Profile Design 43a Extension
The Profile Design 43a Extension is an aluminium aerobar extension offering a neutral wrist angle. The extensions also feature a 7.5mm lateral offset, allowing the poles to be rotated so that they are the most comfortable for the rider.
The 43a was originally the T3 extension, hence has a performance-proven past. The 43º angle allows PD to provide a wrist relief, where the bar goes down before rising at the bend, allowing the rider to move up and down the extensions.
Using the 22.2mm diameter, the extension is compatible with the majority of 22.2mm clamping systems.
