For anyone interested, I mailed Tantan. These are the Torque values for the GR201

handlebar=8-10nm
saddle clamp=4-5NM
seatpost clamp=8-10NM
rear hanger=3NM
Bottle cage hole=3NM
thru axle =9-13NM
headset expander=8-10NM

In that list I'm assuming the "headset expander" is the compression sleeve inside the steerer tube?  I torqued mine to 8 nm with and without carbon assembly paste and it just pulls out with minimal torque on the stem cap.  I'm getting a longer one from Amazon tomorrow. But if that doesn't work, any other tips?

My stupid question for the day: Is that gap between the Lexon dustcap and your bearing just there to show the bearing and plastic ring in place? Also, you need the pinchbolts loose when you tighten down the top cap to pretension the bearings. But you probably know that. I also thought carbon steerers need to be cut higher, so the pinch bolts align with the compression sleeve inside.

I just received my frame yesterday but my Lexon bar is still awaiting a flight from China so I'm thinking this through myself.

I put my order for a GV201 in on Black Friday. Now I'm thinking through my build components. I'm thinking about a wide range 2X setup using Shimano Cues, but the Cues brakes apparently are designed to only work with 160mm rotors and the frame is for 140mm rotors. Usually a brake set comes with  a mount plate that can adapt to either but the Cues does not come with that adapter and I'm not sure if those are standardized or unique to the frame and/or brakes.

I'm not sure that 1 mm more space will be enough. How much clearance is considered to be safe?

Many people don't have problems here, even with 46T chainrings, but my case is different, which is strange. This is my first build, may be I did something wrong, but I don't understand what exactly. I would be very grateful if someone could tell me. I put a 1 mm spacer on the shaft between a nut that holds a power meter and a bottom bracket. The bottom bracket model is Token BB47V24, installed without any spacers.

The chain doesn't go here. It's the left side of the chainring if you look from the drive side.

Now I see it. I thought I was looking at the downtube clearance when it's the chainstay instead.

I've just received my frame and started building it with Magene P515 cranks and Wuzei 44T chainring with 3 mm offset. Even having a 1 mm spacer on the drive side the gap between the chainring and the frame is extremely narrow, less than 1 mm.

What do you think, is it okay to ride like this, or should I add another spacer (is it safe?) or get another chainring?

What does it look like with a chain on it? My guess is that the chain will not even be able to get in there, will rub, or be very close to rubbing.
