Qilong is the brand of Ningbo Qilong Bicycle Industry Co. Ltd., a manufacturer of bicycle components based (inevitably) near Ningbo and founded in 1993.
Their artfully over-designed web site helpfully promises that ‘Qilong will ride the wind and cleave the waves’. They seem to be going to do this by producing the usual extensive range of derivatives of the various Shimano Tourney models. I can certainly see some of their weightier, pressed steel, models having little difficulty with cleaving the waves, but riding the wind may prove more taxing.
The web site also shows derailleurs branded ‘Dingli’ - which has an alluring ring to it.
