Sram Red E1 Flattop 12 Speed Chain 126L w/Powerlock

We’ve crafted the lightest, most durable chain yet, with HollowPin construction that’s stronger and more efficient than before. The Flattop design narrows the chain for quieter, smoother shifts, while hard chrome plating protects wear parts for longer life. It’s cutouts on both plates drop weight without compromising strength, giving you a chain that’s lighter, faster, and built to last.
