The original Cargo Switchback came in a variety of sizes throughout the 90s and early 00s. This bag will not have a product code on the tag.
The wheel repair has been adjusted to fit best with a 69mm wheel and not a 70mm wheel. Most of the bags no longer have a riveted wheel, so cutting the axel is unnecessary.
This kit is designed to remove the current clip, slide the wheel off, and use a new clip. If your bag has the axel riveted on, you will also need to purchase a replacement axle.
