It uses a four-bolt chainring pattern and is only compatible with 1x drivetrains<\/a>.<\/p> According to Rotor, the INspider MTB Shimano Compatible is also among the lightest power meter spiders currently available, weighing a claimed 99g (spider only).<\/p> That\u2019s 50g less than the 110mm BCD INspider power meter<\/a>, designed for use on road and gravel bikes<\/a>.<\/p> Available now, the Rotor INspider MTB Shimano Compatible costs \u20ac499.<\/p> Having recently updated its 2INpower SL power meter<\/a> crankset, Rotor is now updating its mountain-bike specific spider-based power meter<\/a>.<\/p> This type of power meter sandwiches in between the crankset<\/a> and chainrings, and measures the total power produced by both legs.<\/p> As Rotor notes, this has advantages and disadvantages (the perfect power meter doesn’t exist<\/a>, after all).<\/p> On the one hand, spider-based power meters are typically less at risk of impacts, for example.<\/p> On the other, though spider-based power meters measure the total power produced by both legs, they don\u2019t measure each side independently.<\/p> This means they can only estimate left\/right power balance, as opposed to measuring it.<\/p> The Rotor INspider MTB Shimano Compatible is, as the name suggests, compatible with Shimano\u2019s range of direct-mount mountain bike cranksets.<\/p> This includes cranksets from XTR M9100<\/a>, Deore XT M8100<\/a>, SLX M7100<\/a> and, in theory, any other crankset that uses the same direct-mount interface.<\/p> This is a key standard for a power meter brand such as Rotor to target, because while Shimano has made power meter cranksets for road bikes since the introduction of Dura-Ace R9100<\/a> in 2017, it has yet to release a power meter designed for gravel or mountain bike<\/a> use.\u00a0<\/p> As a result, third-party power meter brands such as Rotor, Stages<\/a>, SRM<\/a> and Power2Max<\/a> have looked to exploit this gap in the market.<\/p> The Rotor INspider MTB Shimano Compatible is available now and costs \u20ac499 (international pricing was not available).<\/p> Rotor claims the INspider MTB power meter is accurate to within plus or minus 1.5 per cent,\u00a0and uses accelerometers to measure cadence (meaning no frame magnets are required).<\/p>Now Shimano compatible<\/h2>
