I bought this cable to secure two bikes and all four wheels to my car while mounted on a Thule T2 rack, and it's just right. I like the sliding lock pin on the cable... very useful for perfect cable arrangement. Does not come with lock cores though. At $39, that would earn it 5 stars.

I shopped the competition's racks for a good hitch rack that would accommodate 29er mtb wheels and not hang the bikes by the frames, and this one stood out as the best deal. It's stable and easy to use, and the folding mechanism is solid and helpful, both upwards and down for hatch access. I use a cable lock to secure all four wheels and both frames, instead of the Thule designed locks.

My only wish is that for those of us who like to use cable locks, rack companies would incorporate a small metal loop or something on the rack, through which to pass the cable, so that the rack is secured to the car as well. I know Thule sells a locking pin, but using a cable could do the job, or provide backup. Maybe I'll have a friend weld one on.

Concerning the post below about this rack not being 29er friendly... my front wheel is a wide rim Stan's Flow, with a 2.55" WTB Weirwolf mounted. It takes some wiggling to get the arm over the tire, but I can get the arm to engage 3 clicks without releasing pressure from the tire, and am pleased with how it holds. It is certainly 29er friendly, for tires up to at least 2.55".

I'm very pleased with the rack, and recommend it. Easy, durable, well-designed.
