Carbon bottle cage

The Cirrus Pro Carbon from Forza is light, strong and looks the part, as well as keeping bottles secure and quiet.

It's a full carbon monocoque build, weighing in at a shade over the 28g quoted (30g on my scales) which makes it a very light bottle cage, if not the absolute lightest available. The pleasingly clean, simple aerodynamic lines and low key silver graphics will quite happily adorn any carbon frame, without detracting from its looks.

The Spin QuickLight bottle cage is full carbon and very lightweight. Ours hit the road.cc scales at 28g.

A super-strong stub stops your bottle slipping out the bottom and an equally tough lip at the top prevents it jumping out. I tried with all the power in my thumbs to push each of them out of place – I can get quite destructive in the name of testing, me – but they stayed completely solid, so holding a 500ml or 750ml bottle in place is no problem.

An ant's jaw. Huh? That's what Arundel reckon their Mandible bottle cage is like. It's strong but light. Like an ant's jaw.

This one had me a bit peeved... but more of that later. First things first, the Comtat Ultra-Light Plus carbon bottle cage is light. Ultra light. The test version came in at 20g on the road.cc scales (1g lighter the claimed 21g on the site). And it's cheap. Well, at £24.99 pretty damn cheap for a carbon bottle cage. Comtat has a price-to-weight comparison on its website, and it confirms that it's, erm, cheap and light.

At first glance, the SEAM carbon bottle cage is a stylish-looking and well-finished piece of kit that would look in keeping with many a top end carbon frame. The carbon weave construction shows through the lacquer coating and the neat SEAM carbon logo looks understated and classy.

Blackburn's Camber full-carbon water bottle cage is lightweight and strong and it does its job really well.

The mouth is large so getting your bottle in there is easy even when you’re riding fast over a rough road, and the side ribs flex slightly to provide plenty of grip. The lower cradle stop might look a bit fragile but it’s actually super- sturdy while a lip at the top stops your bottle jumping out if you hit a big bump or pothole.

Comtat's Ultra-light Carbon Bottle Cage certainly lives up to its name, weighing in at a mere 26g. The cage is constructed of a lacquered 3K carbon weave, which results in a high gloss black finish with the carbon weave showing through and the Comtat name picked out in white script.

From a purely aesthetic viewpoint, it has a classy, expensive look and finish that would complement any frame, but will no doubt appeal to those with carbon frames in particular.
