So nerdy! So good!!!!

[@smin4089]

I am loving the details

[@Allsystemsaredown]

Spherical bearings make great sense to me.

[@dince4716]

When talking about IFP Friction and Shaft Friction, would it make even less friction and Better durability to use an X-Ring instead of an O-Ring on the IFP and the Sealhead?

[@VorsprungSuspension]

@@dince4716 in theory yes, in practice we haven’t seen it work better, and quad rings are hard to come by in metric sizes as are required for the shaft. Further to that, the friction reductions with quad rings come from the reduced squeeze, but with reduced squeeze also comes less tolerance of eccentricity, which means side loading can more easily cause leakage, as well as lower wiping capability which means more oil residue on the shaft.

Good stuff. Did you decide on a new machine yet?

[@VorsprungSuspension]

@@timpaul1226 not yet!

I have a gen 3 levo. I have the cascade components link (160mm not the long travel version 210x55 I believe). Is the tellum compatible?

[@VorsprungSuspension]

How long is the yoke on that frame? As long as the total length (yoke + shock) is lower than 315mm you should be ok. For full details on why that is, check out this document - cdn.shopify.com/s/files/1/0767/8621/files/Shock-Frame_Interface_Design_Best_Practices_-_Rev_B.pdf?v=1724714800

What would be the different vs a push elevensix?

[@VorsprungSuspension]

The Elevensix is a solid shock. However, there is a $400USD price advantage to the Telum, Telum can be revalved in minutes at your home if you wish (see videos 3 & 4 from this Deep Dive), the Telum has polymer spherical bearings (no corrosion or play issues, plus lighter weight), and the Telum's warranty is transferrable down the track. The Telum's hydraulic bottom out is also adjustable (11.6 is not) and acts over a longer distance, which means it can be more effective and generate lower peak forces. Retuning the Telum for another frame is a sub-five-minute job if you ever want to do that too.

You should have gone with stainless steel. They have less friction and strong too.

[@VorsprungSuspension]

@@Trade2Invest- stainless steel damper shaft you mean? They have higher friction than hard chrome plating, lower hardness (more wear) and even very strong stainless alloys like 17-4PH are not as strong as the alloy we use.
