11 speed chains run narrower than their 10-speed predecessors, which means tighter tolerances between the inner plates and your cassette cogs. SRAM's PC-1170 chain addresses this with chrome-hardened pins and Flow Link technology that reduces friction as the chain articulates through the rear derailleur pulleys. The hollow pin construction sheds weight without sacrificing the pin diameter needed for durability under load.

The PC-1170 sits in SRAM's mid-tier chain lineup, sharing the same plate geometry as the higher-end PC-1190 but using solid outer plates instead of the hollow treatment found on that model. For most riders, the weight difference between tiers matters less than consistent shifting performance, and the 1170 delivers clean engagement across the cassette range. The PowerLock connector link allows for tool-free installation and provides a secure connection that handles repeated removal for cleaning without wearing out the link.

Chain stretch remains the primary wear indicator regardless of brand, and the PC-1170's chrome hardening on the pins and inner link surfaces extends the interval before your chain checker hits the 0.5% mark. Running a chain past its service life accelerates cassette and chainring wear, so the PC-1170's durability translates to longer component life across your drivetrain. The 114-link length works for most road double setups, though compact cranksets paired with larger cassettes may require adding links from a second chain.... Read More
