Have been using this Bike carrier for almost a year now. I have been transporting mt DH Bike all over and i never had a doubt in my mind that i would lose my bike on the road. Just have to check the clamp bar for the down tube after some time just to make sure that everything is working fine. But it tend to rub against your down tube when it clamps on. other than that its a good and damn reliable product from Thule. If you have a roof rack i recommend getting it. Its better than losing your bike when a car hits you from behind. Have a great ride ahead!!
