{"product_id":"rotor-r-raptor-crank-arms","title":"Rotor R-Raptor Crank Arms","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eRotor R-Raptor Crank Arms\u003c\/strong\u003e were designed around a straightforward idea: one set of arms that can adapt to multiple bikes, bottom bracket standards, and chainring setups rather than locking you into a single configuration. The arms are CNC-machined from 6082-series aluminum — the same material Rotor uses throughout their component lineup — for a stiffness-to-weight ratio that a traditional crank-and-spider arrangement struggles to match.\u003c\/p\u003e\n\n\u003cp\u003eThese arms are the foundation of the Rotor modular crank system. They attach to a 30mm spindle — compatible with nearly any bottom bracket standard that accepts a 30mm axle, including English-threaded shells of varying widths — and are designed for 1x drivetrains only, with support for both round and Q-ring chainrings. Crankarm fixing bolts are included. To complete the build, you'll need a compatible Rotor axle, your chosen chainring, and optionally crankarm bumpers — all available separately.\u003c\/p\u003e\n\n\u003ch3\u003eRotor R-Raptor 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 6082 aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle diameter:\u003c\/strong\u003e 30mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainring compatibility:\u003c\/strong\u003e 1x only — round or Q-ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable lengths:\u003c\/strong\u003e 165mm, 170mm, 175mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem weight (175mm arms, standard axle, 30T ring):\u003c\/strong\u003e 715g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Rotor","offers":[{"title":"Black \/ 165mm","offer_id":43518008295468,"sku":"C02-099-17010-0","price":69.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 170mm","offer_id":43518008328236,"sku":"C02-099-19010-0","price":69.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 175mm","offer_id":43518008361004,"sku":"C02-099-21010-0","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/rotor-r-raptor-crank-arms-8609019.jpg?v=1771298594","url":"https:\/\/ricycles.com\/products\/rotor-r-raptor-crank-arms","provider":"RA Cycles","version":"1.0","type":"link"}
