Most Popular Roof Bike Racks for 2012 GMC Sierra

1. One star ding for price. Fairly expensive for a single bike, especially after adding a lock core. 2. The rack works exceptionally well and I'm not disappointed with the purchase. Installation is fairly simple. It does take a bit of fiddling to get the tension down on the rack clamps (connecting it to car) but it is a simple affair, and I'm able to move it between an aero rack and a round rack with out adjusting the tension. The sliding tray in the rear is a bit sticky, so if you carry bikes of different wheelbases, you may need to add some lubrication to the tract. Front wheel locks into place (I've used 700x25 and 29x2.3) simply, and the clutch in the tension wheel is a nice addition. It would be nice if there was a quick release button (like in times past) but it spins fairly quickly to unload. The locking whip is a nice addition. I have been able to rout it over the chainstay on both bikes. However, it is too short to route around chainstay and wheel. I'd prefer to include my rear wheel inside the lock. Overall, I'm very happy with the product.

I bought two of these, they work great, good the bikes very solid and I'm confident using them over hundreds of miles. etrailer.com is my go-to for tracks and accessories

This is an outstanding rail. And is the second one that I have bought. For a matched set. They were great on my BMW roof racks. Outstanding product as always. Thank you
