Product name: bicycle a disassembling tool/tools/tooth sprocket wheel/bike/crank/crank tool Remover

for sprocket wheel and crank-
shaft type. Send an Afterburner handle (thin, and even some of the time to prevent damage). Mind riders use carefully!

There are two parts, black is the "wig", white is the "top bar"!

Use two, comfortably coiled handle the tooth!

Head 16MM don't have to worry about the top rod is not long enough, and fit a variety of shaft fixed!Hood is screwed into the crank, keep in mind that the headgear to the twist in the end, do not there is no twist in the end, use a push rod to the top Oh!!

    In this case, really easy to crank teeth made of aluminum to pull bad!!! Oh, I am not responsible for broken!!

     Hand tighten, twist when not moving with 16MM wrench leveraging, twist in the end! Head gear tooth pattern of maximum difficulty, when not in use top Rod top crank to pull the crank tooth marks bad!   

(Performance because aluminum is quite soft, so accidentally aluminum teeth lines drawn this bad)

Be sure to remember, I also had a difficult time!!!Then the rod is screwed into the wig, you can use the 16MM wrench leveraging! Without a lot of effort to remove sprocket wheel and crank!

    Without this tool, my mountain bike sprocket wheel is alive by the mechanic spent nearly an hour knocked waste! Now think of it a little bit a pity!
