Weight weenie question - weight difference between Shimano R8020 and R7020 Groupset
Quick question, hopefully easy. Is there somewhere that total group set weight is published and compared (versus adding up individual components, hoses, rotors, etc)? Wondering how much weight is truly saved by going with Shimano R8000 series disc group over R7000 disc. I'm switching from older Ultegra 6700 10 speed bike, so I'm thinking R7000 will already be a significant improvement in performance for me. Only reason for me to pay the extra for Ultegra would be purely aesthetic or weight savings. Thanks!
