So I thought I did this finally for this upcoming winter season.
I bought a separate wheel to use specifically on the trainer with a Shimano cassette so all I have to do is swap out the rear wheel and I can change quickly between road and indoor. However my plan did not work because I did this yesterday and I my rear mech was not shifting properly after switching out my trainer wheel. The problems I have after the change are missing gears, and that issue when your in the small chainring and big sprocket, and when you shift out of the big sprocket it hovers on the top or something like an old man testing the bath temperature.
The setup:
Outdoor wheels are Mavic's with an Ultegra 12/25 cassette (ultegra DI2 drivetrain)
Indoor trainer wheel is a Shimano RS11 (with 10 speed spacer) and a 105 12/25 cassette.
My initial thoughts are that (1) the reason I get fine adjustment problems is because the Mavic and Shimano wheels align the cassette slightly differently, (2) my drivetrain needs to be serviced by professional, or (3) there is a tiny difference between the 105 and Ultegra cassette and its messing up the alignment of my rear mech.
