What would this mean?

My guess is it's a custom Legend of some sort, but we don't have LS on our list. Perhaps a Legend ST? Legend ST would be a level top tube Ti frame with a carbon wishbone seat stay. The Legend was offered in ST and DKS versions in 2003, but we don't have the model codes for them in our list.

C = custom geometry

LS = model

53 = size, seatpost center to center or virtual if it has a sloping top tube

757 = the 757th of that model frame built

If you have other details about the frame perhaps the model can be determined.

This SN is for a bike up on ebay. It looks to be a level TT Legend with wishbone carbon seatstays.

The owner does not have the geo numbers or the original build sheet, but what you say makes sense visually. Now, if I could just figure out the geo numbers. About the only stock numbers I can find are for the fierte, and this guy is measuring in inches.

A custom's geometry could be anything, so correct measurements are going to be important.
