Which Groupset?

Is it though? The same people would buy a £5k OTP frame, or Zipps or whatever anyway and at least Di2 gives you basically fit and forget gear changing compared to cable systems. This would save the 'city wankers' from poor shifts due to lack of tune ups.

I was talking about performance gains vs cost - there's no accounting what city cnuts will spend on bikes though... blerg.. boring.
