MTB helmets are evoluting in almost daily bases....trial helmets are the same over the years....maybe is time to change....

Very small motor but it was underpowered comparing with others 4t

Outer races go out easily with a long chisel.

This practice (removing bearing with a drift off center) move bearing crocked what on long therm enlarge hub diameter. Jitsie make a wheel bearing extractor that solve this issue and is able to remove Rear wheel bearing since spacer id is smaller than bearing id.
