      First new cranks

      Got for christmas and self installed on my 2018 dk octane XXL and they were really easy to install and so far they are holding up just fine, they did come loose on me once because I had a spacer that kept the shaft from getting enough contact with the crank so it dug into the inside splined hole in the crank but they still work just fine. On a very problematic bike they are holding up pretty well

      Quality

      As always box hits it out of the park. Best parts on the market. Fast shipping and great customer service. There is a reason my whole team rides nothing but box components.
