20% different.

Stock RS tune or what in the shock?

There are some riders here that have more experience with more different bikes than I personally do.

However, I really enjoyed the rear suspension on that bike with a Cascade, Mara Pro & a mullet clevis link but still running 29" rear wheel. But I rode my old bike just last weekend (sold it to a friend) with all of the stock parts and it didn't feel very good.

If I was going to invest a bunch of money in a frame that will certainly be replaced/ updated very soon, I'd probably want to test the new Vivid Air and I'd consider the Cascade just a requirement.

Yeah, honestly if I can get it close as possible with the stuff on there now, that’s probably best, so we’ll see.
