Ten-speed drivetrains put real demands on chain construction. The plates need to be narrow enough for tight cog spacing while still handling the lateral flex of front derailleur shifts. SRAM's PC-1071 addresses this with hollow pins that reduce weight without sacrificing the rivet integrity that keeps the chain together under load. The chrome-hardened pin surface resists the wear that accumulates at every link-to-cog contact point.

The PC-1071 uses SRAM's PowerLock connector for tool-free installation. You line up the special link, apply pedal pressure, and the chain snaps together with an audible click. No chain tool required for initial setup, though you'll still need one if you're sizing the chain down from its stock 114 links. The PowerLock is designed as a single-use connector, so keep a spare in your saddle bag if you're the type who removes the chain for deep cleaning.

Compatibility runs across SRAM's 10-speed road and mountain groups, plus Shimano 10-speed systems. The 5.9mm inner width matches the tooth profile on both platforms. If you're running a mixed drivetrain with a SRAM cassette and Shimano shifters, or vice versa, this chain bridges the gap without compatibility headaches.... Read More
