Park Tool is the most well known and trusted manufacturer of cycle tools in the world. Their tools have been made in Minnesota USA since 1963 with one aim: to build the best tools possible.
To remove your cranks simply remove the dust cap (if any) then undo the crank bolt. If you have ISIS cranks attach the larger diameter tip to the extractor, or for square taper cranks use the smaller diameter tip. Next screw the threaded outer barrel of the Crank Extractor into the matching thread on the crank. Keep turning it until it stops. Then screw in the inner barrel of the extractor. As you turn the inner barrel the foot pushes on the end of the axle and pulls the crank off. You'll need to use an adjustable wrench or adjustable spanner for this part of the crank removal.
