Apidura’s Frame Packs are one of the most convenient bags you can put on your bike. They give you on-the-go access to gear in a position that keeps the weight of the bike somewhat balanced. Put your heavy stuff in here when bikepacking with a complete set of bags, or a jacket, tools and food for day rides. The Compact Frame Packs are best suited to more traditional road and touring bike geometries.
The Compact Packs are typically best suited to more traditional road and touring geometries. If your bike doesn’t have tons of standover clearance and is pretty square (equal seat tube and top tube lengths) these are likely to be the best fit. The safest bet is to grab a tape measure and consult this sheet. Small, Medium and Large carry 3L, 4.5L and 5.3L respectively.
Three velcro straps attach these bags to your top tube, then 3 or 4 locking cam straps tighten them securely in place on the head tube, down tube and seat tube.
