BUCKLOS BSA Bottom Bracket — Sealed & Ceramic
⭐ Club Checked
Pick the MH500 or MH530 sealed-bearing version for everyday reliability, or the MH800 ceramic version for lower friction — both thread straight into a 68mm or 73mm BSA shell with a 24mm spindle. Three washers are included, so it's a clean, no-shimming swap for a crank that's lost its smooth spin.
