I'm 6'2 myself and for my 2019 I rode the XL and with my 2023 I went with the S6. The reach was long comparing the two, I ended up changing the stem to a 35mm from the stock 55mm and that made it very comfortable, and I really love the longer wheelbase of the S6 along with more room to move...
Not sure this would work as the Magura has the bolt pointing down and the looks like it needs to be putting towards the rider to work. This is the clamp you mentioned?
I followed the app and it listed 118 for when I input High setting, it was until a day after that I thought about running it in low and the app then showed 120
Only catch on the chain length is if you want to run the 36T and in the low setting it shows you need 120 length vs the 118 length for the 36T in the High setting. So I cut mine to 118 and if I want to run low I have to switch to the 34T chainring.
Just and FYI, I have the beta of OS 10 installed on my Ultra and was excited to get it hooked up to my levo. Levo only supports Ant+ for showing power, cadence, and speed. The apple watch does not have Ant+ support only Bluetooth so there is no ability to connect it.
I have my current SL that came with Fox dropper and shim and I will tell you it's not worth the weight savings. My buddy has a Levo Expert with a shim from the factory as well and they both develop creaking from the shim and require frequent cleaning to keep them silent.
