Description

The Rhinowalk RK404 4L and RK406 6L waterproof bicycle fork bags add quick-release storage to compatible rigid or suspension forks. The included Quick-Lock hardware supports band-clamp installation on 9–20 cm fork or tube circumferences, while two M5 holes provide another mounting route for compatible eyelet-equipped forks.

Choose the correct option

  • 4L bag: RK404, 18 x 9 x 29 cm.
  • 6L bag: RK406, 20.5 x 10 x 31 cm.
  • Adapter: RP4001B replacement mounting adapter kit only. It does not include a bag.

Every 4L or 6L bag variant already includes its mounting adapter and installation hardware; a separate adapter is only needed as a replacement or for an additional bicycle.

Fast removal, practical carrying

  • Quick-Lock interface lets the bag release from the bicycle without undoing every mounting strap.
  • Roll-top construction meets the IP64 standard when correctly rolled and secured.
  • Internal pockets organize small tools and daily essentials.
  • Included shoulder strap converts the bag for carrying away from the bike.
  • Reflective details improve visibility in low light.

Materials and weights

Black bags use PVC-coated 500D polyester and weigh approximately 510 g (4L) or 570 g (6L). Orange, blue and olive bags use TPU-coated 840D nylon and weigh approximately 480 g (4L) or 550 g (6L).

Fit and safety check

For band-clamp installation, measure the fork or tube circumference: the confirmed range is 9–20 cm. For eyelet installation, confirm the fork accepts the bracket's two M5 screw holes. After mounting, compress the suspension and turn the steering fully to verify clearance from the tire, spokes, brake rotor, cables and frame before riding.
