I know for my built for torque specs I used a lot the repair manual from original frame design company (Scott), maybe the same exist for your frame. A quick search I found this:

I love the front brake, great feel, rear got a whole lot better but doesn’t have the exact same feel, like weaker bite.

I would agree with you, 6th cog would probably still be somewhat offset. Regarding chain coming off on back pedaling, hasn’t happened to me but I don’t recall being in that scenario either

The 55mm chainline looks real measured with a 3mm off set. However at this offset and with 32t ring I seem to have some rubbing under load condition as my frame is scuffed at the chainstay/ring area. And there is no way you can go bigger than 32t with 3mm offset, or I put the bike together wrong, which is entirely possible lol
I’ll add pictures later tonight.

In the wild.

Did a few more miles, bike is so pleasant to ride. I am also impressed by the simple handle grips I have, foam, great level of comfort! They are fragile though but such a low cost that I don’t care, I’ll simply replace as needed.
The bolt on steer tube compression fitting is rusting already, I will replace by titanium one and be done with it…

First ride today
The good:
Bike feels super responsive
Riding position is confortable
ltwoo groupset is good
front brake feel is great
Handle grips feel is great

The “need work”
Rear brake feels weak, probably need a good flush to remove any air bubble
Shifter feel is good but I need to work on positioning

The need upgrade/replacement:
Toseek bottle cage broke on first ride
Pedals are too small

Thanks!

Setting up and adjusting the Ltwoo was a breeze. The shifting is nice and crisp, the only critic would be that the throw to the upside is a tad long but may just be a matter of getting used to it.

End of this year my daughter should be tall enough for a 24”, I will probably built her a bike using same type of components. I am not sure how quality is on the cheaper Ltwoo stuff though.
Overall I am really pleased with all the components I got but only time will define if it was good value. Fit and looks have been exceeding my expectations for sure.

I finished mine (mostly) as well.
Some minor things like brake fluid / air in the system. Haven't ridden it yet due to being sick all the time.

Weight is around something around 9.8kg - I don't have proper scale, only one intended for luggage.

That’s a nice looking bike and higher specs that mine! Looking forward to your feedback. I should take it on its maiden ride this weekend. Actually thinking of taking Friday off to go ride!
