Can i use this bearing

[andsaw]

I have a 41.8 x 30.2 x 6.5 45/45 headset bearing, i have found a near perfect size but not sure if its ok, the one in question is under part number MH-P08 and is identical apart from the inside diameter which is 30.15 will this make a difference and if so what would happen if anything.

To put that difference in perspective, I've just measured my Tesco value aluminium foil and it is 0.01mm thick.

Assuming the steerer is 1.25", that is 31.75mm, so I think it should fit.

It will be ok.

The angle isn't affected so all that will happen is that the bearing will sit ever so slightly higher on the crown race (or the compression ring at the top) but still work perfectly.
