"I will admit to not riding the Di2 bike every day and shifting 100+ times on every ride. Its one of many bikes in the rotation and I live where it is flat, so no shifting needed. But charging once in the off season will easily allow you to ride all year long with no charging."

Just curious. If no shifting is needed where you ride then why buy an expensive multi-gear system?

Cheers


I said no shifting. But I do shift a few times on rides. There are a few gradual inclines around me that need me to move up or down one or two cogs. And sometimes there are tailwinds or headwinds which require me to move up or down one cog even on the flat. But your question could also be Why buy an expensive racing bike if you are NOT a Tour de France rider? Or Why buy a 4x4 pick up truck if you live in the south and only drive to and from the grocery store? Or Why buy a heavy duty steel bike when a lighter aluminum or carbon bike is available?
