hi, I am new here and have a (probably stupid) question. I have a Minoura RDA 850 bike trainer that I got for free from a buddy of mine. I'm trying to set up my older Schwinn Varsity road bike for training during the winter months, but I am not sure how to set it up because the directions on the Minoura website only explain how to set it up using a quick-release skewer. Anyone have experience using this kind of trainer with an older bike? Thanks in advance.
