Available in compact 50x34 and mid-compact 52x36 chainring options, with crank arm lengths ranging from 165mm to 175mm, it covers a wide range of rider builds and riding styles. Whether you're tackling long climbs, sustained group rides, or criterium-style efforts, the FC-08 is engineered to stay consistent lap after lap.\u003c\/p\u003e\n\n\u003cp\u003eShimano's \u003cstrong\u003eHollowtech hollow-forged crank arms\u003c\/strong\u003e are the structural backbone here — the manufacturing process removes material from inside the arm itself, reducing weight and rotational mass while maintaining the torsional stiffness needed for efficient power transfer. The outer chainring uses Shimano's Hollowglide profile, a tooth geometry designed to work in close cooperation with HG-EV and HG-X11 chains for fast, clean front shifts under load. The inner ring's Hyperglide+ profiling supports smooth upshifts and downshifts regardless of pedaling pressure. It's a system built around consistency, not compromise.\u003c\/p\u003e\n\n\u003ch3\u003eShimano Ultegra FC-08 Crankset 11-speed Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eGroupset compatibility: Shimano Ultegra 11-speed\u003c\/li\u003e\n  \u003cli\u003eChainring options: 50x34 (compact), 52x36 (mid-compact)\u003c\/li\u003e\n  \u003cli\u003eCrank arm lengths: 165mm, 170mm, 172.5mm, 175mm\u003c\/li\u003e\n  \u003cli\u003eConstruction: Hollowtech hollow-forged aluminum crank arms\u003c\/li\u003e\n  \u003cli\u003eOuter chainring: Hollowglide tooth profile\u003c\/li\u003e\n  \u003cli\u003eChain compatibility: Shimano HG-EV and HG-X11 11-speed chains\u003c\/li\u003e\n  \u003cli\u003eBottom bracket interface: Shimano Hollowtech II\u003c\/li\u003e\n  \u003cli\u003eSpeed: 11-speed\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\u003eHollow-forged construction for reduced rotational weight:\u003c\/strong\u003e By removing material from inside the crank arm during forging, Shimano achieves a stiffer, lighter arm than a solid casting would allow — which translates directly to sharper acceleration response and less fatigue over long efforts.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHollowglide chainring geometry for reliable front shifting:\u003c\/strong\u003e The Hollowglide outer ring is shaped to guide the chain efficiently onto and off the ring, giving you predictable front shifts even when you're pushing hard into a climb or sprinting out of a corner.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWide fit range across arm lengths and chainring options:\u003c\/strong\u003e Four crank lengths and two gearing configurations mean this crankset can be dialed in to your biomechanics and terrain — whether that's a compact setup for hilly rides or a mid-compact for flatter courses where you need more top-end range.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"50x34 \/ 165mm","offer_id":43952448143404,"sku":"IFC08AX04A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"50x34 \/ 170mm","offer_id":43952448176172,"sku":"IFC08CX04A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"50x34 \/ 172.5mm","offer_id":43952448208940,"sku":"IFC08DX04A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"50x34 \/ 175mm","offer_id":43952448241708,"sku":"IFC08EX04A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"52x36 \/ 165mm","offer_id":43952448274476,"sku":"IFC08AX26A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"52x36 \/ 170mm","offer_id":43952448307244,"sku":"IFC08CX26A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"52x36 \/ 172.5mm","offer_id":43952448340012,"sku":"IFC08DX26A","price":365.0,"currency_code":"USD","in_stock":true},{"title":"52x36 \/ 175mm","offer_id":43952448372780,"sku":"IFC08EX26A","price":365.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-ultegra-fc-08-crankset-11-speed-1609294.jpg?v=1771294032","url":"https:\/\/ricycles.com\/es\/products\/shimano-ultegra-fc-08-crankset-11-speed","provider":"RA Cycles","version":"1.0","type":"link"}
