Are the PD-R540 compatibale on my indoor spinning bike (BodyCraft SPX) ? I have Shimano PD-105 on my road bike, so my shoes with these clips would work.
I can't say, for sure, whether they'll work, but the best way to check would be to take a pedal off your road bike and see if it will thread onto the crank on your spinning bike. A quick Google search did find several people who put standard-threaded pedals onto their Bodycraft bike, but you might want to check to be sure.
