Thank you for viewing! This is a modification manual for LIGHTNING ASCENT. It's a manual for replacing the broken resin parts with wakan belt. You'll need these tools: The manual explains the tools, materials, and all the processing steps with actual work images. The tightening is very good because it is based on the belt structure of crampons. I have sold over 20 of these so far. Based on this experience, I have created this illustrated manual, which includes the belt lengths for each part, the necessary tools and materials, and the work procedures. You might want to get the manual and try improving it. The manual will be sent as a printed copy. The printer's performance isn't great, so there may be some streaks. However, it is practical as a manual.
