Hey Taras, just FYI (and to other iO owners), it looks like the bearings are actually 61901, 24x12x6mm. The one's in this wheel are NMB r2412zz (though only one metal shield is fitted) which I cross referenced to the SKF number.

Also, for Mavic newbies (like me...) the axle is a slight interference fit, and needs to be lightly tapped out (screwdriver handle works). But be careful, the axle is aluminum and has EXTREMELY fine threads that look super easy to damage! So take care when removing/installing.
