Our review

Sophisticated internal-clamp aero design but at a massive weight and wallet cost
Skip to view product specifications

The Vision Trimax Carbon CSI clip-ons are gorgeous looking, high-comfort aero bars, but their overcomplicated design means they cost a fortune and weigh a ton.

They come with riser spacers, and the adjustable, drooped pads on tapering composite cups are both comfy and secure. The neat flip-out-arm socket tool for the drag-reducing internal clamps that secure the extensions also seems cool at first. Then you realise you’d be screwed if the bars came loose on a ride.

The CSI extensions use a veneer of carbon over an alloy inner tube and, combined with the hidden mechanism and metal end caps, it means these ‘carbon’ clip-ons weigh twice as much as the lightest bars out there. All the complexity makes them very expensive too.
