The rundown
The main triangle is the best place on a bike to carry weight: low, centered and out of the wind. The Triangle half-frame bag tucks 4.5 liters under your top tube while leaving the down tube bottle cage usable on most frames.
A water-resistant zip opens on the drive side for tools, food and a pump, and an internal divider stops everything sliding into one heap.
What you get
- 4.5L half-frame design keeps one bottle cage free
- Water-resistant zip with storm flap
- Internal divider + key clip
- Top tube and down tube straps, no tools
- Reflective trim
