main shaft bearing sizes?

[LipolyGone]

does anyone know if the crank shaft big and small bearings on the tt 53 are the same as on the os 50?
model fixings isn't showing them for the tt 53 clearly on my phone for some reason

Rear bearing is defo the same.

Front bearing is probably the same. The OS50 has the same front bearing as the TT50, so there is a good chance that the TT53 is also the same.
