How do you guys transport multiple bikes including a TT bike with rear disc? For a single bike I've always just put it in the back seat with the front wheel in the trunk, but adding a second bike poses a problem. I'm considering a tray-style hitch-mount rack to put on my wife's SUV for traveling to stage races, but some of the more popular options (Thule T2 Pro, Kuat NV 2.0) don't work with a disc wheel since they are designed to run a strap through the rim of the rear wheel.
Reading through some discussions on the topic at slowtwitch, some recommend racks that use an arm over broth the front and rear wheels, such as 1up USA or Inno. Others say it's too risky with the disc wheel, put a training wheel on for transport. I guess my question is how much wind is the wheel going to catch at highway speeds if it's mostly sheltered by the SUV? I guess it's worth mentioning my disc is HED Jet+, so we're talking fairing/cover, not solid CF.
The training wheel seems like the safe/obvious option, but would be a PITA: having to bring an extra wheel in addition to race spares for the road bike, plus swapping the wheel and handling the chain, etc. But the biggest hassle is that the Jet+ barely fits my TT frame even with 23mm tires; the wheel has to be perfectly aligned in the horizontal drop-outs to avoid tire-rub when getting out of the saddle, and getting it right can take a bit of trial and error. I'd rather not have to be messing with that right before a TT is about to start if I can avoid it.
get the 1up. i've had it for 6+ years. works with every bike i've ever thrown on it......and depth road wheel (including disc), lefty forks, my kid's 20" then 24" and now 24plus bike, and my wife's new bike with 3.0 tires.
(3.0 turns out to be the maximum width in 'stock' configuration, but with a spacer kit you can fit up to 5" tires -- and, yes, i know some folks that actually have bikes with 5" tires that weigh more than their frame.)
love the modular aspect.
everyone who loads a bike onto my rack comments on how great it is, and that includes owner of pretty much every other rack.
highly recommended.
