Atera have taken their time to develop a low noise, low drag aerofoil bar profile, but the wait has been well worth it; these bars trump all others for useability, quite apart from their superb design and looks!
The big breakthrough is that you don't need to plug the slots with rubber strips to keep them quiet. All the details are really well thought out, and they exude quality at every level.

Atera's SIGNO AS aluminium cross bars are sold as a complete package, ready to fit. We've seen their development over several years and know that they've been refined and refined, with a lot of wind tunnel testing, to achieve optimum efficiency - low noise and low drag - despite not having any rubber infill in the slotted channel. Keeping this channel open was the challenge that Atera set their design team. Other aerofoil bars (apart from Whispbar) are only quiet if rubber strips are pushed into their 'T-track slots', rubber which needs to be cut into sections and placed between, for example, bike carriers, and then more rubber added when the bike carriers are removed. You want to leave your bars on your car ready for the next time you go biking, and just slide or drop the bike carriers into them without any need to fit and remove rubber strips? Is speed and ease of use important? Of course it is, which is why the engineering behind these bars is really very clever indeed. What's the science behind this success? See the final picture above. In summary, the WindBarrier strip creates small swirls which form an AirCushion across the surface of the T-track slot, preventing the development of wind noise whatever the driving speed. The design of the ShapeBreak trailing edge also controls the airflow, improving roof bar stability and reducing the downward force. Other features:
Colleagues here who've had the opportunity to use these aero-profile bars to carry their bike racks are very confident that Atera have nailed it! Most of Atera's roof bars and accessories business is with the Original Equipment market, i.e. direct to the car manufacturers, where major customers include Audi, BMW, Daewoo, Chrysler, Fiat, Honda, Hyundai, Mitsubishi, Mercedes, Opel, Porsche, Smart, Subaru, Suzuki, Vauxhall and Volkswagen. Atera’s reputation therefore speaks for itself and, (probably needless to say), their products are manufactured, city crash tested, TÜV certified and quality approved to the highest international standards including DIN ISO 1135, DIN ISO 75302, and IAF ISO 14001:2004. |
The aim of this note is to persuade you that kayaks should always be tied to the carrying vehicle at both bow and stern. Untied kayaks have, in our experience, the greatest potential for a roof bar or kayak carrier failure. The massive forces that untied kayaks can generate have even been known to snap roof bar fixing bolts with the result that a complete assembly of roof bars and kayaks has ended up on the road. We know that this has happened with almost every brand of roof bar, and regardless of whether the kayaks are on a special carrier or just strapped to the bars. You need to fix bow and stern lines, probably using the front and rear screw-in towing eyes to get strong and accessible fixing points on the vehicle. Kayak shops should be able to provide suitable 'paracord' for this purpose. It is cheap and readily available online. Alternatively, Thule makes the QuickDraw 838 which we have listed together with every kayak carrier we sell. Please note that kayaks should be strapped to the roof bars, or to kayak carriers, using straps that are suitable for the purpose, e.g. 25mm polypropylene straps with strong buckles. Bungee cords must never be used. Please also note that all roof bar instructions point out the dangers of carrying unsecured long items, as of course do all kayak carrier instructions. If you tie down your kayaks you almost certainly won't experience a product failure. If you don't you may or may not get away with it. If there is a disaster and the kayaks end up on the road, separated from the vehicle, then you were not using tie downs and you have subjected the roof bars to forces for which they were not designed. The costs of sorting this out are yours, not ours, and you may also have difficulties with your insurers. We're sorry to be so firm about this, but "things coming off the tops of cars" is the stuff of nightmares, and we want to do all we can to prevent accidents of this sort from happening. |
