M5 x 10 mm flat head, worked for my frame

I originally switched to black screws and washers but I'm looking to swap them out for rubber plugs/grommets to reduce the chance of rust and also weight savings  . I've tried 4.5mm plugs but they are too small and will need to try out 5mm.

Airwolf seems to have earned a bad rep on here and BXT seems to ignore you if you have issues. I'm good with SPcycle, their shipping is ridiculously fast and my last frame from them has been solid, but I find their paint mediocre.  Also I didn't notice the G068. It looks better than the G056 in my opinion. I prefer the seat stay design on the G068 and I don't need fork mounts either. Though it comes in 100g heavier. Maybe the down tube is a bit stiffer? I'll put this one on my radar.

Did you see the geometry on the G068 ? you are not going to be relaxed on this frame even running a 80mm stem. The G058 is a similar shape to the G056 but with a much more relaxed geometry.

I just finished building up a bike using this frame, hit me up if you have any questions. Mainly for commuting but I can easily switch out the tyres for gravel use.

I experienced the same issue trying to build up a Chinese frame using a different handlebar to the stock one. The solution was to ask the frame seller to send me the stock c-ring only and then use my preferred handlebar.

In my scenario, it was clear that the non stock c-ring is much thicker (hence the gap to the frame) versus the stock c-ring which was flatter (and it was also metal).

It will all depend on your setup though as the c-ring typically has a notch which the headset cover connects to so it turns in tandem with the handlebar.

I hope someone can help me with this frame build. I recently purchased the version sold by "Surprise store" on AliExpress. My issue is installing the headset where there is a gap between the lower bearing and the fork and also a bigger gap between the frame and the headcover for the top bearing - this is using the supplied headset. With the top bearing in particular, this sits flush with the frame and when you put the the compression ring on, it sits too high the the headset cover leaving quite a big gap. Any advice is appreciated.
