Profile Design 50a Extensions

The Profile Design 50a Extensions are an aluminium aerobar extension that allows the rider to reach the ideal time trailing position for them. This is beneficial as the rider can reach comfortable allowing them to chase performance. The 50a uses a 50º bend, popularised by the praying mantis position which sees the arms covering the face. The extensions also feature a 7.5mm lateral offset, allowing riders to achieve a narrower or wider position without having the shifters contact. Using the 22.2mm diameter, this extension is compatible with the majority of 22.2mm clamping systems. The pole is designed for cable routing, hence features end caps covers.
