Disclaimer, I only have a very limited understanding of suspension kinematics, but if basic math still applies here, and I am not overlooking something obvious, this should hopefully be correct. Let's also call the 230x65mm shock (with offset bushings of either 2x2mm, or 2x3mm) a
225x65mm from now on, for the sake of simplicity.
Not a bad suggestion. My main concern would be how much it would alter suspension kinematics.
You're welcome! I mean, if you do the math again:
Your geometry, after the same sag, is almost unchanged when running the above shock configuration. Now let's assume you run the bike as a more DH-geared kind of bike, with more sag (than a 160mm Enduro.
This would mean your (admittedly not static) sag point is either at [210-(55*0.28)=
194,6mm] or [225-(65*0.35)=
202,25mm), this is not a lot difference in the mid-stroke.
Again, I could not judge how this might affect smaller and mid size bump suspension behaviour, anti-squat or such things. But I am sure many of you guys could interpret the curves in regards to that.
The mullet configuration is meant to run 27.5x2.8 and not the 2.5 I'm running. The bike is currently in the highest BB setting and still has a pretty low bb.
Then my example calculation works out even more in your favour, I guess. If you want a higher BB anyway, there is one less thing to worry about, when attempting such a conversion.
I'd love have some clarity from hybridizer on how much shock I could run and how much it'd throw off the kinematics. There's enough room out back to make a new link for a longer shock. I've reached out to them but not heard back. They probably think I'm crazy.
I'd like to buy a size large for myself and run 190-200mm boxxer up front with as much travel as I could squeeze out of the rear.
I doubt they would give you any concrete numbers. You should be able to do that math yourself with linkage software, maybe someone in the forums will be kind enough, to measure the points for the suspension for you. Or maybe Hybridizer will actually provide you with that data.
I am surprised you didn't get a reply, or that you are that crazy - there may or may not have been a guy asking for wider/modified rear triangle (for 197mm hubs) just very recently. ^^
I doubt they would fabricate another linkage, for the same reason they will not do a fat bike rear-triangle, the need to redo a lot of the engineering effort, while likely not being able to sell many of those units.
In your case it presumably very easy to modify the frame, you just put in another shock. In my case, the effort is at least a magnitude above that.
Regarding rear travel, with my above example you'd end up with 189mm of rear suspension. That doesn't seem to shabby, doesn't it?
