I rode the fork as provided to me for the test up until the air piston seal failure. When replacing the air piston I did not pull apart the lower leg on the damper side. On the air spring side it appeared to have 10-20cc's of heavy oil that drained out (looked like 90wt or so). Apparently it's the mixture of lubricating oil and grease? Maybe the SR Suntour guys can chime in about this?

When I replaced the air piston I used 20cc of 10wt fork oil in the lower leg as splash lubrication. They recommend 0wt30 or 0wt20 full synthetic motor oil that I did not have at the time. Better performance could be had with the thinner oil bath potentially. I also used roughly 10cc of Fox Float fluid on top of the air piston as they recommended a heavy gear oil similar weight to Fox Float Fluid.

I'm excited about the future improvements (especially to the air spring and damper) as these tweaks could really help the fork perform to its best. I guess we'll have to wait and see...

The claimed frame weight of the SB66 Comp (full aluminum) and SB75 (full aluminum) are both 7.75lbs.

The bottom bracket I used was the Race Face Cinch BSA30 which can be seen here: http://raceface.com/components/bottom-brackets/cinch-bb/cinch-bsa30/

Thanks Noah!

To answer your questions about the adjustments here is a more detailed summary of my thoughts...

Rebound: The adjustment range is very effective and broad from super slow settings all the way to springy fast with everything in between over its 12 click range. I was happy with my settings and never found myself to be "in-between clicks". The stock rebound adjustment range is tuned well.

Low-speed compression: The adjustment range is very good from almost zero influence (very active) all the way to firm, but not super firm support at the extreme of its 9 click range. I would like to see an even firmer fully closed setting for more low to mid-speed compression support. This adjuster will most likely work fine for most people, but I feel it could be better with even firmer stock settings especially the transition from low to mid-speed compression.

High-speed compression: The adjusters range is very broad and, but goes from a stiff setting at fully open to an extremely stiff setting at fully closed over its 12-click range. I felt that this adjuster didn't have a very usable range because as soon as you start to get past 2-3 clicks in (from fully open) things start to get harsh over choppy/fast terrain. This is where I felt there could be the most improvement to the fork's performance by re-tuning the high speed circuit to have a more forgiving and usable adjustment range.

Does this answer your questions?

It's awesome that you noticed that as my final settings were 2-3 clicks in on high-speed compression and fully closed on low-speed compression.

It seems like all that really needs to be done to the damper is a re-tune of the compression shimstack setup with potentially a different springrate installed for the high-speed compression adjuster.

With Eric Carter now working with them on product development I'm betting he'll have some good ideas for them to get their base tuning more spot on out of the box. I can't wait to see where he takes them!

I feel like it's the other way around...yes DH at the elite level is serious, it's always been, but it's also a hell of a lot of fun! Enduro has become too serious in my books. Riders showing up weeks in advance to practice, people cutting courses anywhere and everywhere they can, people training like elite XC racers, crazy tactics etc...Not really my cup o' tea like I thought it would be...Long live DH!
