Well, just awnser the question. Would you take Holzfeller crank arms (note: not the BB, just the holts.) over hussefelts if you will not be able to upgrade. I can feel the flex on my stinky and dont want to be able to feel it on my Demo and not be able to change it. So is it worth 100$? (or if anyone has any slightly used ones theyd be willing to sell me PM me with a price cheaper than that...)
