Have 2 of these carriers bought for 2 different types of bikes and was very positively surprised by the variability of the carrier, especially at this price. However, 2 left hands (as one of the reviewers here) should generally not have, when dealing with technology! One of the vehicles I had even with a grinder / Flex make them fit, so it does not collide with a disc caliper mount to the frame. But it may now not be considered all exotic frame structures / geometries in the design of a universal accessory part! I guess that the carrier which are at all be equipped with a solid support with 90% of all wheels (ie no Fullys) fits. A deduction of points there for the workmanship of the wearer. The struts are still some very imprecise (wrong) are welded together.
