ROTOR has launched its latest power meter called the 2INpower SL Road, touting it as “the lightest dual-sided power meter on the market”, tipping the scales at a claimed 729 grams while fitted with a 50/34T chainring, a 15% reduction in weight over its predecessor.
“Since we launched INspider we have found that many people prefer to ride the spider power meter versus 2INpower purely for weight, even having to give up certain metrics such as true balance or more complicated biomechanics pedalling information,” says Rotor’s Irene Albacete. “Weight reduction was therefore the main goal for the 2INpower revamp, and that’s what we’ve been working on for the past few years, iterating the mechanical design as many times as we needed until we got what we wanted,” says ROTOR.
In order to achieve the 2INpower SL Road’s feathery weight, ROTOR says it relied on its Trinity Drilling System to remove excess material from the right crankarm, shaving away considerable grams while still being able to work with a standard 110×4 spider, as well as with direct mount 1x and 2x chainrings.
Elsewhere, the 2INpower SL Road is IP67 certified, protecting it against rain and road spray, while the electronics have been located inside the spindle in order to isolate it from shock or impact, resulting in an accuracy of +/-1.5% in temperatures ranging from -20°C to 50°C and across all riding conditions, with no rider recalibration required. Moreover, it comes with a software app that offers personalized data and graphs for in-depth data analysis and training platform applications.
Additionally, the 2INpower SL Road is Bluetooth and ANT+ compatible, allowing it to work with virtually any cycling computer, while its lithium-ion battery can provide up to 250 hours of ride time on a three-hour charge.
Designed and manufactured in Spain, the 2INpower SL Road comes in 165mm, 170mm, 172.5mm and 175mm crank lengths with a 30mm spindle that sells for €1,149.
