Hi: I saw your post when I was searching for information on changing the bearings on the older PowerTap hubs (the ones with the cone bearing on one side). It is one of the few posts that I've seen that refers to these older hubs, and if you have the time, I was wondering if you would be able to tell me:
1) What the replacement bearing sizes are
2) If you have any tips/advice (or documentation) on the best way to take these apart and re-assemble them
Also, do you know if the freehubs on these are standard Shimano/SRAM or are they a PowerTap special?
I know it's been a while since you made the original post, and I hope you don't mind me responding to it. If you'd rather not clutter up the thread, please feel free to DM me.
Many thanks,
Nick
