Challenge Bead Seating Tool - made of lightweight, durable nylon plastic. Strong and indestructable, this heavy-duty tool uses much more leverage than the weaker, more brittle tire lever. It also never intrudes with the inner tube, so you will never puncture it! And finally the nylon material avoids undesired scratches to the rim wall of your beautiful wheels during use. It can be used for tires up to 46mm...

• Use: on Clincher tyres
