B-RAD Pump Bag

Wolf Tooth Components

This low-profile Pump Bag is named for the 12-inch pump it can carry comfortably but that’s just the beginning.

The bag is large enough for a pair of 29er tubes or lightweight jacket, wallet and even a cell phone.

The Pump Bag has four mounting grommets that mate with the B-RAD 3 or 4 base, frame water cage bosses, or top tube fuel tank bosses. It can also be strapped to most frame tubes using the included silicone-backed hook & loop straps.



  • Can be mounted directly anywhere there are bottle cage mounts.
    • For the most secure and adjustable mounting, use a B-RAD 3 or 4 base.
    • If mounting directly to frame bottle cage mounts, be sure to use protective tape where the metal grommets (holes) might rub.
  • Can be mounted to most any tube on the frame with the included silicon backed straps
  • Holds pumps up to 12 inches or 30cm long with room to spare for tubes, phones, tools, clothing and other ride essentials.
  • Note: always check for appropriate clearance under all riding conditions including under full compression on a dual suspension.



    • When mounted on the underside of downtube check clearances before riding
    • Choose 2 of 4 grommets spaced at 64 mm (they are the same pitch as bottle cage mounts)
