With tires like these you will limit bike potential to a down-country territory at best. Around 850-900g per tire is kind of minimum reasonable, think of new Purgatory in T7 or T9 or EXO Forekaster as minimum from Maxxis. I used DHF MaxxGrip for all the colder part of the year, considering something little faster for warm period, but never an XC tire.
I would also reconsider simple SPD before you mount them for Shimano trail pedals for better support, it makes difference which is worth extra grams.

The 2023+ Deluxe and Super Deluxe shocks don't use the old Megneg air can. You now have the choice of a linear or a progressive air can and the Detrail uses the progressive one.
I now got myself a new Super Deluxe with the progressive air can and Hydraulic Bottom Out, mainly because I wanted the separate HSC and LSC adjustments also thinking about getting it custom tuned for the 1001. I'll write something about it when I got some rides on it.

Waiting for you feedback on this.
I saw small air can as aftermarket component, but never a Super Deluxe with small can out-of-the box. However, this is on of most promising shock without the need to modify it.

By luck, I seem to have hit it well then with the R232 shock from DT Swiss, which they say has a progressive curve.

But damper on R232 is probably too simple for this kind of bike, no?

As per my info, FM1001 has flat and quite "low" leverage curve. It needs air shock with a lot of progressivity (small positive chamber) and IMHO and above average low speed compression damping. Guys at Detrail are clearly aware -> they put small chamber & highly damped Ohlins TTX1 on their most expensive build. Also, for their "Berg" model they designed & created new rocker link and market its 30% progressivity (clearly a design objective to remedy problem of zero progressivity of the origianal).

And this interesting https://www.detrailbikes.com/berg-155/
Looks like they put different rocker (Alu instead of carbon?) to squeeze more travel and increase progressivity of our topic. This is exactly what I want, may be not up to 155. Interesting approach instead of using FM1002...

Some more review https://enduro-mtb.com/en/detrail-stig-135-test/

I agree with the negative points of the review, personally I increased fork to 150 and have tons for 3d printed spacers and custom shim stack to boost compression damping....  (both providing more "support" for the rear).

Two small changes that I have made.
I've removed my Zefal downtube armor today because it didn't really stick at the edges and started to leave black marks on the paint. Replaced it with a Nukeproof Mega Alloy Downtube protector I got from wiggle, fits really well, upper part of downtube got some clear frame protection installed.

Modelled and 3D printed a small flap for the main pivot gap between main and rear triangle. Had a small rock stuck in there and quite some mud on some rides that's now solved. If anyone wants to print that one as well I can provide the STL file.

Thanks a lot for tip, Nukeproof Mega Alloy downtube protector fits really really well. As par chainstay protector Nukeproof Mega fits very good as well, just small cut. Alloy version fits much less. This kit from Nukeproof is kind of must have for FM1001....

Can you please share link to the rear stay protector? Looks very profi... thanks.

Sure, specs:
Frame: FM1001 XL, RAL7015 glossy
Wheelset: BTLOS 29i, Bitex Hubs
Tires: Specialized Eliminator Grid T7 29x2.3 front , Ground Control Grid T7 29x2.35 rear
Fork: Fox 34 Factory 2020 140mm, 44mm offset
Shock: RockShox Deluxe Ultimate 185x55 with MegNeg
Brakes: Shimano BR-M7120 203f/180r
Cassette: SRAM XG-1295 10-50
Crankset: SRAM GX Alloy, 30 tooth chainring
Derailleur: SRAM GX AXS with rocker paddle shifter
Chain: SRAM X01
Stem: Spank Split 50mm
Handlebar: OneUp 20mm rise, cut to 780mm
Dropper: OneUp 210mm
Saddle: Ergon SM Pro

I have done another longer ride and I couldn't be happier with the bike. Added some frame protection to the top tube and the seat tube to protect the paint a bit and changed the chainring to a 30 tooth (not the fault of the bike I'm just not in shape

I have few first rides with DVO Topaz shock tuned by https://insanityofgravity.blogspot.com/2023/02/18-suspension-setup-ausfuhrliches.html
and subjectively if feels day & night compared to factory setup of the damper. 100% recommended for DVO/Suntour owners, new shimstack is described there, replicate spring update is may be not so easy.
It also confirmed thesis that FM1001 leverage ration is almost linear and needs a lot of progression to be added by the shock, so heads up for anyone running near-linear shocks. It makes shock selection for FM1001 little bit difficult / limited.

179cm and L feels little short on effective top tube, running 55mm stem and 10mm seat post offset to prolong effective top tube. Handling, reach & wheel base is nice for me with L. Cannot imagine down-sizing to M, can imagine going XL with short stem, but it would move trail bike into mini-enduro probably.

Can be FM1001 fitted with some angled head set? I am tempted to try -1 degree, specifically 64,5 HA with 140mm fork travel, 44mm offset. Did anybody tried?

Hello all, I'm very interested in this frame, but not sure what size would fit(M or L). I'm 175cm(5'9'') and have 82cm inseam. I find the STA of this frame is quite steep. That causes a relatively short top tube. I wonder if a medium will feel cramped or uncomfortable during some long and flat pedalling. But a large seems to be very long (it has 472mm reach and a 440mm seat tube length). My Current bike is a Giant Trance 2017 size M which has a 435mm reach, 73.5 degree of STA and 610mm top tube length. Should I go for a large? Or a medium of FM1002?

I have 178cm and L feels nice to little short despite 55mm stem and 10mm offset seat post.  With 44mm offset fork and 150mm travel the bike is surprisingly agile anywhere except uphill switchbacks. I don't dare longer stem in order not to cripple handling, which is very nice. I was and still tempted to try XL with short stem... But I cannot imagine myself on M. FM1001 has somewhat aggressive geo & long wheelbase even compared to contemporary trail bikes - if you are in, take L and short stem, if not, look elsewhere. Short offset fork probably helps agility and I don't feel any lack of stability at speed.

FM10 has 74 seat tube angle compared to 78 of FM1001. That is big difference and clear explanation of its longer effective top tube...
I actually like steep seat post more than I anticipated!

This frame's geometry is almost exactly the same as my FM10 except that the reach is about 0.5" shorter and the effective top tube length is 1.5" shorter. Also I had a 140mm travel fork on the FM10 vs 150mm on the FM1001. The FM10 felt like riding a chopper at times when I first got it. This bike feels completely different and seems to have a shorter turning radius. A few times going down drops the front wheel has gotten a little squirrely since my weight was so far forward on the fork. The steering is much more responsive all around and I'm still learning to use the improvement in control. Beyond that the change from X-Fusion to top tier Rockshox has been the biggest difference. The ability to lay down power over rocks and roots makes the ride much more relaxed and saves energy. I have more confidence in keeping traction through rough turns and the load on my arms and shoulders has decreased significantly.   
I added the RWC roller bearing to the top shock mount. The drag on the suspension was surely insignificant to the shock response but it just bugged me. :)
It's around 28.4 lbs with pedals.

Can anybody, please, measure head tube length of L-size including head set caps (if there any protruding)?

As per specification, it should be 120mm, but some millimeters extra and head-set cap/spacer can make my already cut fork unusable for this frame... Thanks a lot, Filip

Compression settings are dynamic property of the shock, nothing to do with sag.  You are asking for more linear characteristics, meaning playing with tokens in positive and negative chambers IMHO.

Can you please if possible report back change to tune to H M?

Thanks a lot!

I have the SidLuxe 42.5 in a M M tune and will send it in to be converted to a H M tune. It needs to be High compression and Medium damping.

I have to run it at 280psi to get 20% sag. This high of a psi prevents the shock from getting all 42.5mm of stroke.

Just upgraded wheels and fork. Switched to a 120mm fork and no more pedal strikes.
