Stationary stands are notoriously hard on nice bikes,

stationary trainer that can be set up to resemble your real bike fit will be OK.

Theres these http://www.lemondfitness.com/product...mond-revmaster

there are some oodles cheaper of the style. use your 9/16" pedals and seat.

adjust seat angle and reach and height.
Sharing? a numbered scale will let 2 different people adjust 1 trainer to suit them ..



or of course the beater on the stand with rear wheel clamped in place will do,

get the set up adequate, and then the wear and tear on the real bike wont happen.
