Thule ProRide XT

The torque limiter dial is what sets this apart from other roof-mount racks — it lets you clamp carbon frames without guessing how tight is too tight. At 11 lbs it adds minimal weight to your roof. One-hand mounting makes loading straightforward. The 44 lb limit means standard bikes only, and remember that roof racks add wind noise and reduce fuel economy. I recommend this to riders with carbon bikes who want the peace of mind that comes with a torque-controlled clamp.
