Planet X Track Frame Sizing

I am about the same height (5.10) and have a 56, the 56 used to be called large.

Anyway you have the correct size.

Maybe you need to adjust the seat forward, bars and spacers, or a shorter stem?

Are the pictures of your own bike?

These are pictures of the actual bike - spanking new Planet X Track Limited Edition - the bike is definitively a tad too big and I would feel more comfortable on a small one (54x54).
I'll put an ad on the track bits for sale then into the main classified forum - not sure how much to ask for it since this exact spec sells for about £1K.
I'll think of a price shortly and get that sorted asap!
