1. How many bikes?
If you want to transport two bikes, you need the Thule 9002 Raceway 3 Bike rack. The distance between adjacent bike cradles is too small for full size bikes to be transported side-by-side without touching and bumping into each other. Two bikes on the first and third cradle of the 3-bike rack will do just fine. The 2-Bike cradle is only good, if you are planning to transport one bike only. There is no way to put three bikes on the 3-Bike rack without bumping and scratching them on your way, unless you use lots of extra padding on various parts of the bikes. The padding would have to be solidly installed so that the wind would not remove them at higher speeds. Installing the extra padding would also be a very time-consuming process. You don't need that. If you want to transport three bikes, you've better go with a roof bike rack.
2. Installation problems
If your car has continuous plastic cover across the back of your trunk lid, then the lower bottom hook is too narrow ands too short to safely attach to the bottom edge of the trunk lid. Alternative attachments are suggested in the THULE Raceway Platform Fit Guide.
For example, the 2003 Chevrolet Impala owners are encouraged to "Set lower clips/hooks on top edge of the metal bumper struts." That is underneath the car, where the parts are exposed to dirt, stones, gravel, and rust. It also requires that the braided steel ratcheting cables together with the cable cover be bent at sharp angles over a sharp metal parts of the bumper assembly. This is not good, as this type of cable and its cover will be quickly damaged while sharply bent under higher tension.
3. Bike cradle pads
The pads are too narrow for some newer models of bikes with flat top tubes. This requires some soft padding around the top tube to protect it from scratches and pointed pressure - especially with the carbon frame bikes. Such padding increases the diameter of the top tube and results in insecure attachment of the rubber straps to their cradles or to the no-sway cages.
The bike cradle pads and especially the no-sway cage are not soft enough and will scratch or mark the bike frames, especially the more vulnerable carbon frames.
4. The ratcheting knobs
They require a considerable strength to tighten the cables and securely attach the rack to your car.
5. The new 9002XT model
In this model, the two bike arms are separate and separately adjusted. This is similar to the old Saris trunk bike carriers in which the arms had an inward-outward play and were hard to keep parallel. I prefer the one-piece and more solid solution of the older models (and the older model price, as well.)
