The Yakima Hold-Up Plus2 Add-On isn't a bike rack, but it does attach to your Yakima HoldUp 2 rack to turn it from a two-bike carrier to a four-bike hauler that works for the whole family (or your DH, enduro, XC, and dirt-jumping bikes). The Add-On bolts securely to your HoldUp2 with a straight bolt and spring pin, and it has the same StrongArm technology as the original rack, so your bikes will be safe and secure when the winds whip and the road gets bumpy. Rock-solid ratchet straps lock down your rear wheels and large ratchet arms lock down the front wheels, and there's even a built-in bottle opener to help with your post-ride libations. The Hold-Up Plus2 Add-On can carry up to 200 pounds, so even the heaviest bikes will fit without a problem, and fits almost any bike, from roadies to carbon 29ers, so you can bring the whole fleet.
