I recently built up a Yishun FM145 frame. I *think* this is the same frame as the Hongfu 166? In retrospect the FM079 might have been slightly better geometry choice, but working with Yishun was great and the build went really well.
My initial plan was to use the Whisky No 9 fork with 15mm thru-axle, but thrift won out and I will ride the fork that came with the frame. I am using 9mm thru-bolt which seems to work great. This is not a super budget build, but is also not a top-shelf build (Sram Force, alloy Ritchey cockpit); it was certainly more affordable than equivalent other complete bike offerings I have seen from Colnago, Specialized, etc.
I also used Spyres. I was debating mechanical vs hydro, but am very happy with the performance of these brakes (and the ease of setup).
At 7.83kg/17lbs4oz ready-to-ride, this is obviously not a WW build, but it's not heavy enough to be able to use it as an excuse for being any slower. (It is 9oz heavier than the similar+spec rim-brake bike it replaced, which is a bit better than I was expecting.)
