I recently bought an indoor trainer for my road bike that came with its own rear skewer to use with the trainer. I am not the best at bike maintenance, so I am unsure how to proceed. On my back tire I removed the two bolts that let the rear tire come off the dropouts, but am unsure how to remove/install the new skewer. It doesnt look like there is a skewer on there at all, and do not know what to do next. I would also be interested in purchasing a separate tire for use on the trainer if that is an easier option. If I purchase a new tire, could someone give me a model name or something so I know what I need to use the trainer correctly? Thank for all your help!
