Typically, most stationary trainers clamp onto the rear wheel - by way of the quick-release "end knobs"
But...... I called two manufactures and they could not answer the following question (both cycleops and balckburn)
Will a bolt on rear wheel, where there is a nut and axle (like on a fixie or single) fit into the stationary trainer clamp. The two arms that clamp on. Will those cup arms fit over the nut of a fixed or single speed?
Like the picture below
Thank you for time and help
