{"title":"Rotor","description":"\u003cdiv class=\"collection-header\"\u003e\u003cp\u003eRotor is the Spanish company that built its entire philosophy around one engineering problem — eliminate the dead spot in the pedal stroke. The \u003cstrong\u003eRotor\u003c\/strong\u003e collection at RA Cycles covers the full range of their componentry: Q-Rings (oval chainrings designed to load force through the stroke’s power phase and ease off at top and bottom dead center), alongside NoQ round chainrings, 3D+ cranks, FLOW Aero cranksets, and three tiers of crank-based power meters. The INPower measures left-leg power from a single-sided crank; the 2INPower captures both legs independently for a true dual-sided picture. Whether you’re adding a Rotor power meter to an existing build or upgrading to the OCP-adjustable Q-Ring system, this collection covers it — over 100 products across road, MTB, gravel, and triathlon applications.\u003c\/p\u003e\u003c\/div\u003e","products":[{"product_id":"rotor-2inpower-crank-arms-for-direct-mount-chainrings","title":"Rotor 2INPower Crank Arms for Direct Mount Chainrings","description":"\u003cp\u003eRotor’s 2INPower  Crank for Direct Mount Chainrings  power  meter is light and accurate thanks to placement of four strain gauges in the  thru-axle and two in the right crankarm.

These can be picked up by ANT+ head units, Bluetooth  head units, smartphones, tablets, and computers (check yours for specific app  and program compatibility). Thanks to the Bluetooth signal, you can utilize  Rotor’s Torque 360 metrics for dialing in your pedal stroke as well as their  OCA software for determining what, position your Rotor Oval chainring should  sit out for optimal power transfer.

It also means that Rotor has the space to  install circuitry, strain gauges, and a battery inside.

They also come with  the requisite lock ring tool. You’ll need to choose whether you go with Rotor’s  one-piece Direct Mount (DM) Round or Oval chainrings or Aldhu four-arm spider. In  all cases, the spider is splined and slides onto the inside of the right  crankarm from the left side and is secured to the splines with the lock ring.

A positioning guide is included to help you find the right setting for your pedaling style.\u003c\/p\u003e\n\n\u003ch3\u003eRotor Q-Ring Aero Red Outer Chainring Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eMaterial: CNC-machined 7075 aluminum, solid aero plate construction\u003c\/li\u003e\n  \u003cli\u003eFinish: Red anodized\u003c\/li\u003e\n  \u003cli\u003eAvailable BCD: 110mm or 130mm\u003c\/li\u003e\n  \u003cli\u003eAvailable tooth counts: 50t, 52t\u003c\/li\u003e\n  \u003cli\u003eOvality: 10%\u003c\/li\u003e\n  \u003cli\u003eChainring positions: OCP3 (three adjustable positions)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Rotor","offers":[{"title":"110bcd \/ 50t \/ Red","offer_id":43595057463340,"sku":"C01-002-11020-1","price":99.99,"currency_code":"USD","in_stock":false},{"title":"110bcd \/ 52t \/ Red","offer_id":43595057496108,"sku":"C01-002-09020-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"130bcd \/ 52t \/ Red","offer_id":43595057528876,"sku":"C01-001-09020-1","price":99.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/rotor-q-ring-aero-red-outer-chainring-8359253.jpg?v=1771294456"},{"product_id":"rotor-q-ring-aero-outer-chainring","title":"Rotor Q-Ring Aero Outer Chainring","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eRotor Q-Ring Aero Outer Chainring\u003c\/strong\u003e takes the brand's well-established oval chainring concept and closes the plate entirely — a solid, CNC-machined disc of 7075 aluminum where a standard ring would have open cutouts.

This is an innovative crank-based two-sided measuring device  that makes up for the deficiencies found in other power meters. With an  accuracy that can’t be beat and a spider which can accommodate just about all  110mm bolt circle diameter chainrings, and the ability to work with non-round  rings, the 2INpower is unique and welcome to the market. \u003c\/p\u003e\n\u003cp\u003eIf you’re wondering where the strain gauges are hiding,  there are four inside the right crankarm and another four the axle. The axle  also contains the motherboard and rechargeable battery, and the end cap the  antenna. This internal placement of the gauges means that the unit isn’t  temperature-sensitive, and the need to calibrate of adjust the offset is almost  non-existent. You’ll do it on install of pedals, of chainrings, so you’ll do it  when you first install the cranks, then after 30 hours of riding, and pretty  much only when you re\/install pedals or chainrings. \u003c\/p\u003e\n\u003cp\u003eThe crank measures both left and right side power-with the  right arm measuring flexion and the axle measuring the torsion from the left  arm. The ANT+ and Bluetooth Smart signals are sent from the cranks is on as  long as the cranks are moving, which improves the accuracy of the power reading.  Rotor puts the margin of error at less than +\/- 1%.\u003c\/p\u003e\n\u003cp\u003eThere are additional benefits to the constant stream of data  being sent out from the crank as you pedal. It’s one thing if you’re using  round chainrings, as crankarm speed is fairly constant--though in low-cadence  situations, the constant stream is a help-it’s another when you’re using  non-round rings. Like Rotor’s Q and QXL rings. When you’re pedaling these  rings, your crank speed is not constant, it constantly ebbs and flows. So  accuracy with these rings is much greater. The data can be seen in some ANT+  equipped head units. But the real plus is when you utilize Rotor’s free  software. You can use their Torque 360 graph to figure out which Rotor ring is  best for your pedaling style, and exactly how to orient the rings, something  Rotor calls OCA or Optimum Chainring Angle. \u003c\/p\u003e\n\u003cp\u003eThe software can be used to analyze your pedal stroke  post-ride, but it also can be utilized during indoor riding sessions. You can  watch in real-time your stroke and how small changes can affect power. There’s  even an advanced training mode, where the samples sent from the crank double to  enable greater precision for analysis. \u003c\/p\u003e\n\u003cp\u003eThere are two other metrics that are unique to Rotor that  you can utilize to improve your pedal stroke and power output. This also can be  found in the software. One is TE or Torque Effectiveness, which is a ratio o  total torque divided by positive torque. The other is PS or Pedal Smoothness,  which is average power divided by maximum power. Many times, getting more power  is about pedaling better, not harder. And perfecting the stroke could be more  valuable than squeezing greater power out of your body.\u003c\/p\u003e\n\u003cp\u003eRotor, as per their design thinking, works with 7055  aluminum as their material of choice. The crankarms are based off their 3D+  design, with unique machining in the right arm to fit the strain gauges. The  right arm and axle are permanently affixed, while the left arm is loose and is  the one you tighten on to the spindle.\u003c\/p\u003e\n\u003cp\u003eThe bottom bracket spindle is 30mm in diameter and is what  Rotor refers to as UBB30. This means Universal Bottom Bracket. The size is  stiffer than narrower bottom brackets and allows for both the electronics and  the battery to be housed inside, where they are protected from the elements and  minimize any increase in rotating weight. Rotor’s oversized spindle can work  with threaded as well as press-fit bottom brackets. For English and Italian  threaded bottom brackets, you’ll need an UBB bottom bracket, probably from  Rotor. For the press fit standards, BB86, BB30, BB30A, BBright\/BB386EVO, you  should be able to purchase either the proper cups or bearings with the correct  inner diameter.\u003c\/p\u003e\n\u003cp\u003eRotor makes the 2INPower available in the following crank  lengths: 165, 170, 172.5, 175. The bolt circle diameter is 110mm. It’s  primarily designed for road applications, though can certainly work for gravel  and cyclocross, and the chainrings, be they single or double, which are  designed for those disciplines  Weight  for the 172.5 crankset is 645g without chainrings, bolts, or bottom bracket.\u003c\/p\u003e\n\u003cp\u003eThe rechargeable battery is inside the axle and remains  there for the life of it. It should last about 250 hours under normal  conditions. No need to top off when you first install the crank. Charging is  done via a 125cm long magnetic head cable that attaches to the crank on one end  and a USB plug on the other. There’s a light in the crank that indicates  battery life, going from green to yellow to red. When power is low, it will  send a signal out that most ANT+ head units can read warning of low battery  power. The battery is designed to survive 300 charging cycles, so it would be  about 75,000 hours of riding before you’d need to worry (75k hours means if you  rode two hours a day, every day for almost 103 years, you’d exhaust the  battery)\u003c\/p\u003e\n\u003cp\u003eThe cranks come in a box with a bolt to install the left  arm, the charger cable, installation manual, software manual, and a postcard  for using TrainingPeaks at a discount.
