REAR8637 - Atera SIGNO RTD 137cm black aero-profile aluminium bars - RETURNED

£114.95
RRP:
Code: REAR8637

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.

These bars will fit most popular vehicles with flush mounted roof rails, making them superb long term value.

Our Best Buy roof bars for vehicles with flush roof rails!



Atera's SIGNO RTD aluminium bars are sold as a complete package, ready to fit. They're our Best Buy for cars with flush mounted roof rails. 3 reasons: (1) The aero-profile aluminium bar is the most user-friendly profile available anywhere (2) The innovative feet and clamps have been tested and approved for use on well over 50 different vehicles, and more will be added as time goes on; other flush rail systems usually require a different adapter kit for every vehicle (3) These good looking bars exude quality, with numerous smart features, including a torque tool tightening system that's really easy to use.

We've watched the development of Atera's aero-profile over several years and have seen how 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 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:

  • The quality of the aluminium, and the plastic mouldings, makes these bars a pleasure to handle
  • There's real attention to detail. For example, the slots under the bars, which the feet slide in, also need to be filled to reduce noise; Atera's SIGNO RTD bars have automatic adjusting covers for the part of the slots behind the feet
  • The bars are tightened on with a long torque tool - long enough for your hand to remain outside the bar, even on the narrowest setting. You turn the tool until it clicks - then the bars are tight enough
  • The end caps slide down to allow access to the T-track slots - a very crisp and smart solution
  • Weight: 5.5kg for two bars. Note that the stickers on the base of each bar show the weight and maximum load carrying capacity for each single bar; double these for two bars!
  • Load carrying weight 100kg but please be guided by the maximum permitted roof loading limit of your vehicle!
  • Roof bar dimensions: 1370mm long by 79.5mm wide by 27.5mm deep
  • The 'T-track' slots use 20mm x 20mm adapters - the same as CRUZ, Thule and Whispbar aluminium bars
  • Locks are included
  • Supplied as a pair
  • 3 year guarantee
  • Made in Germany

Colleagues here who've been using SIGNO RTD 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.

Delivery charges and arrangements:

We charge a contribution towards delivery costs, depending on what you order, where you live, and how quickly you want the goods.

For most UK addresses, the charge for our Standard three to five day service is £6.50 (£14.50 for orders including a roof box) and our charge for Express Delivery (one or three days) is £9.50 (£19.50 for orders involving a roof box). AutoSock, shoe chains, RUD i-Sock, and small spare parts, are charged £3.95 (Royal Mail Tracked), £4.95 (Royal Mail Express Tracked) or £5.95 (courier, usually Express Delivery).

There are different charges for any delivery including a sea crossing, and deliveries to Skye - we will contact you with a quote on receipt of order.

Orders for Express Delivery need to be received by 4pm.

When will my order arrive?
There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Express Delivery orders placed on a Friday should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday should be delivered on the Tuesday or Wednesday.

What about Next Working Day delivery? 
We have offered a reliable Next Working Day service for well over 20 years but, due to the pressure on the couriers caused by the coronavirus crisis and the huge increase in online shopping, we can no longer be confident about the delivery date, which is why we now call the service ‘Express Delivery’.  Many Express Delivery orders will arrive on the next working day, but some will arrive on the second working day, or be split between these two days. So-called “split deliveries” happen when the couriers do not have enough trailer space for everything that should be moved around the UK, so they will load what they can, and leave the rest for the next trailer.

Is my delivery day guaranteed?
No retailer or courier company can ever "guarantee" a Next Working Day delivery. As well as split deliveries, all courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.

Do I need to be at home?
We are very flexible with our deliveries and will aim to deliver to an address which suits you – this does not need to be your home address. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.
