{"product_id":"shimano-fc-r9100-chainring","title":"FC-R9100 Dura-Ace Chainring","description":"\u003cp\u003eThe Shimano Dura-Ace FC-R9100 chainrings are genuine replacements for worn or damaged rings on FC-R9100 and FC-R9100-P cranksets. Rings wear out long before the crank arms do, so fitting fresh ones restores the crisp, quiet shifting the groupset was built around.\u003c\/p\u003e\n\u003cp\u003eThe outer rings use HOLLOWGLIDE construction, a hollow-forged design that adds rigidity and saves weight at the same time. Taking the flex out of the outer ring is what you notice on the road: the chain climbs cleanly and predictably, staying precise even when you shift under high load.\u003c\/p\u003e\n\u003cp\u003eTooth profiles are developed to run only with 11-speed chains, giving closer contact between chain and ring and more efficient power transfer. Rings are sold individually and the inner and outer are matched pairings, so a 53T-MW outer runs with a 39T-MW inner, and a 52T-MT outer with a 36T-MT inner. Check which pairing your chainset uses before ordering.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Shimano replacement chainring for Dura-Ace FC-R9100 and FC-R9100-P cranksets\u003c\/li\u003e\n\u003cli\u003eHOLLOWGLIDE hollow outer chainring construction for improved rigidity and reduced weight\u003c\/li\u003e\n\u003cli\u003eRemoving outer chainring flex sharpens front shifting, staying precise even under high load\u003c\/li\u003e\n\u003cli\u003eTooth profile developed specifically for 11-speed chains for better contact and power transfer\u003c\/li\u003e\n\u003cli\u003e110 mm bolt circle diameter with a four-arm fitting\u003c\/li\u003e\n\u003cli\u003eRuns with Shimano HG 11-speed chains\u003c\/li\u003e\n\u003cli\u003eSold individually, in matched pairings: 53T-MW with 39T-MW, 52T-MT with 36T-MT\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct type: Chainring\u003c\/li\u003e\n\u003cli\u003eSpeed: 11 speed\u003c\/li\u003e\n\u003cli\u003eDiscipline: Road, Time Trial and Triathlon\u003c\/li\u003e\n\u003cli\u003eBolt circle diameter: 110 mm\u003c\/li\u003e\n\u003cli\u003eChainring fitting: 4 arms\u003c\/li\u003e\n\u003cli\u003eColour: Black\u003c\/li\u003e\n\u003cli\u003eCompatible chain: Shimano HG 11-speed\u003c\/li\u003e\n\u003cli\u003eSizes listed: 53T-MW outer ring, 36T-MT inner ring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Black \/ 36T-MT","offer_id":40809766453427,"sku":"Y1VP36000","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 53T-MW","offer_id":58727439073654,"sku":"Y1VP98030","price":164.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/products\/shimano-spares-fc-r9100-chainring-36t-mt-for-52-36t-1179343258.jpg?v=1767692402","url":"https:\/\/www.biketart.com\/products\/shimano-fc-r9100-chainring","provider":"Biketart","version":"1.0","type":"link"}
