… but I thought it is FM 160 => PM 160. Are you sure it is FM to PM 180?

Yes, it is FM160-PM160 on the rear.
And the rigid fork has a PM 160 to PM 180mm adapter

Don't think I saw your post, and well, you know what search function is like on this forum

I recently discovered the search is contextual to the post you look at.
For instance if you are on a 29er page, it won't search the road posts.
Not perfect but way better to find things, like my post about Ritchey's headset above.

...Otherwise a properly tuned modern shock should be ridden open...

Are you tuning your shock yourself ?

Thanks.  I'd never seen that mentioned before.

Sure ?

I recently stumbled onto the website www.sportpursuit.com  You have to sign up to view their site/prices. (its free) They sell closeouts on cycling and other outdoor gear.  Some crazy deals on there but size selection can be limited at times.

They have sometimes good deals, the return are paying but works well and they have a very good support in case of troubles.
It is a business model where they collect our money, and then buy the items from a bankrupt company or some end of stocks.

In most cases, you can always find items at the same price or even lower when looking for the same products on Google.

They have as well their own brands too, that are kind of so-so( Rivelo, RULE#XIV, Isoobaa, Fjern,...), on which they make you feel you get a big discount while they are the only one selling them.
They build a mostly empty web site for each brand, with nice looking people that look cool in nature. To give them some credential.

I may look negative, but not, I bought a lot of things from them knowing the above.
Recently Sportful jerseys at Aliexpress like prices, and some Rapha garments.

privatesportshop.com has the same business model, and they could be recently connected as they start to sell the same stuff.

It's aliveeee!

Nice bike with a nice view ! 
Do you have the link to the bar/stem combo ?

I was going to ask here if someone did try to install a non-boost Eagle crankset with a 34T Oval on the FM909.
To have a better chainline on the big cogs, like I did on my FM936.

But then I did some research.

And found an article from WolfTooth: https://www.wolftoothcomponents.com/pages/boost-chainline-and-chainrings
Telling that it is a quite bad idea on a 12sp 1x, as the chainring is 3mm more inward, and crosses more the chain on the 2-3 smaller cogs.
And it may touch the cog just above.

I instantly understood why my chains have this strange lateral wear.
So I wrote this other message to make you benefit from my smart trial...
