Hayes’ CX mechanical disc brakes for road/cyclocross bikes become a complete lineup, topping out with a drastically lighter CX Pro.
We’ve reviewed the current CX-5 and loved it, and it gets a lot of love on OEM spec from brands like Ridley, Independent Fabrication and many more. But it’s not the lightest hunk of metal on the bike, so we’re pretty stoked to see it’s been on a diet.
The CX Pro gets heavily machined to drop a lot of weight. This is a very early prototype, but compared to the CX-5 there’s a lot of missing material across the top section, a new vent over the pads and a deep hole on the bottom. The mounting plates also get shaved thinner with a bit of material reduction leading up to them. Lastly, it alone gets a sweet alloy barrel adjuster with lock ring.
UPDATE: They’ll also offer Comp and Expert level CX brakes, with the CX Expert replacing the CX-5. The latest word from the Hayes folks is that only the Pro gets the additional machining and the Crosshair caliper positioning system, so changes to the other two remain to be seen. The rest of the post has been updated to reflect this update. More pics after the break…
A machined port gives the pads some breathing room.
An easily adjustable pad contact bolt helps keep things centered.
Crosshair caliper positioning system makes set up a breeze.
A heavy dose of drillium is applied to the bottom, too.
Retail isn’t set yet, and aesthetics may change a bit, but all three should be available in the fall. Weights aren’t final either, and we weren’t allowed to weigh this sample, but it feels much, much lighter than the current version.
