"These carriers are well worth the investment if you aren't confident that you'll be able to lift your bike or tandem to head height without it toppling over.

The BIKE-LIFTS make easy work of roof mounting; one lift can be placed on either side of the car. You slide the saddle into its carrying loop, secure it with the safety strap, hook the handlebars into their securing cradle, and then with relatively minimal effort the bike rises to the car roof. When not in use the upright can quickly be removed for storage in the boot.

It fits both standard box section bars, i.e. 32mm by 22mm, and aerobars. The adapter that connects the bike carrier to the cross bars is available separately, you will need to choose the adapter that will work with you cross bars.
