The BSD Barrier is all about function. You get a solid chainring with an integrated guard that can withstand impacts and still remains lightweight.
Whether 25T or 28T – both versions come with 1/8" teeth and, thanks to adapter rings, fit 19, 22, or 24 mm crank axles. The plastic guard sits neatly on the chainring and does what it promises.
Visually simple, functionally well-designed – this part fits into almost any setup, whether street, park or trails. Simply mount and ride.
