just an FYI, if anyone is looking for bearings for bikes, mostly wheel hub bearing which are usually sealed bearings.
When you get the bearing out there will be a number stamped on the bearing which gives the inside and ouside diameter of the bearing.
"Reliance Bearing's" based in Little Island in cork stock these, they also have offices in Limerick and in Dublin. The guy in the stores there is vey helpful and he says he sells a good few bearing the bikers so their well used to us.
Got a bunch of them yeaterday, cheaper than CRC also and easier to get as you just have to give them the number stamped on the bearng.
