Seat post collar

Hey guys, this may be a very silly question, but I have to ask it. I'm looking into a Thomson seat post collar for my bike. I'm pretty sure my bike has one built into the frame, but I'm not sure. How can I tell and how can I take it off if its not built in. I don't even know if they can be built in. I'm very clueless when it comes to seat post collars.
I ride a Bianchi Pista 2004.

Seatpost clamp on the Bianchi Pista is brazed on to the frame. Why do you want to replace it?

Seat post collars are only used on frames with no "ears" brazed (or welded) to the top of the seattube.

Ok cool, thanks for the info. Mine's a little squeaky so I just wanted to see if I could find a way to replace it with a good high quality one.

It shouldn't need replacing to stop it squeaking, are you sure you're tightening it enough?

Oh it's tight. It is possible that its just my saddle. I have a brooks pro and My LBS said it was either the clamp or the saddle

It's almost certainly the saddle, or more likely the saddle clamp.

Is there anyway to lubricate the saddle or something to stop the squeak?

It depends what's squeaking - if it's bits of the saddle squeaking against one another, not really. If it's the clamp, you can take it apart, grease the threads on the bolt (which should ideally be done to most of the bolts on a bike anyway, to stop them seizing) and tighten the whole thing back up. The grease isn't technically necessary, but it means you won't have to tighten the bolt as hard to get enough clamping force. That might stop the squeak.

The above is assuming you have a single-bolt saddle clamp, if there are multiple bolts, don't just gorilla them all down, post a picture.
