I'm getting tired of bike shops behaving like they went to school and had an education. Sorry, I meant bike shops shitting on Chinese bikes, as if not everything was manufactured there.
I've put 1500km on a VB168 over a couple of months, if you build it well and it's your size, it's a very nice, and very fast bike. I've ridden road bikes for well over a decade and am a fairly decent rider. As you know, dont expect plug and play, you may have a bit of debugging to do, but i'd argue it's worth it. The VB177 is built better (EPS moulding). Winow has a very nice aero frame (FM368). EPS moulded. Long teng has 1 that looks like the 168, but with EPS moulding (268). They all cost about the same. I'm in the process of buying 2 of each. The Winow and Long teng can take 32C tyres, which the others can't. If you plan to commute with it, i assume your asphalt is bad / riding style aggressive (jumping curbs and what not), in which case it may be worth considering.
