I note:

• That this is the first appearance in an advert of a Shimano Crane GS of any sort.
• That the version of Crane GS is already the second generation version with the adjustable cable outer stop.
• That the words Dura-Ace are visible on the centre-pull brakes. I believe this was the first component to carry this hallowed name.
