This is a smart trainer for indoor cycling. Purchased in 2020. Selling due to replacement. I used it 2-3 times a month with Zwift at its peak. I have used it without any problems so far. ● Smart trainer body (with sprocket) ● Box ● Instruction manual ● Accessories (adapters, spacers, etc.) ● Power cable ● Front wheel holder A Shimano sprocket (CS-R7000) is also included. There are some minor scratches and dirt from use (especially around the sprocket). Please feel free to ask if you have any questions. Thank you.
