DESCRIPTION

This is our version of a full length top tube without going the custom route. The bag tapers from 2.75" at the head tube down to 1.75" nearest the seat tube. There is an internal velcro divider halfway down to help keep organized. Internally there are 2 stretchy drop pockets on either side of the front half of the bag. 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 15 or so prototypes made and sent out and haven't had any issues with the bags rotating. All 5 colors offered are the best materials available. Check out our "materials" page to read more about the specs of the fabric. 

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. 
  • If you are on a small frame, your dropper seatpost may contact the back of the bag and deform the plastic in it. The 12" length may serve you better.

The San Util Fault Line Top Tube Bags are large, but not necessarily extra large. I tested the largest of its three sizes, and the rearmost tip was still in front of my saddle and in reach. It’s like a glove compartment with its own little trunk separated by a Velcro partition. It’s low and sleek, but it’s still big and long. I was worried it wouldn’t be stable. A truly full-length bag can cling to both the seat tube and steerer tube for support. The Fault Line does neither. It has different tricks up its sleeve.
