Hi all

I hope you can help...

My bottom bracket (sealed cartridge) is in dire need of replacing on my 2004 Tyax Super bike. I have found plenty of info on which bracket was used on the 2007 model and the newest model, but not the earlier one. I have a guy who is going to fit it for me but he didn't know which one to order because he said it didn't seem to be a standard size.

Please help!

Thanks in advance
