Bicycle Tool, Crank Extractor - Square Taper & ISIS/Octa Link w/magnetic attachment - Includes 14/15mm socket/8mm Hex

The ProSeries Bicycle Crank Extractor Tool is a dual-purpose crank puller designed to remove both standard square taper and splined ISIS Drive or Shimano Octalink Crank Arms. It includes a 14/15mm socket/8mm Hex.

• Dual Design - Features a removable or magnetic tip adaptor. Use the small tip for square taper spindles and remove/flip it for the wider push-rod required by hollow splined axles (ISIS and Octalink)
• Standard Threading - Fits standard M22 x 1 crank arm internal threads
• Operation - Typically operated using an 8mm hex wrench or a 14/15mm spanner depending on the specific handle or socket configuration of the tool variant

How to Use a Crank Extractor

• Remove Crank Bolt - Use an 8mm hex wrench or socket to remove the retaining bolt from the centre of the crank arm
• Retract The Tip - Ensure the inner pushing pin (the rotating tip) is threaded back out so it does not protrude past the outer threads
• Thread Into Crank Arm - Screw the o uter body of the extractor clockwise into the internal threads of the crank arm by hand until fully secure
• Extract The Arm - Turn the handle or inner bolt clockwise with a wrench to drive the inner pin against the bottom bracket spindle, pressing the crank arm off the taper
