The BSD 1991 Half Link BMX chain has become a staple among street and park riders for a reason. This chain is made for those who do not leave their drivetrain to chance and want their bike dialed in with real precision. The half link design allows you to fine tune the chain length down to the smallest detail, keeping the rear wheel exactly where you want it. The result is a tight setup with a direct, quiet feel whether you are sprinting, pumping transitions, or rolling away clean after a heavy grind.
The thicker side plates and solid pins are built specifically for freestyle BMX abuse. It handles sideways loads, hard landings, and the constant stress that comes with real street riding. Full compatibility with 8 tooth drivers makes it a strong choice for modern setups, so you do not have to compromise when building your drivetrain.
BSD has always been about riders first. The brand comes straight out of street riding culture, designing parts for real spots, not just for catalog photos. The 1991 Half Link chain reflects that mindset perfectly. Clean, functional, and brutally honest. It is the kind of component that feels right when your bike takes hits, your legs are tired, and you still push one more run. This is not about looks. It is a tool made to be ridden hard.
