Pre tariffs you could get a whole Carbon bike frame from CN (including stem, handlebar, fork) for $500.

And while I'll give that there was variety between vendors, some of them were doing sophisticated layups with multiple grades of wave that withstood a torture tests far beyond the ANSI bike tests.

In fact you could argue they were overbuilt compared to Western brands (at a cost of 100 - 150g) since they didn't want to deal with warranty claims.

Truly amazing, cheap, good quality mass market carbon products.
