There's a reason why these are the Shimano apex. Outstanding, very precise and crisp shifting. The price on BTD was awesome! Have one set on a 2013 Ridley Helium and got this set for a 2018 Helium SLX frame. I recommend using these with Dura Ace rear and front derailleurs.
These replaced my previous set of Dura Ace 11 speed levers which ate the cable inside the lever and was (I thought) ruined.
The new levers work great and I hope Shimano has upgraded then so they don't eat cables any longer. We'll see.
But when new they certainly work well!!!
