          alright crank, see how long the finish lasts

          looks nice, works well, I went for 165mm even though I'm 6'2 , cos my ebike has 165mm cranks and I like the riding position, feet more side by side when pedals level... ground clearance difference between 175mm cranks on my other bike is hard to define , cos rocks and roots vary in height, nice bluey tinge to it, hope it doesn't were off too quick , I went for the middle Q factor one, cos that's what's recommended for boost axles, but I could have gone for the shorter axle m7100 , difference being a few mm in axle length, meant I had to run the two spacers on the crank that came in the box, but I gives me more clearance on the chain stays , which is good , cos my right shoe sometimes catches my chain stay protector, so every little helps ... you will need yet another special tool to fit the chainring though... annoying.
