Campag 2011 power torque

Which is what it comes down to - I just want stuff that works consistently.. and when it does wear out I don't need a personal loan to replace like for like. Currently I need to replace my Record 10 speed rear mech - and despite the fact that it was replaced by a 11 speed component some time ago, the old part is still more expensive than the new one. Not to mention that at £250, it's £120 more expensive than a Dura Ace mech -which is just fucking bonkers

Conversely, Super Record Ergo levers are available for around £250, whilst Dura Ace STIs are £100 more, so it works both ways.
