Re: FM1001 / FM1156 - 135mm frame
Kinematic analysis and "corrections" to the geometry chart.

Suggestion for shock
https://insanityofgravity.blogspot.com/2021/02/17-linkage-welch-art-von-luft-oder.html

Found these browsing the interweb so not my analysis. Not sure if this has been posted here already.
TLDR:
  • Pretty flat leverage curve.
  • Relatively low antisquat.
  • The blogger suggests Megneg shock
  • Geo chart isn't quite accurate.

Not sure if you can trust this one... He seems to use the diagram from the geo chart, which would be very unreliable.

I used the vector graphic sent to me from carbonda and got very different results, especially concerning anti squat and head angle.

Here's a screenshot. I put in a 30t chain ring as well and the same Center of Gravity at 650 above the BB, since that affects the anti squat greatly.

What's the correct damper hardware size for the 1001? I found 30x8 is that correct?

That is correct

Re: FM1001 / FM1156 - 135mm frame
Does anyone have some numbers regarding shock pressures, does this frame need lower pressures? I've set up my suspension yesterday and my shock pressure kinda feels low, I'm running a RockShox Deluxe Ultimate with Megneg (said to increase required pressure by about 20%) and for 30% sag with my 85kg rider weight I put only 180psi into the shock. Does that sound right? Not that I made a mistake during the Megneg installation

No, I run 185/190 psi on my Super Deluxe Ultimate. I will be adding the megneg (maybe this weekend). Make sure you didn't cover any of the hole in the new can with the orings or red bands. Curious to see what happens after the install.

Finally first ride today, some minor adjustments to be made (brake lever angle, saddle position, one more volume spacer for the fork) but that's it. Bike feels great, size is perfect for me. Suspension also feels very good.
If anyone's interested in final specs, I can add those.

Yes please, that looks great, well done! Specs and components if it’s possibile

Re: FM1001 / FM1156 - 135mm frame I am starting the build of a FM1001 for my wife. The painted frame has just arrived :-).

Re: Carbonda fm936 Thoughts New to the forum, but lurking a long time  ;)

Here's some pictures of my Ican S3
Posting in the FM936 thread, because the S3 isn't available anymore and as the front triangle and geometry are equal to the FM936 I wanted to express my love for this bike here  8)

Eventually bit the bullet last year based on the experiences here on Chinertown as well as the 150+ replies thread on MTB-news.de
I built mine with a XC/DC use in mind. 130mm fork (previously a Lyrik, now a 2023 Pike Ultimate). Suspension is where I've spent the money, the rest is fairly budget-minded or sourced from closeouts.

This thing rips! I also own a 2021 Specialized enduro as well as a gravel bike. So it's been built to fill the gap between the two. And I wanted a bike that could still handle the descents; and it does just that. Enduro confidence on a short travel bike.

The build:
Rockshox deluxe ultimate shock
Rockshox Pike Ultimate 130mm
Aluminum Wheels from slowbuild.de (=Newmen rims) and DT-swiss 350 hubs
Rimpact insert in the rear wheel
Wicked Will tires (Tubeless)
SLX crank with inpeak powermeter
Deckas 30t chainring
KS Lev integra dropper
Fabric Scoop flat saddle
Deore 11-speed shifting (recently changed to a ZTTO cassette)
Deore disc brakes
KMX X11-gold chain
Race Face Atlas stem
Brand-X carbon bar
ESI Chunky
Time Atac MX6 pedals
