Having sold Thule bars, these are the equivalent of the Aero bars, but about £65 cheaper. End caps a pain to fit, the trick is to pull the locing lever forward a couple of mm. Doesn't affect the locking, of the bars to the roof, but the plastic end caps lock on a lot easier.

These bars are very solid when fixed into place, their main let down are their covers with the locks in. I found it very hard to make them fit and you could easily break then when trying to turn the key. Apart from that they are solid, just the covers let them down. Would still highly recommend though.

a nice set of roof bars allthough the plastic lockable end caps could be betterthe set was just what i wanted

Found these roof bars very easy to fit and are very sturdy once in place. My only quibble would be that the covers that go on the ends of the bars are a bit flimsy. They are lockable but to turn the key requires reasonable amount of effort and the lock barrels are very cheapily fitted into the covers, it would not take much for these lock barrels to break out of the covers in normal use. Apart from this they are very good and sturdy and i have no regrets buying them.
