CXWXC Bicycle Frame Bag with Coated Fabric, Protected Zipper and Adjustable Strap Mounting, Multiple Storage Sizes for Road and Mountain Bike Riding

Frame-mounted storage in four sizes

These black CXWXC bicycle frame bags attach below the top tube using repositionable hook-and-loop straps. Choose from the offered 1.8 L, 2.5 L, 3 L and 4 L versions. They have different profiles and dimensions; compare the actual option image with the space inside your bicycle frame, bottle-cage position and cable routing before selecting.

Coated fabric and rain protection

The supplier identifies nylon with a TPU coating for the CX-B310, CX-B311 and CX-B312 versions. The detail photographs show coated surfaces, sealed construction and a protected zipper arrangement intended for wet riding conditions. Close zippers fully before riding. No submersion rating is stated or promised.

Strap installation and shaped storage

Multiple hook-and-loop fastening positions allow adjustment of the strap locations around suitable frame tubes. The shaped body supports storage below the top tube. Check that the bag and straps do not interfere with cables, steering, pedals or other moving parts, and compare clearance with your own frame.

Storage layout depends on the selected bag

The source shows different zipper access and internal layouts across the range. The CX-B310 demonstration includes internal divided sections. The larger CX-B310 and CX-B311 photographs show room for a 750 ml bottle as a size demonstration. That bottle-fit demonstration does not apply to every bag, and no bottle, tool or other contents are included.

Capacity, reference length and product weight

CX-B310 is listed at 4 L, approximately 44 cm reference length and 310 g. CX-B311 is 3 L, approximately 37 cm and 207 g. CX-B312 is 1.8 L, approximately 42.5 cm and 194 g. CX-B313 is 2.5 L, approximately 28.5 cm and 200 g net weight as confirmed for this option. Refer to the option diagrams for the full shape and dimensions; a longer bag is not necessarily taller or larger in capacity.

Included bag and option selection

One CXWXC frame bag in the selected capacity and profile is supplied with its fastening straps. Bicycles, bottles, pumps, tools and demonstration contents are not included. This listing includes CX-B310, CX-B311, CX-B312 and CX-B313 only.
