Leave it to the Germans to make a great, easy to use, sturdy, and quality product. Came with instructions in like 10 languages. Talk about thorough. I have a 29er MTB and this holds it perfectly. Took about 5 minutes to mount it to the roof rack and it takes me another 5 to mount/dismount my bike by myself. I decided to stick with the MB OEM roof rack and bike rack because there were way too many mixed reviews with other branded products. I'm glad I did. And the price was comparable too. I will definitely be purchasing one or two more for when I want to go riding with friends and that way we can carpool.
