The result is a modular crank system with a significant reduction in weight and a significant increase in rigidity. Made from high-end carbon and beautifully finished, the Aldhu Carbon\u003cbr\u003e a jewel on every bike. This allows weight increases caused by disc brakes to be elegantly compensated without losing the necessary rigidity.\u003c\/p\u003e\n\n\u003cp\u003e \u003cstrong\u003eHow much lighter and stiffer is Aldhu Carbon?\u003c\/strong\u003e \u003cbr\u003eROTOR's first generation aluminum ALDHU® weighs just over 600 g with a 172.5 mm crank arm length and 50\/34 direct mount chainrings, a top value for extruded and CNC-machined cranks. Utilizing the advantages of high-end carbon fiber, the new carbon crank arms save around 100 g and the total weight drops to \u003cstrong\u003e523.5 g!\u003c\/strong\u003e\u003cbr\u003e At the same time, the absolute vertical and horizontal stiffness of the cranks was increased by 11% and 36.1% respectively.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003ePossible crank combinations\u003c\/strong\u003e\u003cbr\u003e Every cyclist has individual demands on the comfort and performance of their equipment and ultimately these determine the riding experience and performance. \u003cbr\u003eThe ALDHU® carbon cranks can be equipped with different types of chainrings. Round or oval, via direct mount or classic with a spider and also in aero versions. Various axes make the crank compatible with almost every bike on the market and also fit perfectly into groups from other manufacturers. Even a power meter spider can be integrated into this modular infrastructure.\u003cbr\u003e ROTOR has divided the possible crankset combinations into four categories: Standard, Superlight, Aero, and Full Aero with 1x and 2x configurations (Standard offers 2x).\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eTwin Leg Technology\u003c\/strong\u003e \u003cbr\u003eALDHU® carbon crank arms were developed in combination with ROTOR's 30mm axles. The patented interface between crank arms and axle offers easy assembly with a tight fit. The design solves a specific problem, namely preventing power losses caused by axle torsion under pedal force. ROTOR axles effectively reduce power losses. The balance achieved to minimize these losses is what we at ROTOR call\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eOCP Mount\u003c\/strong\u003e\u003cbr\u003e OCP technology allows the rider to adjust the alignment of the oval ROTOR Q RINGS® chainrings relative to the crank in degrees. The OCP assembly is based on the combination of three independent elements: axle, right crank arm and spider or DirectMount Q RINGs®. The patented crank interface for DM Q RINGS® enables the most precise adjustment of an oval chainring to date. \u003cbr\u003eThis is the only way to really adjust an oval chainring to the rider's individual needs and pedaling technique and to bring pedaling efficiency, traction control and, above all, the reduction of joint strain to an optimal level.\u003cbr\u003e Thanks to the modular design of ALDHU®, every rider can completely customize their crankset. ROTOR first included this concept in its range in 2017 and has continuously added additional components.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eUpgrades for ALDHU CARBON\u003c\/strong\u003e\u003cbr\u003e If you already have an ALDHU® or VEGAST® crankset, the ALDHU®Carbon upgrade only requires an 8mm Allen key and 2 minutes of time. \u003cbr\u003eEven upgrading a ROTOR INspider power meter can be done in minutes and without any specialist knowledge. This new system offers precise power measurement, cadence, balance values ​​via two proprietary metrics, Torque 360 ​​data and the optimal chainring angle. This perfect and professional, but very easy-to-use combination allows you to optimize your drive yourself!\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eSpider or Direct Mount combination chainring – the choice is yours\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e The ALDHU Carbon is of course compatible with other road bike groups from Shimano, SRAM or Campagnolo and offers future-proof technology thanks to Direct Mount. \u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0767\/9148\/0660\/files\/rotor-aldhu-modularer-aufbau_3770de47-17c0-43f6-a7ac-e6db6d8cbc6a.jpg?v=1701984902\" style=\"width: 700px; height: 330px;\"\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cul style=\"line-height: 20.8px;\"\u003e\n\n\u003cli\u003e Material: Carbon\u003c\/li\u003e\n\n\u003cli\u003e Crank arm length (mm): 165 \/ 170 \/ 172.5 \/ 175\u003c\/li\u003e\n\n\u003cli\u003e Bottom bracket: All 30mm bottom brackets\u003c\/li\u003e\n\n\u003cli\u003e Chainline: Standard: 43.5mm (1x), 44.5mm (2x) \/ Offset: 46mm (1x), 47mm (2x)\u003c\/li\u003e\n\n\u003cli\u003e Q factor: Standard: 147mm \/ Offset: 152mm\u003c\/li\u003e\n\n\u003cli\u003e Pedal thread: Standard 9\/16\"\u003c\/li\u003e\n\n\u003cli\u003e Crank arm weights: 260 g (172.5 mm)\u003c\/li\u003e\n\n\u003cli\u003e Color: CARBON\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"ROTOR Bike","offers":[{"title":"165 mm","offer_id":47310654505300,"sku":"56207-165","price":449.99,"currency_code":"EUR","in_stock":false},{"title":"170 mm","offer_id":47310654406996,"sku":"56207-170","price":449.99,"currency_code":"EUR","in_stock":false},{"title":"172,5 mm","offer_id":47310654439764,"sku":"56207-172","price":449.99,"currency_code":"EUR","in_stock":false},{"title":"175 mm","offer_id":47310654472532,"sku":"56207-175","price":449.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/9148\/0660\/products\/ROTOR_ALDHU_-Carbon-crank_12.jpg?v=1701984926","url":"https:\/\/smpirts.com\/en\/products\/rotor-aldhu-carbon-kurbelarme","provider":"SMParts","version":"1.0","type":"link"}
