Review on 🚴 Enhance Your Cycling Performance with SHIMANO SW-R600 Di2 Climber Satellite Shifter by Antonio Bly

I give this derailleur 5 stars because the company refunded my money after I found it didn't fit my bike. Make sure you check your control input connected to your switch to make sure you have an input available for that climbing switch. I have a 2016 S-Works Tarmac Di2 drive (Dura Ace switch) and checked YouTube to see how this switch would fit. Seemed pretty simple, just plug it into a control box on one of the existing switches. I then quickly checked my control box by pulling on the rubber shifter/brake lever cover and found that there was an available input as detailed in the YouTube tutorial. Unfortunately, when the climbing switch arrived and I tried to install it, I found that the second entry was wrong and had no hole to connect the wire from the climbing switch. Totally my fault for not checking carefully enough before buying, but they refunded me as it didn't work. The product description only lists the previous Di2 model as not compatible, but doesn't specify that you need to make sure you have an AUX input to connect it (from what I've read they all had two inputs) . You probably think it will be obvious, which it probably should be :)
