The GIRO AF came out top in a recent product test in the "Auto Strassenverkehr" magazine. (1 = Excellent, 2 = Good, 3 = Satisfactory, 4 = Adequate, 5 = Not good enough, 6 = Failed. The lower the score, the better.)

It scored 1.5 for its concept and workmanship, 1.7 for fitting and use, 1.0 in the driving test, 1.8 in the crash test, with an overall score of 1.5.

Here is an approximate translation of the summary:

• Good results in all areas: The test winner's concept is well thought through. The wheel rail can be adjusted and adapted to the bike. The method for fixing the wheels to the rail also proved to be good, because the strap is equipped with a ratchet, which facilitates the attachment. The frame holder is equally convincing - it fits neatly to any bike with its quick release clamp. It didn't show any noticeable weaknesses during the driving test. The GIRO AF passed the slalom, shaking track and full braking tests with flying colours. Though one frame holder loosened, the bike was held firm.
• The Thule ProRide 591 is also praised but let down because it doesn't include adapters for the wider channeled BMW aerobars (which are made by Atera, so the GIRO AF comes with the adapters!). As with the GIRO AF, the Proride 591 "convinced in the driving and crash test, during which only one holder loosened slightly".

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.
• 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".
