{"product_id":"rotor-r-hawk-crank-arms","title":"Rotor R-Hawk Crank Arms","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eRotor R-Hawk Crank Arms\u003c\/strong\u003e are built around a simple premise: remove every gram that isn't doing structural work. Rotor achieves this through Trinity drilling — three full-length longitudinal bores running through each arm — a technique that strips weight without compromising the stiffness that MTB riding demands. The result is a CNC-machined 7055 aluminum arm that comes in at 665g for the complete setup (175mm arms, standard thru-axle, and 30T Q-Ring).\u003c\/p\u003e\n\n\u003cp\u003eThese are arms only — to complete the crankset you'll need a Rotor axle (available in standard and Boost spacing), a chainring (1x only, with round and Q-Ring options), and crankarm bumpers if your setup calls for them. The 30mm spindle interface is broadly compatible with most bottom bracket standards built around a 30mm spindle, including English-threaded shells of varying widths. Crankarm fixing bolts are included.\u003c\/p\u003e\n\n\u003ch3\u003eRotor R-Hawk Crank Arms Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e CNC-machined 7055 aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 665g (175mm arms, standard thru-axle, 30T Q-Ring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLengths available:\u003c\/strong\u003e 165mm, 170mm, 175mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle diameter:\u003c\/strong\u003e 30mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrivetrain:\u003c\/strong\u003e 1x only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Rotor","offers":[{"title":"Black \/ 165mm","offer_id":43518007115820,"sku":"C02-098-17010-0","price":129.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 170mm","offer_id":43518007214124,"sku":"C02-098-19010-0","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 175mm","offer_id":43518007312428,"sku":"C02-098-21010-0","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/rotor-r-hawk-crank-arms-4040207.jpg?v=1771298595","url":"https:\/\/ricycles.com\/products\/rotor-r-hawk-crank-arms","provider":"RA Cycles","version":"1.0","type":"link"}
