Rear Axle 148 x 12

Replacement Rear Axle.

For Hastes, purchase a 1.75mm thread pitch axle.

For Onsets, check your serial number to confirm axle version required.   Serial numbers are located on the bottom bracket shell and start in "TK".  If there are 6 numbers that follow it your bike is a 1.75mm thread pitch.  If there are 10 numbers after the "TK" your bike is a 1.50mm thread pitch.
