It most certainly is a Bridgestone logo on the bottom bracket shell. Any idea if they ever made pro level racing frames?
Just checked the seatpost and it is 26.8mm. Fits like a glove too which makes me suspect it's not Reynolds tubing. Isn't that 531 logo a 70s style anyways? Seems a bit early for this particular bike's construction style.
