Forged from aluminum using Shimano's Hollowtech construction, the FC-7710 keeps weight around 505 grams (without chainrings) while delivering the rigidity that sprint efforts and kilo attempts demand.\u003c\/p\u003e\n\n\u003cp\u003eThe crank uses an Octalink splined interface, designed specifically for use with the Shimano Dura-Ace BB-7710 Track Bottom Bracket. That splined connection — rather than a square taper — creates a stiffer, more consistent engagement between crank and spindle, which you'll notice most when you're out of the saddle and driving hard through the pedals. The 144mm bolt circle diameter is compatible with Dura-Ace FC-7710 track chainrings ranging from 47T to 54T, sold separately. A highly polished anodized finish keeps it looking the part alongside a full track groupset build.\u003c\/p\u003e\n\n\u003ch3\u003eShimano Dura-Ace FC-7710 Track Crank Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Forged aluminum, Hollowtech construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 505g (without chainrings, varies by arm length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter:\u003c\/strong\u003e 144mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrank Arm Lengths:\u003c\/strong\u003e 165mm, 167.5mm, 170mm, 172.5mm, 175mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePedal Thread:\u003c\/strong\u003e 9\/16\" x 20 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Bottom Bracket:\u003c\/strong\u003e Shimano Dura-Ace BB-7710 (Octalink, sold separately)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainrings:\u003c\/strong\u003e Not included — compatible with FC-7710 track chainrings (47T–54T)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"No Color \/ 165mm","offer_id":43520114950188,"sku":"IFC7710A","price":655.0,"currency_code":"USD","in_stock":true},{"title":"No Color \/ 167.5mm","offer_id":43520114982956,"sku":"IFC7710B","price":655.0,"currency_code":"USD","in_stock":true},{"title":"No Color \/ 170mm","offer_id":43520115015724,"sku":"IFC7710C","price":655.0,"currency_code":"USD","in_stock":true},{"title":"No Color \/ 172.5mm","offer_id":43520115048492,"sku":"IFC7710D","price":655.0,"currency_code":"USD","in_stock":true},{"title":"No Color \/ 175mm","offer_id":43520115081260,"sku":"IFC7710E","price":655.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-dura-ace-fc-7710-track-crank-arm-set-9012336.jpg?v=1771297867","url":"https:\/\/ricycles.com\/products\/shimano-dura-ace-fc-7710-track-crank","provider":"RA Cycles","version":"1.0","type":"link"}
