So a friend helped me a lot today by teaching me how to remove my cranks and bottom bracket. It was cool.
The problem is, we found pitting on the ball bearings and on my spindle. So, we reassembled the front end of my drivetrain, and I rode home weighing my options-- this is where I solicit your sage advice.
I'm on a 1992 Schwinn Criss Cross (it is great for my needs!) and am a grad student. Replacing the bottom bracket cuts into my food budget this month, but I rely heavily on the bike to get around. Paying LBS labor is out of the question, so how do I figure out what size BB to order online for home installation?
Finding 1992 criss cross info on the web is... difficult. One of the bearing cups ( think that's what it is, this is an older, non-cartridge BB) indicated that it is English threaded and the threads per inch, so that helps. But what size?
And how much a risk am I running that I will hurt my frame riding on pitted bearings and spindle? I'm not fat and I commute maybe only 20-30 miles a week depending on groceries runs. A BB is tough to afford right now so a frame is unthinkable...
Thanks for helping me to pull this off cost-effectively!
