What about Honda Grom tires (12mm center hub)?Updated 2 years ago

We have tested a 12mm spindle but managed to bend it. It is challenging because the center spindle takes most of the forces when operating the ratchet system, and the spindle strength is critical there. Weve heard some customers have had custom-made spindles machined for them, but we are not commercializing one, as we would need to give a warranty on this product. Please see a video here made by one of our customers showing a Grom tire change with their own custom-made adapters and spindle.
