💡 How does a bottom bracket affect bike pedaling efficiency and power transfer? A square taper bottom bracket keeps the crank turning freely while holding proper chain alignment across different riding conditions. - BSA threading ensures solid fit in 68mm shells without extra adapters - Sealed cartridge bearings block out dirt and water on trails or streets - Chainline stabilizer reduces flex so shifts stay crisp under load - Hollow spindle trims weight without losing strength for daily rides
