It is an ultra-thin conversion collar with a wall thickness of only 0.17 mm that allows the use of general-purpose inch spurs (inner diameter φ9.525 mm) for φ6 mm shaft vehicles such as M300GT and M500GT.
By using this, it becomes possible to select a spur gear from a rich lineup, and the range of gear ratio settings is greatly expanded than before.

[What is included in the product]
● Conversion color x 1 ● 6.35 x 9.525 ball bearing x 1 (for spur gear)

Be careful when handling because it is an ultra-thin processed product!
●As this is a product for advanced users, some tricks are required for installation. Do not use if you are a beginner as there is a risk of damage.
● If you squeeze it too hard, it may deform and become unusable.
●Please note that we cannot respond to complaints regarding deformation that occurred during installation.
●In the case of the optional carbon shaft, the frictional resistance at the time of installation will be greater than with the steel shaft, so please be extra careful when installing.
