It all depends on how mechanically inclined you are. Its not a walk in the park. You have to split the case and press the crank out. Once you get it out you will have to ship it to FST. If you do this be prepared for the bike to sit for a while cause it does take them a little bit to get the crank back to you. I have no idea what a shop would charge for this but I dont think it would be on the cheap side.
