While I have been riding for years I have never used clipless pedals. I just invested in my first real "roadie" bike and need shoes and pedals. I really like old school stuff and want to wear merckx adidas shoes. Any advice on a modern pedal that works with these? The pair I found are NOS from the box, do I need to buy cleats or do they already have them? Thanks for your patience. Ex-courier, getting old, getting gears, getting roadie.
