When transporting our tandem with a rear rack, I take off the wheels, so that it doesn't stick out past the car. Unfortunately that leaves the chain free to rub against the chainstay.
I'm looking for something to hold the chain in place with the wheel off. I've found the Pro Gold hub master, but not in a tandem size.
There's also the Bike Medicine chain holder.
However I have two issues with the Bike Medicine Chain holder, both relating to the fact it doesn't go across the dropouts: 1) it won't provide any support to the frame in an airline case, which the Hub master would, and 2) it appears the chain could jump off fairly easily and you're back to square one.
Anybody know where to get the Hub master or similar device for a 145 dropout?
Also anyone using the Bike Medicine chain holder?
