What to consider before buying

When choosing a bottom bracket, consider your frame's standard (BSA/English, PF30, BB86/92, etc.) and crankset spindle diameter (24mm vs 30mm, or DUB). For value, the Shimano Ultegra or RaceFace BB92 are great options. If you ride in harsh conditions, invest in a sealed design like Cane Creek 40. Premium Chris King units offer longevity but require a higher budget.
