It is built around \u003cstrong\u003eHollowtech II\u003c\/strong\u003e, the hollow-forged aluminum crank arm and 24mm steel spindle design that Shimano tunes for the best balance of stiffness, low weight, and efficient power transfer. This is the 172.5mm arm in black with 50\/34T compact chainrings already fitted, so you get a ready-to-install crank and chainring set in one part, with no bottom bracket included.\u003c\/p\u003e\u003cp\u003eShimano gave the R8000 a \u003cstrong\u003ewider gear pitch\u003c\/strong\u003e that adds clearance between the chain and leading teeth, which lets it work cleanly with modern disc road frames running 135mm rear spacing and 410mm chainstays. The 50\/34T compact gearing pairs a usable top end with a friendly climbing ratio, and the crank runs HG-EV and HG-X11 11-speed chains. Add an SM-BBR60 threaded or press-fit bottom bracket to match your frame and it drops straight into any 11-speed mechanical Ultegra, 105, or Dura-Ace build.\u003c\/p\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":52640341623096,"sku":null,"price":365.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0959\/8435\/3592\/files\/shimano-ultegra-fc-r8000-crankset-172-5mm-50-34t.jpg?v=1784071619","url":"https:\/\/dialedcyclinglab.com\/products\/shimano-ultegra-fc-r8000-crankset-172-5mm-50-34t","provider":"Dialed Cycling Lab","version":"1.0","type":"link"}
