It's around 4-5mm with flip-chip in lower position. If i flip it the yoke will be even closer.

Hi Bos...I think you are looking for the "effective seat angle" which wouldn't be 65 degrees.

If Mousey took a straight edge or a level and lined it up from the center of the bottom bracket to the seat mount...and then put his angle finder on that straight edge...you would get the effective seat angle.

Edit - seat would need to be at the normal riding position...not the slammed down dropper post position.

And so i did. The level finding thingy showed 71,85 or thereabout... Seat height from bb to the rails 75cm or top seat 80cm

Managed to get some dirt on the bike today. Still happy. Needs some fine tuning, but will get there.

hello again,

Finally i got my wheels. Bike built to 99% - ready to test ride. I finished in the evening so photos are made with bad lightning - will do some more in daylight. Bike feels great, i went for RS superdeluxe ultimate shock and Ohlins RXF 36 EVO at the end.

here are the specs:
crank - slx 32t 175mm
rear mech - slx 12s (10-51)
shifter - slx 12s
bb - xt
rotors - xt 203mm
hubs - xt micro spline
rims - WTB ST 30 Light 29"
brakes - slx 2piston (gonna upgrade front brake to 4 piston probably9
handlebar - ritchey trail raiser (10° back sweep - I know, i bought it without thinking..)
stem - 50mm (krsec - aliexpress)
seat - proloq (aliexpress)
seatpost - x-fusion manic 150mm 34,9
pedals - rockbros (aliexpress)
tires - Maxxis DHF 2.5 and DHR II 2.4
fork - öhlins rxf 36 Evo 29"
shock - RS superdeluxe ultimate 210*50

Bike is size L and feels great (I'm 1.88cm). Fork is buttery smooth (if anybody is interested) as i read a lot of reviews how bad it is - i haven't ridden a better fork, and i have ridden Marzocchi bomber (yes i am that old), Marzocchi 66, RS Boxxer WC, RS Pike RC, and this fork is the best one yet. I don't know if it's the 29" wheels or is the fork actually that good. Also the rear shock - the lock out function makes this bike almost like a hardtail (sag set to 30%), you can accelerate almost as on a hardtail... anyway, I only did short runs around the house, run some stairs - usual stuff.
 
Bike now weights 14,00Kg with tubeless system and you will agree DH tires. So if anybody wants to get it in the 12-13Kg range it shouldn't be to hard.

So far i'm happy with the build, still missing some bolts for brake adapters, stem spacers and cap, but the ride is great and that's what matters. Will follow up with info if anybody is interested.

Bottle holder really is too high, but i'm not really comfortable drilling holes in a carbon tubing... Maybe epoxy would help?

Another question, top shock mount is from specialized spec standard 6x20 but this frame has an opening of 21.6. Probably the best thing to do is to machine custom bushing to have a tight fit, right?

hi everyone,
I'm new on this forum and want to share a few info about this frame. Ordered in on december 23. recieved last week with DPD shipping or XDB whatever you call it - no tax had to be paid.
I had all the components (bar wheelsets) waiting at home so i could start assembly asap... but - they speciffy 190*50 or 160*50 rear shock - i went for 190*50. My frame is L size. I installed the shock and let all the pressure out to see where it stops - shocker... when rear triangle allready hit the seatpost the shock still had 10-12mm of travel left... So i fiddled around with caliper/measure tape and figgured it out that min length after the shock is compressed is 160mm and max is 210mm - so the only shock that is suitable in my opinion is 210*50mm - with that you have exactly 150mm of travel on the rear wheel. So the info they give out on the aliexpress seems to be wrong or the old design of the shock fork. anyways, i now ordered 210*50 shock.

The frame is really well made - of course i ordered all the oem items swus231 posted in #31 post - thanks! i did a hack paintjob and now waiting for the proper shock and wheels to check the ride. There are minor surface (I hope) dents/holes which the black paint hides really well so consider that when chosing your color choice.

Frame weighs 2190g painted - without seatpost clamp and chainguide.

Edit: i forgot to add, the headtube angle with 210mm shock and 160mm fork is around 65°
