The Kohla race tips are a full-featured combo of bungees, rivets, stoppers, metal crimps, and plastic end caps. Cut and fold some skin over the bungees. Punch or drill some holes and hammer the rivets in place. Adjust the stoppers for you desired tip offset, and crimp them in place. Finally, place the plastic end caps to give yourself enough to grab and trim off the excess bungee. Voila! Race skin. If that didn’t make sense to you, no worries, the Kohla kits come with instructions that explain it even better. They also come with PVC reinforcements to prevent the bungee from ripping through the skin (or to fix one if it did already).
Sold as a set with enough material to complete 2 individual skins.
