Good jockey wheels for M900 derailleur

I bought the roller boiiiis, but then my frame turned out to be cracked so they are doing nada.

Posh ceramic ones?


In the M900 mech the tension pully (original) seems to be in the guide pully position, it should be at the bottom.

Well 10,- for shit ones or 25,- for relatively good ones.
The one on the bottom cracked, the "new" one is just a placeholder as the bike isn't ridable atm.
