Zacro Training-Wheel Axle Extension Kit — 3/8-26 Thread
A thread-specific extension for training-wheel mounts.
This Zacro kit provides axle extensions for suitable single-speed children’s bicycles whose rear axle is too short for the intended training-wheel mounting arrangement.
Kit contents
- Two axle extension bolts
- Two metal support pieces
Check the exact thread
The supplier specifies a 3/8-26 bicycle axle thread. Confirm the rear axle’s thread, available engagement and mounting arrangement before ordering. Wheel diameter alone does not establish compatibility, and this is not a universal fit for every Huffy or children’s bicycle.
Fitting
Have a competent bicycle repairer check the axle and training-wheel fit, and follow the bicycle and training-wheel manufacturers’ instructions. The bicycle and training wheels shown for illustration are not included.
