Our 12" Top Tube Bag is the most popular of the bunch. It strikes a nice balance between speed and distance. The bags tapers from 2.75" wide down to 1.75" near the seat tube. On the outside non-drive side, there is a stretch pocket for trash. We designed some stabilizers out of TPU that allow the bag to be run without any steer tube stabilizer. The front stabilizer has an insert that changes the radius of the contact point. We have had quite a few prototypes made and sent out and haven't had any issues with the bags rotating. We left the internal slots for plastic easy to access so you can slide longer items in and organize slightly.
Note:
- We do not recommend putting anything valuable or heavy in the external stretch pocket. It was designed with trash in mind, and it works well for that, but does not hold heavier items well.
