Hello,

I am new here and have a tech question. I have a redline urbis that I bought sued from a buddy of mine. It was all stock except for the BB and crankset. I am looking to replace the BB and crnakset I have now with something more similar to the original specs but the problem is that I know nothing about bikes let alone BB specs and crnakset stuff. What should I look for to ensure the BB I buy will be compatible with my urbis? Thank you!
