Anyone put an HC97 in a late model Lyrik?

I'm glad you're getting closer to a setup that works!

Are you sure you've got a C1 airspring in there? Those numbers are around what I'd expect for the B1 airshaft, but as you said, If it works it work.

Also important to check the pressure with the fork fully extended. Compress the fork a little and then lift it off the ground so that you have a reliable baseline.

LSR: -3 also doesn't sound too far out based on the Rockshox and other's recommendations. It may be worth considering stiffening the HSR shim stack if you'd like to open the LSR back up. The Push recommended tunes only require adding a couple shims in, if you'd like to dig yourself into a deeper rabbit hole.

The Norco Ride Aligned setup guide can also be helpful for getting your fork setup in the right ball park, 2020 Sight for 160mm B1 setup, 2021 for 160mm C1 setup. (although your numbers line up with the B1 setup)

Yeah I knownseems like B1 pressures but it's a C1 for sure (big red cup near the top) same as the 170 that was in there before. 

I need less than  recommended pressure with the 170, so it's wierd for sure. But it's getting better. Didn't get to ride anything real gnarly but I rode it at 114psi last night  (just what the resulting pressure was when I connected the new digital pump). Added 2 clicks of HSC mainly to make the LSC do something and about 5 clicks of LSC and seems promising.  

I may try a third spacer, or I may try 120 with no spacers. I am on track now I was just way down on air I think.

One other idea:

Experiment with bar height. When I went to a shorter travel 29er with longish reach and longish chainstays, but steeper head angle compared to my Madonna with a 180mm fork, I had the feeling that my fork dived and the front end felt strange. I fiddled with spacers and even fork travel and compression setup etc. and a firmer fork worked better in this respect, but I find it beneficient to use more of the travel on my shorter travel rig regularly, compared to my Madonna ( I don‘t do stunts which require 180mm on every ride). I do ride stuff which kind of warrants 130/140mm on basically every ride (that‘s in relation to what my body can take long-term, not what a pro could do with my bikes…)

But what actually solved this divey, strange feeling for me, even though I didn‘t expect it at all, was a higher riser bar and a more linear fork setup with enough suppleness.

My stem is set up with plenty (3cm) of spacers underneath (Orbea Occam, size Large, short head tube) and a +35mm riser bar.

When I look at the bike I would absolutely guess that the bars are too high. Especially in comparison to my previous bikes. (But kind of in line with what works on my Madonna)

Actually +1cm of bar rise changed the bike for me from „I kind of regret buying it“ to „I am incredibly excited to ride it and can‘t pick between the Madonna (which I love) and the shorter travel bike“. I tended to run very firm forks and low bars. Which made me never use all the travel, but worked. But it is kind of pointless to lug all that travel around. (But some security margin is nice…)

I could try it. The bars are currently 1100mm from the floor to the center of the bar end, which is not low by anyone's standards, but I could try more. My HD5 sits at 1110mm but has more travel so sagged heights are probably similar. 

I do love raaws tall stack heights. 

Going for a Dales/forever after ride today. Will be right in this bike's wheelhouse. And while not the gnarliest there's a few spots where if you have a poor fork setup, they'll let you know. Haha.

I have a b1 airspring you could try if you want. I like the c1 better personally. I like the higher ride and support I feel it gives. 

If you ran the same air pressure and tokens as the longer travel, what you did could definitely help.

What travel is your b1? 

So another 10mm of bars height with a 10mm longer stem to help keep the weight balance where I want, and 105psi with two volume spacers is... way better, but small bump could still be better, part of it is probably just the air spring itself. B1 160mm or 170mm springs seem real tough to get though. 

I may actually try 3 spacers and 100 psi.

There really isn't a length. You just pull the red bits off the shaft and put them on your old shaft.

A right true that. I have 160 and 170 springs so as long as I have a seal head and foot nut it's good to go. 

It's pretty close as is though, so I will keep fiddling for now..

Sorry for the running monologue but maybe it'll help someone in the future. 

Since 105 was better I tried 100 for fun. 

Terrible. I think the fork sags more and basically and just rides on the ramp up of the two volume spacers. Lower ride height AND harsher. Beat that eh? Lol. 

Next stop 110 no spacers.
