How to mount the Hardwin QFS‑01 attachment system
Rotate the plastic bushings clockwise or counterclockwise until they match the width of the saddle frame.
Secure the counter-slider to the saddle by tightening the central screw with a 4 mm Allen key.
Insert the bag slider into the counter-slider until the bag shell rests against the seatpost.
Note: Once the recess of the shell is properly engaged with the seatpost, do not push any further.
Lengthen or shorten the micrometric tie rod as needed by rotating it in either direction, then flip the locking lever forward before fastening the strap around the seatpost.
Wrap the strap around the seatpost. Fasten the strap using one of the five available slots. For standard seatposts, the second or third slot is usually used.
Close the locking lever. If the tension on the strap is too tight or too low, return to step 3 and turn the micrometric tie rod one turn or more until the optimal tension is achieved.
