The welded PVC body, roll-top closure and anti-slip mounting system are built for road, gravel and touring use.

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.
