Onza T-pro Bottom Bracket Problem

[CastroManiac]

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

put loctite or nutlock whatver you want to call it on both sides of the bottom brackets threads and then put it back in and thighten the crap out of it then leave it like over night and the loctite will set keeping the bb in.

hope this helps

are you sure your putting it in the right way?

I have a t-pro either an 05 or 06.

They have an oversized BB shell. So you can only use an oversized BB.

I tried to get one from tarty and supercycles but they don't sell them anymore.

You have to either use oversized cups from an oversized BB or try and find one somewhere (possibly ring up onza) Also, im pretty sure they only come in 119 length axle square taper.

If you use a non-oversized BB it will not tighten up properly.

The length is 73mm as opposed to a normal BB which is about 63mm (i think)

Aight noted. Will try to get an oversized BB from one of my friend to see if it fits, if not i'll ring up onza then. Thanks alot for the help guys.
