Rear Axle Length - TC Bros Hardtail

[Yippie72]

TC Bros hard tail installed on my '72. Anyone out there know what length rear axle I will need as my stock one is too short??

Isn't Tc Bros hardtails make to fit stock wheel, spacers, etc?

stock wheel, spacers do fit but early model stock axles are too short.

According to their installation instructions '74 and older axles are too short to use with their hard tails. I found a problem with that. My '74 axle was not too short. So, from my experience, I would say that any axle '74 and newer is the length that you need. If my ciphering is right, that would be 10-3/4", shank and threads, not including the head.

The early bikes, 70-73, had 1/4 inch thick axle plates, the axle was the length needed for those axle plates. In 74 they made many changes to the frame and swing arm, 3/8 inch axle plates were one of those changes. Thus a 1/4 inch longer axle was used.
Measure the axle plates on your frame. If 1/4 inch an early axle should work. If 3/8 use a later axle.
