MAAKE has picked one of its products, the XPOWER-S GEN2 spider power meter, which fits between the crank and the chainrings.\u003c\/p\u003e\u003ch2\u003eOver ten years of power measurement\u003c\/h2\u003e\u003cp\u003eXcadey is the brand of Guangzhou Zhunchuang Technology, in Guangzhou, China. It has worked on power measurement since 2013: single-sided and dual-sided power meters first, then in 2019 its first spider power meter, the XPOWER-S, and in 2023 its second generation. Hardware design, firmware, testing and manufacturing all take place at its Guangzhou site. Its power meters are calibrated at different cadences, loads and temperatures, and every product goes through an assembly check, a function test and a final test before packing.\u003c\/p\u003e\u003ch2\u003eWhat a spider measures\u003c\/h2\u003e\u003cp\u003eThe \u003ca href=\"\/en\/products\/xcadey-xpower-s-gen2-power-meter\"\u003eXPOWER-S GEN2\u003c\/a\u003e takes the place of the stock spider, between the right crank and the chainrings. All the torque from both legs goes through it: eight strain gauges measure its deformation, an accelerometer gives the cadence. Xcadey quotes ±1%, or ±3 W at 300 W, and 350 hours of battery life, about eight months at 10 hours of riding a week. The limit lies in the principle: the spider sees the sum of both legs, so left-right balance is only an estimate.\u003c\/p\u003e\u003ch2\u003eWhy MAAKE chose it\u003c\/h2\u003e\u003cp\u003eFor one precise reason: its Easton 110BCD-4S version fits the \u003ca href=\"\/en\/products\/cybrei-gp-3-carbon-road-crank-arms\"\u003eCybrei GP-3\u003c\/a\u003e and \u003ca href=\"\/en\/products\/cybrei-ultra-carbon-road-crank-arms\"\u003eUltra\u003c\/a\u003e crank arms, and turns a carbon crankset into a power meter without touching the cranks or the chainrings.
