Carbon construction increases both vertical and horizontal stiffness compared to the alloy version — meaning more of your pedaling force reaches the drivetrain rather than flexing away into the crank body.\u003c\/p\u003e\n\n\u003cp\u003eRotor's Twin Leg design addresses a specific problem: power lost to axle torsion when force is applied through the left pedal. By balancing the load more evenly across the structure, the arms are designed to reduce those losses and keep your output consistent through the full pedal stroke. The 30mm axle interface is built for straightforward assembly with a secure, rattle-free fit, and full compatibility with Rotor's 1x and 2x direct-mount chainrings means you can configure the crank to suit your gearing needs without adapters or compromises.\u003c\/p\u003e\n\n\u003ch3\u003eRotor Aldhu Carbon 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 Carbon fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAxle interface:\u003c\/strong\u003e 30mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainring compatibility:\u003c\/strong\u003e Rotor 1x and 2x direct-mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable lengths:\u003c\/strong\u003e 155mm, 165mm, 170mm, 172.5mm, 175mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight savings:\u003c\/strong\u003e Approximately 100g lighter than aluminum Aldhu arms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Rotor","offers":[{"title":"Black \/ 155mm","offer_id":43517797171244,"sku":"C02-117-13010-0","price":299.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 165mm","offer_id":43517797204012,"sku":"C02-117-17010-0","price":299.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 170mm","offer_id":43517797236780,"sku":"C02-117-19010-0","price":299.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 172.5mm","offer_id":43517797302316,"sku":"C02-117-20010-0","price":299.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 175mm","offer_id":43517797400620,"sku":"C02-117-21010-0","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/rotor-aldhu-carbon-crank-arms-9134306.jpg?v=1771298649","url":"https:\/\/ricycles.com\/products\/rotor-aldhu-carbon-crank-arms","provider":"RA Cycles","version":"1.0","type":"link"}
