CAM Biker roof carrier, 1 bike review

A simple single-bike roof carrier that clamps to crossbars up to 48 mm (1.89 in) across, fitted with two hand knobs and stated to suit all bike models.

Our conclusion The right answer if you already have bars. If you do not, price the bars first — they, not the carrier, are the real cost.

CAM’s 1231 is the plain, cheap way to put one bike on a roof you have already equipped.

What the manufacturer publishes

Adaptability to roof bars with a maximum bar section of 48 mm (1.89 in). Two hand knobs for fitting. Capacity for one bike. Adaptability stated for all bike models.

The crossbar question, which comes first

A roof carrier is half a purchase. It clamps to crossbars, and those are a separate system sized to your car’s roof type — bare roof, raised rails, flush rails or fixed points. On many cars a pair of bars costs more than this carrier. Establish that cost before deciding between roof and towbar.

What 48 mm (1.89 in) covers

Most factory and aftermarket bars fall under it, including the wide aero profiles that some older carriers cannot clamp. Measure yours at the widest point.

The things roof carriers do to you

They cost fuel at motorway speed, they need a bike lifted overhead, and they add well over a meter to the vehicle height. Car parks, drive-throughs and low barriers are where roof-mounted bikes are destroyed, and it happens to careful people.

What is not published

A weight limit and a frame diameter range. On a single-bike carrier with a fork or wheel mount that is less critical than on a towbar rack, but it is an absence worth noting.

The questions riders ask

Will it fit my roof bars?

CAM states adaptability to roof bars with a maximum section of 48 mm (1.89 in). Measure your bars across their widest point before ordering — square, aero and round bars all differ.

Do I need roof bars already?

Yes. A roof carrier clamps to crossbars, which are a separate system. On a car with open roof rails, a set of bars often costs more than the carrier itself.

Our score

7.5/ 10

The right answer if you already have bars. If you do not, price the bars first — they, not the carrier, are the real cost.
