	Disassembling the Mark IV is fairly easy, although you'll likely want circlip pliers to get some retainer clips off the wheelpost. Other than that you'll be good with a flathead screwdriver to get the lever screw off, and a small (~~PH4~~-ish) flathead for removing a friction roller and maybe helping with getting springs off / back on.
