Installed 10” Alpha wheels on my pro.
Alpha wheels were $100
Offset axle was $160 from tricked toys.
Found it interesting that I didn’t lose any footprint. The way the offset axle is made it moves the axle forward and up.
Should have less rolling resistance with the bigger wheels. I initially thought it would help it rollover easier. The offset axle is for a 9” wheel, I used a 10” wheel to give it a little bit more height in the centre similar to a Alpha rail. Will have to wait for snow to feel if it helped with handling.
