Serious longshot here!
Need to remove a DS Dura Ace 7700 BB track cup.
The tool required is a 6 prong lockring tool like the pic.
Just need a quick borrow. Going to replace it with a 5500 for road use.
Ok, had to bite the bullet and buy one; even that wasn't an easy task.
Will be up for sale soon along with the bottom bracket!
