I have a Saris SuperClamp EX 4-Bike that I use all the time to carry bikes around. It’s even on the car right now :). As cool as it is, there are times when something like the new Saris MHS could be a step up in capability, if they do interesting things with the modularity of the system. In its current form, it still might be better because it looks like there’s a bit more space between the bikes (which is an issue with the EX-4 when transporting fat bikes). That said, until they develop the platform, there isn’t anything compelling enough for me to upgrade my current setup (especially considering the $1,300+$350 price tag to get to where I am now). But that could change…
