Step 2 Other Required Items - Aluminum duct

Check your local hardware store for sheets of HVAC aluminum ducting. My local store was out so I went to Home Despot. They had several shapes and sizes. The big sheet was 7 bucks but I managed to cut two pieces out of a smalled pre-bent sheet for under 4 bucks. If you measure your bike frame first and bring the stencil you cut out you can make sure you get the right size.
