Also known as TA Auto-extractors.

Aluminum dust caps w/ chrome-plated self-extracting cro-mo M8 crank bolts eliminate the need for a crank puller. Universally suitable for square taper crank arms with standard M22 extractor threading (such as Sugino, Miche, Andel, etc). 


🔧 The dust caps are installed in the M22 crank extractor or dust cap threads in your crankset using a pin spanner and the bolt takes a 8mm Allen wrench to both install and remove your crankset. The bolt installs the crank as it normally would, by tightening the crank arm onto the spindle. To remove the crank arms, simply turn the 8mm bolt counterclockwise. Instead of the bolt coming out of the crank, it pushes against the aluminum cap and the crank arm is pulled off the spindle. When assembling, the small washer goes between the outer bolt flange and inner dust cap.
