Deore DX RD-M650 pulley replacement? 10T or 11T?

[count_zero]

Hi!

I'm trying to get my old RD-M650 to work again but need new pulleys. The original pulleys got 10T and while those are still to be found I've found 11T pulleys with sealed bearings for a lot less £££. But will these 11T pulleys work or am I restricted to 10T pulleys (does it matter att all?)?

Cheers!

Re:

You gotta stick with 10, I'm pretty sure.
