Shimano BICYCLE CHAIN, CN-M7100, SLX

A 12-speed mountain bike and road chain built for SLX-tier and 105-tier drivetrains, the Shimano CN-M7100 SLX/105 Chain runs Hyperglide+ tooth profiling and SIL-TEC surface treatment to keep shifts crisp under load and resist grime buildup on long off-road days. Extended inner plates improve chain retention through chunky terrain, and the included SM-CN910-12 quick-link makes wheel-out maintenance tool-free. The 12-speed chain measures 5.25mm wide, ships at 126 links, and weighs 252g, which puts it at the right spot in the Hyperglide+ ecosystem for SLX M7100 mountain builds and 105 R7100 road groupsets without crossing into XT or Dura-Ace pricing.
