Topeak Dynapack 2.0 4L Seatpost Bag

The unique DynaPack® 2.0 seatpost bag is the perfect solution for those who don’t want a handlebar bag or full QuickTrack® system but occasionally need more capacity than an under seat bag. Constructed of molded 600 denier for a sleek, aerodynamic profile, the DynaPack® 2.0 easily holds tools, inner tubes and other essentials with room to spare for a light rain jacket, small picnic lunch or anything else you might need. A light weight aluminum exo-frame holds the DynaPack® 2.0 securely while a quick release seatpost mount makes installation and removal a breeze.

• Smaller version of the DynaPack® without needing a separate rack
• Molded from rigid EVA foam and 600 denier polyester for a sleek, aerodynamic shape
• Divided main compartment, plus one zippered compartment
• Aluminum exo-frame features a quick release mount
• Attaches to seatposts measuring 24.5 - 34.9mm.
• 4L
