I've been thinking for a while about converting my cup/cone bottom Bracket to a new sealed cartridge type... what do you guys think?
This is on my 1984 Trek 520, and I love that bike. I bought it brand new in 1983 as soon as the new model hit the floor in my LBS, and I've been riding it ever since. It is my daily commuter and gets about 20 to 25 miles every day rain or shine... so maintenance is an issue for me.
The old girl still has the original Maillard front hub and cup/cone bottom bracket, but I've gotten tired of repacking and adjusting the bearings again and again... so I'm looking at replacing the old BB with a modern one so as to eliminate the maintenance issues.
So I have 2 questions for you folks:
- Since the old cup/cone BB still works perfectly with no noise or problems... should I just leave it alone? Should I just shut up and continue to grease and adjust the BB that has served admirably for 25 years?
- If I do the conversion... what is involved in doing it? Do I need to modify the BB housing or anything? How do I actually shove a cartridge bearing set in there?
I sure appreciate any input that you guys have...
