If you have a 2-inch receiver hitch, I recommend either Hollywood racks or the Swagman xc racks. I have had both and personally prefer the Swagman for convenience because it has adjustable loops that you rest the tires of your bike in as opposed to standard protruding bars that you rest the top tube on. This allows the rack to be usable with any style of frame, whereas a standard rack is incompatable with monotube frames like the the Trek Y-26. On the other hand, the Swagman doesn't offer any convenient way of locking your bike to the rack...which is a feature I really like on the Hollywood racks. Anyway, either of these racks are very nice options.
