I had a Yakima Hold-Up. Had a Size L HT MTB I used in it no problem. When I got a FS Size XL MTB I had issues with it fitting properly. It would rock when secured and actually had a few scares driving down the road. I think it was the longer wheelbase of the bike. I want to get a new Yakima platform rack. Looking at the Hold-UP EVO and Dr Tray. Anyone have any issues with Size XL MTBs on these racks? Thanks
