Seat clamp bolt advice

[Rawcas]

Almost finished a rebuild on my old commuter frame but I have done the very thing I vowed not to and lost a rather integral part!

My original seat clamp bolt has gone walk about so I need to get a replacement...this is where I need some advice as I'm a bit confused about the correct size and fit to go for.

This is the clamp setup:

Can anyone suggest anywhere online that I can grab a replacement, the original had a small nurl which slotted into the frame to keep it in place. I'd actually like to go for QR if possible, have considered a cheap Ebay job for now, would something like this fit:

All help much appreciated as always.

I've always gone with something like this when the collar / clamp is part of the frame.

Not sure whether it would fit nicely on yours, mind.

I've always gone with bolts since the days when I used my bike for going everywhere, and didn't want my saddle to be so quickly nickable (albeit it's probably not that much slower to use an allen key to slacken off a bolt - but at least they'd have to be equipped).

.... and you can guarantee that the seat post will never seize in the frame!

That's just part of maintenance, though, isn't it.

Nothing to do with how you hold the seatpost in the frame.

Agreed, the seatpost will be checked regularly when everything is topped up, relubed etc. so no issue there.

As for the issues with things being nickable, the bike is securely locked out of site at work...not that I've got £150 worth of carbon shelled Fizik saddle for anyone to nick anyway

SJS seat bolt for £5.10 + postage! That's expensive. I should put my prices up as I have the same thing marked up at £2.
