Gearing on a dedicated trainer bike
I'm considering picking up an inexpensive bike to leave on the trainer. I currently have an 11-speed cassette on the trainer because my TCR currently does double duty as an indoor and outdoor bike.
What I'm wondering is whether it would be worth it to upgrade the cheap bike drivetrain to 11-speed or just deal with 8- or 9-speed, depending on whether I get a bike with Claris or Sora. For those of you who have dedicated trainer bikes: is the gearing the same as your outdoor bike(s)? If not, how much does it bother you on the trainer to have bigger gaps between sprockets than what you're used to outdoors?
