Following an off about 5 years ago I replaced my 10 speed 2005 Campag Centaur rear mech with a 2015 Campag Veloce rear mech. I couldn't seem to get the rear indexing set up very well so fitted Rivendell bar end shifters. They work, however, I do lose concentration momentarily as I change gear both front and back.
I've still got the original 10 speed Campag Centaur shifters and they have only covered appropriately 10000 miles, they appear almost new on the outside. The front chainrings are TA 50, 39,26 and cassette is 13/26 Veloce. Would it be worthwhile getting the shifters serviced, or is there a degree of incompatibility with cable pull and or spring tension between 2005 Centaur and2015 Veloce? Or do I continue with bar ends which after 5 years I'm not entirely satisfied with.
Appreciate advice from more knowledgeable people on this forum.
