The 40mm Screw CNC Aluminum Folding Arm Tube Joint is with thick CNC metal parts, better strength, not easy bending deformation, will not produce the phenomenon of virtual spaces after locking! The lengthened backrest solved before tightening the screws after a rebound phenomenon cannot be!

The 40mm screw folding mechanism is similar to the 30mm version but offers a larger size for heavier-duty applications. It provides enhanced stability and strength.
The Screw locking structure, to solve the carbon tube and folding seat-bit virtual phenomenon more closely and the moving shaft is changed from the copper shaft to a higher strength stainless steel shaft, which solves the phenomenon that the bending of the shaft is easy for a period of time.
