Re:
Every single year I need to replace my Scott's UN-55 because it starts to run rough. This year is no exception.
It's not too bad yet, but it was noticeable when riding and certainly so when spinning the crank while holding the BB in my hand.
No amount of protecting the seals with grease etc seems to help, those BBs just don't last more than 3-4000 miles apparently.
So let's try something different, something I can take apart and re-grease at regular intervals.
Of course I didn't have the tools for cup-and-cone BBs, only for cartridge ones. So I had to buy this (also NOS) :
Oh, and to finish it off the postman also delivered a NOS M730 QR for the seat post.
It'll need some cleaning and polishing though, and I may need to shorten the thread by half an inch or so.
My Scott has eyelets for the QR on the seat tube, and IIRC those are not far apart. I'll verify this when I get the frame back from the painter. :mrgreen:
