Dead Winow FS030.  did this last night on a 2' drop at speed.  Going to end my ice bike season a bit early this year.  Pieces of junk most of these china bikes are.  There's no overtravel limits like all other commercial brand carbon bikes I own.

Thinking about building a custom Dengfu E06 e-fat bike full squish.  Anyone here done something like this?

TanTan'd again.  My fifth TanTan build, my seventh frame in total (sold two new unbuilt) since 2018.  Four frames have had issues - not minor ones either, including one cracked frame. 

This one takes the cake.  I should have learned my lesson with this china crap and bought a name brand to replace my cracked Borealis crestone but I figured I'd roll the dice since I badly wanted a frame to accept a 5.05" rear tire.

Well, my seraph cs197 fat bike frame brake mount out of spec.  The hole pattern is 27mm on center where the standard is 34mm. 

Throwing this out there.

Good luck to you all, in your builds, I am absolutely done with dealing with TanTan for any frame needs - after they fix my issue.  Any money I "saved" by going cheap on a chiner frame+fork+paint vs just getting something "name brand" even if it was made in china, is now out the window in lost hours of specifying, ordering, and assembling and dealing with issues.  There's a definate lack of QC/QA over at TanTan and it shows.  It's been that way for me since 2018.  Highly recommend you pass.  You might get lucky with your sample, but for me, 50+% of the time, you'll come up snake eyes.

That's why I use centerlock I forgot to mention that my rotor offset differences were on CL hubs.

over 20 carbon wheelsets here - most all all DT350 hubs - all 6 bolt.  Never stripped out one even after repeated rotor swaps.

I used FM to PM on a medium, with XTR M9000 brakes, and the brake actually touched the seat stay.  I had to grind the brake bolt to clear on the Medium FM199.  Not something I was happy with.  I was getting terrible harmonics with the rear brake set up and in the end, I had to install the caliper flat mounted with a 140mm rotor.  I tried many many combos of rotors, calipers and cleaning and could never get the harmonic squawking to go a way with a 160mm rear setup.

Curious If anyone has sampled one of these yet
Looks a shameless fox knockoff wondering if that goes for the internals as well?

Anyone test pilot one?

no way is it going to be a fox knockoff internally.  You will get what you (we) pay for.  Not knocking it, I may try one on my next 140mm build  It's getting too expensive to keep funding 5k~6k bikes.  I need a heavier bike for slow family rides, this may do the trick.

Flyxii rims?

No

What's the bug on both builds?

I had a bit of clicking on my large frame, especially while locked out and cranking up the hills.  I just needed to go thru the bushings with a fine tooth comb (and grease and lockout).  They're both whisper quiet now except for a bit of cable rattle on the bumpy downhill rides in the downtube.  I'll put in a nerf ball to fix that.

Overall very happy with the price (and the quality with respect to that price)
