The brainchild of Paul Gould, brought to life by Crundwheel. A set of adjustable spacers for flight fins. Split into sections and with oversized bolt holes, allowing adjustment and twist of the hook to better match your foot position. Add more spacers to extend further and allow more twist!

You'll need longer bolts, and the length will depend on how many spacers you fit. As a starting point, the standard flightfin bolts are 30mm, 25mm and 2x 15mm long. They are imperial, so you'll want to order M5 stainless bolts, nuts and washers to replace everything.

Curved Top and Bottom is a pair of 2 parts, one concave, one convex, extending the flight fins out by 9mm. (Note: You will need one pair per hook)

5mm Spacer is a single 5mm thick flat spacer.
