A completely unexpected (and welcome) attribute of the Pletchser double leg kickstand I got for my second to last tandem buy was that the legs do not keep the crank from turning when deployed. More than that, they are made to be cut to length but if left full length they raise the rear wheel (26") 3" to 4" off the ground. A lot of bike wrenching requires running the RD through the gears after adjustment. Even brake work requires spinning up the wheel to see if there is any rub or grab. I destroyed the clamp of a (cheap) workstand by putting a tandem in it. Now both my workhorse tandems have their own built in workstands. FWIW.
