no but really, your shifter has a collar on it with an allen screw going through either side, tighten that up and it won't move

"People always ask me, 'is it worth it, getting hurt that much?' and the answer is yes, I would do it all over again, have six more season ending injuries in the next 10 years to keep doing what we get to do, there's nothing better than sliding down snow and flying through the air"
--RIP Shane, you will be missed
