Using this Promax EX - 2 bottom bracket is straightforward.

Then, carefully install the bottom bracket into the shell. When you're using the bike, enjoy the smooth pedaling thanks to the low - friction seals and custom sealed bearings. As for maintenance, regularly clean the bottom bracket to keep the seals working well. Check for any signs of wear on the bearings. If you notice any unusual noise or rough pedaling, it might be time to inspect or replace the bearings. Avoid exposing the bottom bracket to excessive moisture and dirt, as this can reduce its lifespan.
