Designed to bring Dura-Ace and Ultegra-derived engineering within reach of more riders, the FC-R7100 delivers credible performance for training, sportives, and competitive amateur racing. Available in both 50\/34t and 52\/36t chainring configurations, it covers the full range of road riding demands.\u003c\/p\u003e\n\n\u003cp\u003eThe FC-R7100 adopts a \u003cstrong\u003ehollow-forged construction\u003c\/strong\u003e on the right crank arm — a design approach trickled down directly from higher-tier Shimano groupsets — reducing weight without sacrificing the rigidity you need when putting down power on a climb or accelerating out of a corner. The 4-arm asymmetric spider is purpose-built for Shimano's 12-speed chain and direct-mount chainrings, ensuring precise, consistent shifts across the cassette. Crank arm length options run from 160mm through to 175mm, so riders of different proportions can dial in their fit rather than compromise on it.\u003c\/p\u003e\n\n\u003ch3\u003eShimano 105 7100 Crankset Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eCompatibility: Shimano 12-speed road (105 Di2 and mechanical)\u003c\/li\u003e\n  \u003cli\u003eChainring options: 50\/34t (compact), 52\/36t (mid-compact)\u003c\/li\u003e\n  \u003cli\u003eCrank arm lengths: 160mm, 165mm, 170mm, 172.5mm, 175mm\u003c\/li\u003e\n  \u003cli\u003eConstruction: Hollow-forged right crank arm\u003c\/li\u003e\n  \u003cli\u003eSpider: 4-arm asymmetric direct-mount design\u003c\/li\u003e\n  \u003cli\u003eBottom bracket interface: Shimano press-fit or threaded (sold separately)\u003c\/li\u003e\n  \u003cli\u003eFinish: Matte black\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrickle-down construction from the top of the range.\u003c\/strong\u003e The hollow-forged right arm is a manufacturing process Shimano reserves for its higher groupsets — on the 7100, it means you get a crank that is meaningfully lighter and stiffer than what you would find on a purely entry-level offering, without paying for flagship branding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect-mount chainrings for clean, dependable shifting.\u003c\/strong\u003e The 4-arm direct-mount spider is designed to work in precise harmony with Shimano's 12-speed chain and Hyperglide+ cassette technology — meaning shifts stay snappy and reliable over the course of a long ride, not just in the car park before the start.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFive crank arm lengths across both chainring options.\u003c\/strong\u003e Fit matters more than most riders give it credit for.
