Atera's low noise, low drag aerofoil bar profile trumps all others for useability, quite apart from its 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.
Instead of clamping around the whole raised rail, these bars fit onto the lip on the top of the rail. The roof rails on this car are a hybrid style - they are raised off the roof, but they have a flush mounted roof bar profile.
Please check the load that your roof rails can take. We are aware that some models of MG ZS are fitted with rails that are not load bearing.

Atera's SIGNO RTD aluminium bars are sold as a complete package, ready to fit. We rate them as our Best Buy for raised rails, flush mounted rails and - as this vehicle uses - a 'hybrid' combination of these two types. This is because (1) the aero-profile aluminium bar is the most user-friendly profile available anywhere, and (2) they're good looking, exude quality, and have numerous smart features, including a torque tool tightening system that's really easy to use. Hybrid roof rail systems - an important note: This car has raised roof rails but, because these have a flush-mounted roof rails profile, with a protruding lip, they can use these RTD bars, which are usually used only on flush-mounted roof rails. Atera RTD bars will (uniquely) fit to huge numbers of vehicles with flush-mounted roof rails, but they should not be used on most raised roof rail systems. In summary - please check our database very carefully before trying to fit them to any other vehicle with raised roof rails! We watched the development of Atera's aero-profile over several years and saw how they were 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. At the time, all other aerofoil bars (apart from Yakima's) were only quiet if rubber strips were pushed into their 'T-track slots', rubber which needed to be removed when accessories were fitted. Thule solved this problem by anchoring their rubber strips on either side of the slots, but this makes T-track accessories much more difficult to fit (and some accessories, even Thule ones, will not fit) and fitting the rubber strips into Thule bars is not easy. So we are confident that Atera's aero-profile system is still the best, because it's the easiest to use, and it's quiet. What's the science behind this success? See the second picture above. In summary, the WindBarrier strip creates small swirls which form an air cushion 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:
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. Alternatively, we have sets of straps available that are perfect for the job and are really easy to use. Yakima make some excellent Bow/Stern tie down straps and 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 properly 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. |
