Ralf Bohle, the German company that owns the Schwalbe brand of bike tyres and tubes, has started up a new factory in Vietnam together with an Asian partner, complementing its Indonesia facility. The initiative is described as a response to strong demand for the company's products. At last month's Eurobike show, Schwalbe presented a revolutionary double-chamber Procore tyre for mountain bikes, with different levels of air pressure, that shields it from snake puncture and other accidents.
