Rapha, nice but a bit pricey?

that argument is beneath you.
that fat banker will get enjoyment from his Di2 drivetrain, and enjoy his cycling. it really doesn't need to go any further than that, does it.

Plus, if fat bankers all stop buying high end cycling kit because they are not worthy,then there will be no more high end cycling kit, because no one else buys it in any kind of worthwhile numbers.

It's not an argument, just an observation in response to what Nurse Vacation said. The fat bankers are welcome to buy the kit and enjoy using it, I don't begrudge them. just it won't make them any faster.
