Difficult, Slow-fire shifter
I just replaced my 3x8 front derailleur with a Shimano Claris 2403 8-speed triple. I also have a trigger shifter, Shimano Acera shifter. Everything works fine but to get it to shift into a higher gear it takes an extraordinary amount of thumb power both in terms of strength and distance to push the trigger shifter. However, once it clicks it shifts into the higher gear. Does anyoneknow what could be causing this problem? Were these shifters built with a super strong spring or poor leverage that it would require such power? Did I mess something up?
