Our review

The RXL riser is ultra-light, a great shape and very reasonably priced for what it is

Bontrager are owned by Trek, which gives them access to their OCLV (Optimum Compaction, Low Void) carbon fibre technology. It’s well used in the RXL which, at 182g, is impressively light for its width.


Graduated cut marks extend inwards 40mm at each end for accurate trimming, although they terminate in small print reading “Cut by professional only”. We’d be surprised if a professional did anything other than use a fine-toothed hacksaw and a face mask, though. 

There are more handy lines and marks on the RXL too, with a positioning grid on the bulge and a scale on each side near where your controls go to finally end that ‘wonky brake levers’ misery. Overall finish is shiny and smooth, to the extent that you’ll probably want to get the friction paste out to mount the bars up. A textured grippy section at the bulge would be a welcome addition.

On the trail the RXL inspires, with a comfy shape and useful blend of solid feel and buzz-reducing trail damping. Inevitably the price is high, but it’s actually significantly cheaper than most comparable bars and therefore represents decent value for money.
