I just wanted to chime in my experiences using the Sensah Team Pro shifters which are 11 speed Shimano compatible in both carbon and alloy. The alloy version can be purchased for about $55 USD and the carbon version can be purchased under $120 USD or about $100 during the holiday sales. My initial experiences with the alloy version was fairly neutral. They worked fine, but I didn't find them better than 11 speed 105 shifters. Brake feel wasn't anything special and shift performance is decent. Though having used the carbon version, they just feel better. The braking is more responsive and easier to dial in. Also the shifting is a bit more crisp. In fact I've become so accustomed to the carbon version of these shifters, I've decided to install them both on my 2x and 1x road bikes.
Anyways, I would presume the internals would be the same with only the levers being different materials, so I'm not sure why the carbon shifters would have a more precise feel? I have no experience with the Sensah Empire shifters, but I'm guessing the tactile haptics would be similar as well. Is it possible due to the slightly higher cost, the carbon version just has better quality control?
Curious what everyone thinks?
