Folks,I'm scouting around for rim upgrades and quite interested in the 18" Breyton GTS. Could you kindly advise where I could such rims (ori, not reps) in KL/PJ (...or SG) and how much would these cost?Anything else I need to be aware of....e.g. built quality (heard it's from China...hence less durable?), weights, etc.?Many thanks in advance.
