Flap is a tape made in special PVC that in traditional spoked wheels protects the inner tube from chafing and lacerations to the head of the nipples. The same Flap, thanks to the particular characteristics of elasticity and resistance to drilling, is also used in the wheels with tubeless tires, since it adheres perfectly to the hoop without allowing air leakage. To facilitate the mounting on the rim, allow a precise positioning in the channel and correct any imperfections of the same, you may want to move a stroke of normal liquid latex sealant that is normally used in the assembly of tires and preparation of tubeless rims.
Available for rims 16 (25mm wide) - 18 (30mm wide) - 19 (30mm wide) - 21 (20mm wide)
