Knolly recommended me an offset bushing, just 1 I believe that they kindly have already installed into the shock, and a headangle headset as well as running a bit more sag in other to bring the Geo back in place. I have a 1.5 degree angle set that was an absolute nightmare to put in.... Never again and I'll be getting a softer spring one day to set it at the correct sag. I'm using suntour durolux forks that have the same axle to crown height as a boxxer and marzocchi 380 forks as well. The bike feels great, slacker than 65 degrees. Sitting somewhere around 64 or so

I just submitted an order request to Proshox for a set of titanium offset bushings. I will post the cost with shipping once I hear back.

May I ask why you went with proshox vs offsetbushings.com?

Placed an order for a single offset bushing.
Will install with normal length shock to see how it feels.
Still on the fence about the long shock.

Still waiting on bushings to arrive but even with the shorter shock I was really happy with the ride.

Here she is all ready to go. Can't wait to get to the mountains.

What exactly do I need to run a longer shock on the Delirium aside from the shock itself?

You can over-shock with a 222mm (8.75") but you would need an offset bushing at the top of the shock.

This. We supply them direct to Knolly in fact! If you're just after one bushing, just make a note of your frame and shock models when ordering this - https://www.offsetbushings.com/products/offset-bushing

If you're after a pair, then this is what you want - https://www.offsetbushings.com/products/offset-bushings-pair

Just gonna revive this thread for a bit. I'm thinking about building up a Delirium with 26" wheels, 8.75 shock and 200mm Dorado. Anybody tried this set up before? Looks like with 27.5 wheels an offset bushing is required to correct the geometry but I'd imagine with 26" wheels and 200mm fork that wouldn't be needed since the BB would be lower and head angle slacker anyway. What say you?

I tried this, didn't love the results. Handling got quicker than I'd like compared to some other options.

I've tried the following DH setups, all using an X-Fusion RV1 which can have the same axle-to-crown as a 180mm single crown when set to 180mm, as well as an 8.75x2.75 shock with 2mm offset bushing.

200mm front, 27.5 wheels: bb feels high
200mm front, 26 wheels: solves bb issue, but feels a little twitchy in comparison to some other setups
200mm front w/ -1.5deg headset, 27.5 wheels: bb still feels a little high, much more comfortable in steeps with the angleset
200mm front w/-1.5deg, 27.5 front, 26 rear: back end feels too short when cornering
180mm front w/-1.5deg, 27.5 wheels: I found this to be the best cornering setup when using the 8.75" shock. I still wouldn't mind a slightly lower BB and longer chainstay, but it's by far the best of everything I tested above.

Thanks for that! I mean the whole point of 26" wheels is to speed up the handling so I'd be ok with that result. My main concern is the BB height while maintaining about a 64 degree head angle. Did you try the 8.75 shock without the offset bushing at all?

No, I didn't try it without the bushing.
