Lemond carbon and steel Versailles. 55 1/2 cm from the center of the bottom bracket to the end of the seat post tube 52 cm from the center of the bottom bracket to the center of the top bar along the seat. Post tube 56 cm from the center of the seat post to be the center of the head tube. I prefer 58-60 but felt pretty good riding this, so it might fit 'big' it is an EXCELLENT RIDE! Smooth yet fast and light. excellent used condition. cant really see any blemishes. the bars are extra double wide wrapped because i have metacarpaltunnel syn. and prefer a fatter grip, but i left the original tape underneith
