The Rant Bang Ur Mid Bottom Bracket Kit includes all of the parts to replace a worn out BB. The kit includes: 2 Mid size precision sealed bearings, 1 aluminum internal spacer (51mm), 2 aluminum cone spacers with laser-etched Rant logos, and 4 crank arm spacers to dial in the chain alignment.
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.
