This may be my imagination, but it seems to me it is more difficult to replace a rear wheel with the 7800 Dura Ace components than with most other components. I have not been riding and maintaining road bicycles very long, maybe 5 years. I have had mostly Shimano equipped bikes, which include 105. Ultegra, Tiagra and 9 speed Dura Ace.
I have not had a problem mounting the rear wheel until a month or so ago when I bought a used Cannondale with 7800 components. Thought it was just me. However, today my wife also bought a used Schwinn Peloton LTD with 7800 components. I replaced the tires for her with new rubber, but when I started to mount the rear wheel I again had a problem.
Is this my imagination, I am doing something wrong, or is the 7800 contrary?
