A BB30 setup is tough on bearings due to the narrow space between them, leading to increased wear over time. If durability is your priority, even in harsh conditions, we recommend cross bearings for road bikes. These bearings offer greater toughness, making them ideal for riders seeking longevity and performance. Choose cross bearings for Cyclo-Cross, mountain bikes, and commuting. Kogel's ceramic bearings are an excellent choice, combining smooth efficiency with superior durability, perfect for off-road rides or daily commutes.
