Product Description

Product Descritpion:

The bottom bracket of a bicycle serves a crucial role in connecting the crankset to the bicycle frame and enabling smooth rotation. Typically, bottom brackets have a long lifespan, enduring thousands of miles or 1-2 years for most riders. However, exposure to moisture or frequent rides in dirt and mud may necessitate more frequent replacement.

Selecting the right replacement bottom bracket can be challenging due to the existence of various bicycle bottom bracket standards. To simplify this process, we offer a range of bottom brackets that adhere to different standards.

If the current option does not align with your bike's specifications, we provide a comprehensive chart as below with alternative choices.

I picked this up to replace the worn out bottom bracket on my gravel bike (73mm BB width) with a SRAM Rival 1 GRX crankset. It fits like it should and was an easy swap to get rid of the creaking I had from the previous one. It continues to work well after swapping onto my vintage road bike (68mm BB width) with a SRAM Force crankset, as it included the spacer for the non-drive side. Highly recommend if you're needing a new BSA bottom bracket.
