Campagnolo Record 2x or 3×10 speed bar-end shifters FREE SHIP

They are designed for a 2×10 or 3×10 set-up. Of course the one for the rear is longer than the one for the front. You can tighten the shifter with the d-ring so it matches the spring tension of the front derailleur- resulting in the shifter holding the derailleur exactly where you set it.
