Help me understand my Dura Ace 7400 hub.
Before I mess it up.
Got the Uniglide cassette off no worries. Scrubbed the years of nicotine off the body, spokes, and rims. Now it's time to grease the bearings.
The assembly looks the same as most hubs except for some dimpled plastic caps that say "open" and "close".
What is that? A seal? Does it need to be turned to open before I grab the spanners? They're 35 years old and Uniglide, so if I break them, they're gone.
Speaking of Uniglide. Am I correct that according to Sheldon, I cannot do a HG freehub on this? The way I read it was that you can swap 6, 7, and 8 UG bodies but cannot put a HG on for Dura Ace.
So if I want to expand my 13-24 6 speed cluster, I need a Dremel tool, a 7 speed cassette that comes apart, and to guard my 13 tooth threaded cog with my life. This is a pretty cheap and viable option actually if it works.
