The Theory American Bottom Bracket Kit includes 2 precision sealed bearings, press-in American BB cups, internal spacer, drive and non-drive side dust caps, and several spacers to work with.
Be sure to grease up your new bottom bracket kit while installing it. This makes installation easier and keeps the bearings running smooth with a longer lifespan. Find grease here.
