I have a new (to me, it's really used) bike with a Dura-Ace bottom bracket. Based on the PO's notes, it's due for servicing. I'd at least like to open it up and take a look for peace of mind.
However, I've never worked on this exact model. It's a last-generation, 9-speed Dura Ace bottom bracket. Park Tool's website lists the following for adjustable bottom bracket service:
-Repair Stand, holds bike secure for easy work.
-Lockring Spanner, such as HCW-5
-ShimanoŽ Dura-Ace 7700 and XTR 950 lockrings use BBT-7.
-Adjustable cup spanner, such as SPA-1 or SPA-6. ShimanoŽ Dura-Ace adjustable cup uses BBT-2.
-Grease PPL-1 PolylubeŽ 1000
-Marking pen, and masking tape.
Can someone please confirm or deny which of these I'll need? I don't own every item on that list and I don't want to just blindly buy tools if I don't need them - I'm not sure of the model number for my part (is it a 7700?) so I'm not clear on what I'll need. My take on it is that I'll need BBT-7, BBT-2, and a generic lockring spanner. Is that correct? Or do I need the adjustable cup spanner (SPA-1 or SPA-6)?
Also, if someone knows the ball bearing diameter, that would be great.
Thanks in advance!
