💡 What does a bike bottom bracket actually do? A bottom bracket connects your crankset to the frame so your pedals turn freely and efficiently. - It threads into the BSA shell to create a stable spin zone for the axle. - The sealed design helps keep out mud water and trail grit on fat bikes. - Proper fit with the right shell width gives better power transfer and less flex.
