Robert S.wrote a review of Thule Transport T2 with STL2 Lock - 2 Bike on June 6, 2011
Sturdy and simple to use. Bikes go on and come off in a matter of seconds. No worries about carbon frames being tweeked with this rack. Strap down the back wheel and cinch down the front tire arm and you're good to go!
Last rack you will ever buy. (Coming from a guy with a substantial investment in a Yakima hitch rack that has now been replaced.)
