Weatherproof DynaWedge, Strap Mount

The Topeak Weatherproof DynaWedge is a sleek, aerodynamic under-saddle bag built for riders who want fast access to essentials with full weather protection. Its streamlined profile reduces drag, while the water-repellent 210D/420D nylon shell and coated zipper shield contents from rain and road spray. The unique center opening makes gear retrieval quick, and secure hook-and-loop straps keep the bag stable on rough terrain. Available in standard and large sizes for flexible storage. Aerodynamic, Low-Drag Shape: Slim, streamlined design fits neatly under the saddle to reduce drag and maintain a clean aesthetic. Full Weather Protection: Constructed from 210D/420D nylon with PU coating and a water-repellent zipper to keep contents dry. Quick Center Access: Unique center opening design allows fast, easy access to tubes, tools, and essentials. Secure Strap Mounting: Hook-and-loop straps create a tight, rattle-free fit on seatposts from ø25.4–31.8 mm. Two Size Options: Choose standard (0.35 L / 21 ci) or large (0.6 L / 36 ci) to match your storage needs. Manufacturer Sku: TC2293B Todson Sku: 63002293
