Profile Design aero bars are renowned for their adjustability. They're also easy to assemble, with newbie testers mounting the bars to their bikes in less than five minutes. In terms of pound spent for the lightness of the bar, the Legacy bars perform well. At 475g and £59.99 this is a great combination; with other products both costing and weighing more.
The bar extensions are fixed in their housing, which means they're restricted to a relaxed overhand grip. There's a range of lateral mounts for the arm rests and you can rotate each one in so it aligns with the angle of your forearm – a great feature as it stops your arms digging into the metal housing of the arm rest. It offers great value for money and is very versatile.
