Got it. Funnily enough the thumb trigger on LTwoo is what caught my fancy. I have Shimano and SRAM.. And this looked different.
I really like the Sensah shift motion and ergonomics. It looks clean with just one brake/shift lever. The only thing I don't like is that the shift cable routing is a bit convoluted (same as LTwoo), you really need to pull firmly on the shift cable near the RD to make sure there's no slack (indexing will be off) and downshifting might require a bit of finger reach if you're in the drops (requires double clicks). On the plus side I feel the shifting is smoother under load when climbing compared to Shimano, the shift clicks actually sound cool and definitely the lower price. I don't race, so the nuances of shifting might be an issue, but I've never had any problems on fast group rides.
Also at this point, I think Sensah as ironed out a lot of their early production issues. I consider them one of the more mature Chinese brands at this point like Senicx, Onirii, etc. State Bicycles in the US use their components and they're starting to pop as an OEM on some entry level bike builds. Even though LTwoo has been first to bat with hydraulic and now electronic, I don't consider them a mature brand yet with solid components.
