To play nice with the Loop bars, we tweaked the design of the Sweetroll for this spring, adding attachment points to mount the bag to 4 points on the bars. This gives bomber stability and separates the bag entirely from the frame / fork area.

Use the Jones kit to add spacer blocks and straps to the added mount points. You’ll notice the bag sits farther forward, access to the front pocket is better and there is nothing attached to the rest of the bike. You need to remove the lower steerer tube strap from the Sweetroll when doing this.
