### Pros and Cons
| **Pros** | **Cons** |
|—|—|
| **Spacious Storage:** 40L is plenty of room for a full change of clothes plus a laptop and lunch. | **Bulkiness:** When fully loaded, the bike’s rear profile is significantly wider. |
| **Weight Distribution:** Double-sided design keeps the center of gravity low and balanced. | **Strap Attachment:** Depending on the rack, initial installation can take a few minutes to get tight. |
| **Durable Construction:** Built to withstand daily wear and tear and resist abrasions. | **Heel Clearance:** Riders with very large feet or short bike frames may need to adjust the position to avoid “heel strike.” |
| **Commuter Friendly:** The carrying handle makes it easy to transition from the bike rack to the office. | **Fixed Design:** These are usually joined together, meaning you can’t easily use just one side. |
