I understand that the UM510 has 62.5mm bones from pin to pin. Then there is the axle that is 2mm longer than stock with the 3 grooves. but how long is that axle? I want to find out if it fits in the front hub of the proradiant.

Thanks for the help ans sorry for insisting


Oh and I forgot to ask... What part of the eaxle is longer? I mean, is the cross pit at the same position and there is more thread or is the thread the same lenght and the pin is farther away from the cvd articulation?

Look at it like this 62,5 bone with stock axles same lenght as old ultima (W5061) and the 3 groves ar 2 mm longer. Lenght on the axle is as you guessed the thread is same but the distance from the drive pin to the end where the bearing comes to an halt is longer.

The distance on my Um510 ( 3 grove axle ) is 15 from the pin to the end where the bearing stops. from the pin to the other way is 2 mm where there is no more shiny axle and then basicly the thread begins.

I belive these come swith the stock axle= shortest distance from bearing face to the crosspin for the hex
