Ever have a 3-piece crank arm stuck? Maybe it has a little lip catching on the axle. We know the 3-piece is 'old' tech for BMX racing, but it is still the standard in freestyle. This is a trick we learned from the old school guys and is one that mechanics tend to forget.

1. Remove the pinch bolt

2. Find some thick & big fender washers

3. Place the washers in the pinch bolt gap.

4. Insert the pinch bolt and tighten it until the arm is loose enough to remove.
