Atera GIRO Speed AR2221

The GIRO Speed is a smart and innovative carrier, originally designed for BMW but now available to the aftermarket. The real innovation is in the tightening system where, first time out, you pull out the tensioning knob and turn it until it's just the way you want it, not too tight, not too loose. Thereafter it uses a quick release system. Other manufacturers use a trial and error system, i.e. the user needs to guess the tension required, and then find out whether it's right; there's a real danger of overtightening and then breaking the mechanism.

The GIRO Speed fits standard 22mm x 32mm bars, and all the T-track aluminium bars we sell (adapters are included), and is suitable for bikes with disc brakes. It works with standard 9mm QR forks, adapters are available separately for some thru axes.

As well as locking the bike to the carrier, the carrier is also locked to the roof bars in an innovative way: The carrier is held to the bars with Torx bolts; as the tensioning knob it tightened the holes which provide access for the Torx key are blocked by steel plates - that's superior anti theft protection!

This carrier is part of our "Pick and Mix programme", where there are discounts for multiple purchases of any carrier in the programme, and you can mix cheap and expensive. Change the quantities in your shopping basket (and press "Recalculate") to see what happens! This carrier is priced as low as £74.95.

Our free wheel bag offer

We are giving away free 28" or 29" wheel bag(s) with forkmount carrier orders, while stocks last.

The downside of forkmount carriers is that you have to find a way of carrying what might be a muddy / wet / oily front wheel - a wheel bag is the easiest solution.

We have single and double wheel bags to give away. Order 1 bike carrier and we will send a single, order 2 and we will send a double, order 3 and we will send a double and a single, order 4 and we will send two doubles.

If you have a preference about 28" or 29", please make a note in the 'Order comments' box in the Checkout. If we can meet your request, we will, but stock is limited and we can only send what we have!

These lined and padded wheel bags hold all wheels up to 28" or 29", are made from a highly tear-proof polyester, and include very useful internal pockets, one Velcro and two zipped.

• Diameter: up to 760 mm
• Extra protection at the axle points
• High quality zip
• Includes two carrying handles and a shoulder strap for easy carrying

These are made by B&W International, based in Germany, who we think make the best quality and best designed range of bike carrying bags and boxes on the market.

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.

These are our standard charges; there are usually surcharges for all offshore destinations and some remote postcodes, especially for Very Heavy Items (defined below):

Orders involving a roof box, and Very Heavy Items


• Standard delivery (3 to 5 working days) = £14.50
• Express delivery (1 to 3 working days) and Very Heavy Items = £19.50

AutoSock, and items which are small enough to be posted, e.g. small spare parts


• Standard delivery (3 to 5 working days) = £4.95
• Express delivery (1 to 3 working days) = £6.95

All other products


• Standard delivery (3 to 5 working days) = £6.50
• Express delivery (1 to 3 working days) = £9.50

All orders for Express delivery need to be received by 1pm.

Very Heavy Items

Roof tents and some other items that are very heavy or unusually large are, for safer and more careful handling, best carried by two people.

Very Heavy Items are delivered via the ArrowXL 2-person delivery service. All other products that are part of the same order will usually also be delivered by ArrowXL, at the same time as the Very Heavy Item.

Please note that deliveries from ArrowXL need to be signed for, e.g. by a neighbour if you are not at home, or you can have the goods delivered to a different address.

There is a £25 surcharge for Very Heavy Item deliveries to the Grampian area, Scottish Highlands, any GB delivery including a sea crossing, and Northern Ireland. There is a £50 surcharge for Very Heavy Item deliveries to the Isle of Man, the Channel Islands and the Republic of Ireland. Deliveries to all these places will take longer than normal, sometimes much longer - delivery timings are indicated in the Shopping Basket.

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 (before 1pm) should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday or Sunday should be delivered on the Tuesday or Wednesday. The arrangements for Very Heavy Items are different and are shown above.

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’. Most Express delivery orders will arrive on the next or second working day, but some will arrive on the second or third working day, or be split between these 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.

Payment options:

We take the following cards, and also PayPal. Please note that the entry on your card statement will be from "The Roof Box Company".

Secure payments

Our website is secured by Sectigo (formerly Comodo CA), the largest commercial Certificate Authority in the world.

We offer our existing customers a full "Next Day if possible" spares service, and will cannibalise new stock as required to find you the parts you need.

To find the spare parts you need, please see the diagram below, identify the product codes, then choose them from the list below. If you need more than 1 of any item, change the quantities in the Shopping Basket.

Deciding which bike carriers to buy is not always easy, especially as you may not have had experience of using bike carriers before. We hope that our buying guides provide useful guidance about which bike carrier 'strategy' will be most appropriate for your circumstances, as well as highlighting the best features of particular models. We also have troubleshooting FAQs - for example, some customers struggle at first to fit four bikes onto a tow ball carrier, and wonder whether a different carrier would allow the bikes to be spaced wider apart. (It won't, but we have some good tips which make bike fitting much easier.)

Our bike carriers Exchange Scheme covers roof mounting and tow ball mounting bike carriers only. Rear door mounting / strap on carriers are not included, and nor are roof bars. It allows you to exchange within 90 days of invoice date. Most exchanges are for roof mounting upgrades, or are tow ball carriers with very basic tilting systems being exchanged for easy to use sliding / tilting carriers.

These are the rules of the bike carriers Exchange Scheme:

• You are allowed one exchange only.
• The original equipment must be in "as new" condition, subject only to fair wear and tear.
• The replacement items must be different models from the originals. Not just an alternative colour.
• The replacement items must not be part of a package deal or be from our Bargains section.
• Roof bars are never part of the Exchange Scheme.

This is how the exchange scheme works:

• We charge in full for the replacement items, including the appropriate carriage charge and a charge for any packaging needed for the return of the originals.
• We pay the return carriage costs.
• When the originals arrive back here we refund you for their invoice value, but you won't get back more than the invoice value of the replacements. In other words, if the replacements are cheaper than the originals we won't be giving you "extra cash back".

Please note: we can only collect items from mainland UK.
