When it comes to unusual crankset tech in grand tours, most cycling fans are aware of Froome's oval chainrings; however, unless they obsess over the details of every stage--including the gear ridden by stage hunters like Cummings from Dimension Data--they might miss out on the fact that there are non-Japanese alloy cranks claiming victories in cycling's biggest races. The 2INPowermeter Crankset Package combines Rotor's flagship powermeter with Q-Rings that aim to reduce the dead spot in your pedal stroke. Since the 2INpower crank arms are Cummings' weapon of choice and oblong chainrings have been repeatedly proven in theory by Froome, we can only assume the combination means that you'll be measuring watts with less wasted effort. The theory of oval rings is simple: not every point in the pedal stroke contributes as efficiently to propelling the bike forward, so limiting time spent at those dead angles is a win for watt production. The tech behind measuring those watts is more complicated, so let's start with the internals. Instead of housing them in the spider or in attachments to the crank arms or chainrings, Rotor situates all of the electronics in the spindle. This provides more protection against the elements (be they rain, snow, or tarmac encountered during the inevitable user error), and it also helps to tidy up the crank's silhouette by eliminating bulbous protrusions at the crank arm/chainring interface--of course, Rotor's typically aggressive, Euro-race graphical treatment and iconoclastic chainring designs still manage to stand out. While the electronics are all spindle-bound, the power measurement circuit encompasses both the spindle and the right crank arm, with both receiving four strain gauges for a total of eight. This seems excessive in an industry where five strain gauges is the high end of normal, but incorporating more gauges reduces the chance that external conditions (read: rapid changes in temperature) can adversely affect the 2INpower's accu..
