The crew at Shanghai-based Factory 5 are some talented folks. They’ve been working on designing, developing and fabricating track bike goods in China. For them, it’s actually quite an easy task because they live just miles from the factories. One of their recent developments is this precision CNC milled, intricate dual-plane lattice cutout, prototype 7075 aluminium track chainring that weighs less than 80g.

So solid guys! I’ll post more once they’re available.
