hello all,
I bought a Schwinn Tourist at Target a few months back and want to replace the bottom bracket. It is the cup/cone/bearing type. In short, can I use a sealed bottom bracket or must I stay with the cup/cone and bearing type? It is 68 X 127. I'm fairly certain (but not sure) that the TPI is 24. The spindle is square taper. I researched the spindle on the Sheldon Brown site (it is 3S) and it is actually 125 mm wide, but the "symmetrical equivalent" per his charts is 127.
I was looking at the shimano BB-UN55 and figured that one would fit based on my best evaluations. I'm also kind of leery of the plastic end on the shimano part. I've already learned my expensive lesson of buying a bike from target.
Any ideas?
On the other hand, if I should stick with the cup/bearing type, would there be a reasonably priced upgrade?
Any thoughts are appreciated! Thanks!
