Hey guys, I've got a T-pro 2005 Model. Yeah, wanna ask what's the length,size and the required details of the bb needed to fit in an onza? I've fitted a UN53 square taper bb but the drivetrain side always comes loose. I then took a monty's ISIS bb and cranks. The same thing happened, the drivetrain part where the shiny part of the bb is loose. What can i do about it? another isis bb? or what you guys recommend? Thanks alot
