Wow, there is definetly nice stuff coming out of Taiwan. Always has been, really. They just seem to be on the cutting edge of everything to do with bikes. Eight kilos (17.6 lbs), and with disc brakes ! Was the JBC frame manufactured as an MTB frame ? That is probably the most exotic "hybrid" build that I have ever come across, except for that Madone conversion with Zipps that is floating around the Net.
