I have older Campagnolo Chorus 10-speed shifters. They are marked 'Carbon BB System'.

I am replacing my front derailleur and have a spare 10-speed Record QS front derailleur. QS stands for Quick Shift. I understand that the QS system changes the ratio that operates the derailleur.

Will an older non-QS lever work with a QS front derailleur?

In short the answer is Yes.

From the installation & maintenance manual

The new QS Ergopower controls provide for fast operation and a lower shifting force if used with the new QS front derailleurs.

The QS Ergopower controls and the QS front derailleurs can also be used with non-QS Ergopower controls and front derailleurs. However in this case please note that:

  • QS Ergopower controls with non-QS front derailleurs could require a higher force to effect shifting.
  • Non-QS Ergopower controls with QS front derailleurs will require at least two lever movements to effect shifting.

The answer given above is substantially correct but it is also worth noting that failure of lever 2 - the upshift lever on the ErgoPower - is significantly more frequent if: A non QS FD is used with a QS lever A non Campagnolo crankset is in use, even if the FD and lever "match".

As the main Campagnolo factory-appointed Warranty and Service Centre for the UK, we can assure you that the above answer is correct.
