Great product for the price, with a few minor issues. First of all (unlike other similar Yakima mounts), there is no way of locking the rear wheel tray to the crossbar. As a result, only ONE sks lock core is needed... Not two as indicated in the user manual. (I confirmed all this with Yakima after buying 2 forkchops and a 4 pack of lock cores). Yakima customer service was great, refunded the 2 lock cores and noted the lock for the rear tray as a product recommendation.
