Prime Primavera Aero Carbon Handlebar
£149.99
Prime's new Primavera Carbon Aero Handlebar is, like its forerunner, a great upgrade option at an attractive price. The drop is slightly shallower with a more ergonomic shape that's excellent for sprinting, and the price is still very good.
Prime says the new bar is 13% lighter, 29.5% stiffer vertically, 11% stiffer horizontally, and 21.4% stiffer rotationally. Overall, it's apparently 20.6% stiffer with 16% less deformation.
Stronger riders may find this new model gives them a slightly more solid base for big efforts, but the important thing is that Prime hasn't ruined the bar by making it harsh.
The road buzz that can hamper stiff carbon components isn't present here, even with gloveless hands resting on the bare carbon of the aero top section.
The drop section seems to be a bit more angular than the previous model, which helps with getting a tight grip of the drops when opening up a sprint.
The shape gives a tight and stable hold on the bar that really helps you get planted, though one knock-on effect is that the drop transitions into the flat end very late.
Installing the bar is also pretty simple. Large holes for the cables make life very easy – especially if you're installing hydraulic brake hoses with mechanical shift cables – and there's a hole at the back of the clamp area for electronic shift wires heading through the stem.
Overall, this updated aero bar is still light, still stiff and still a great deal.
