Haibike Challenge RX 2013
State-of-the-art shifting technology at a competitive price. Relatively heavy. Only five sizes available.

A carbon racer with Di2 is currently hard to find cheaper. The price of € 2,700 is also possible because Haibike shares the development costs for the frame with its sister brands Koga and Lapierre, which offer similar models on the same basis. With the slight curve in the top tube and internal cables, the frame looks elegant and clean; however, it is around ten per cent less laterally stiff than Koga's identical Solacio - possibly an indication of manufacturing tolerances. For most cases, however, the riding stability is easily sufficient. And the manoeuvrable bike is a pleasure to ride. The 25-millimetre tyres provide noticeable damping and the aluminium seat post also offers good suspension comfort. The simple Shimano brakes and cranks fulfil their task reliably, and the heavy Mavic wheels are considered durable.
