  • 5L – RK19512B: 41 x 15 x 11 cm, approximately 440 g, black.
  • 10L – RK19511B/RK19511GN: 47 x 19 x 16 cm, approximately 614 g, black or olive; includes one 145 cm auxiliary strap.
  • 13L – RK19513B: 58 x 20 x 16 cm, approximately 802 g, black; includes one 145 cm auxiliary strap and an air-release valve.
  • Saddle Bag Stabilizer – SK500BB: stabilizer accessory only, with no bag or storage capacity included.

Built for stable bikepacking storage

  • High-frequency welded PVC main bag with a roll-top opening.
  • Lockable retainer and anti-slip contact panels help reduce movement.
  • External webbing carries light items such as a jacket or compact pump.
  • Reflective branding and taillight attachment points improve low-light visibility.

Fit and safety

Measure the available saddle-rail length, exposed seatpost and tire clearance before ordering. Allow for tire movement and suspension compression, and never let the loaded bag contact the tire. Secure every strap away from brakes and moving parts and recheck tension during the ride.
