I’ve been running a 220 rotor on my 36 with a Magura +40mm adapter. Works great and I really like the extra power.

If I were interested in running a coil, what spring rate would work best? I'm about 175lbs kitted up ready to ride

Try a few spring rate calculators:

Looks like around 400lb according to the TF tuned site. Thanks for those

I don’t know if it’s specific to the spring / shock combination I’m using but on my 2022 sentinel alloy I’m running a 500lb spring - the tf tuned calculator suggested 393lbs for me. I’m 167lbs at the moment - not kitted up. So probably a similar weight to you.

I tried a 400 and a 450lb spring and both bottomed too much. I then tried a 450-500 progressive one which was better - but the 500lb one seems perfect so far.

That said I know someone who had an EXT shock and spring and they were using a softer spring fine - maybe the HBO on that shock meant less harsh bottoming and perhaps it had a better lsc / lsc tube than my Kitsuma coil.

Joe Bristol. I think you meant HSC Tune not LSC Tube? Low speed oil velocity damping should not affect spring rate. High Speed will affect how easy it is to bottom out as it is high speed events that result in full use of suspension stroke.

I used to own a Ripmo AF, now riding a carbon Sentinel V2. Sentinel is a lot more fun at the bike park and the Ripmo is more fun seeing what you can climb.

Second this. I’m on an alloy with the CC link running a 500 at 162lb body weight. I’m going to try a 475 here soon just for tinkering purposes.

Some of this will be an inevitability. There should also be a Smuggler replacement coming too, the Spur ain't it

Looking for a “super” Spire next,190mm/190mm…. Pole just came out with a new monster enduro bike….. they also are running “zero” drop bb that they claim make extra slack bikes work better. Just a thought

Saw some spy shots of the new smuggler on a FB page, hopefully coming sooner rather than later

What trunnion shocks tend to have issues on the Sentinel? Have a DVO Topaz T2 currently and pretty sure it can't handle the loads as the stanchion has rub marks on it. Are coils ok? Shaft sizes are typically bigger on coil shocks but they don't have a big stanchion over the top of it. I verified my frame is aligned properly so that isn't the issue.
