Power2Max’s new power meter spider is 60g to 80g lighter, cheaper, smaller and works with more brands of crank arms. For those looking to add power, that’s a win x 4.
The new version will fit Cannondale’s HollowGram, Specialized’s S-Works (old and new, as long as they have the detachable spider) and SRAM S-series and Force carbon cranks.
The battery case is a bit smaller, and the outer section of the spider is more machined out. That makes them up to 80 grams lighter depending on BCD.
It’s also been trimmed down on the inside, making it one of the few if not only crank based models that’ll fit the wider BB386EVO frames.
It’s $1,050 and, in addition to the models listed above, will work with Rotor cranks.
They also have a spider that’ll hold Shimano’s new 4-bolt chainrings (DA, Ult), but use a Rotor crank arm. More road options will come, plus mountain bike and track options.
The SRAM model shows the gray color scheme. They also have red and a few others, including an American flag and other nationality motifs.
Or, you can still get the original version, starting at just $899 with FSA Gossamer crank arms. Add Praxis chainrings to the bundle and you’ve got a complete power meter crankset for $1,000.
They use a normal CR2450 battery that’s user changeable. It’s good for 200 to 400 hours depending on climate. They claim a +/- 1-2% accuracy and auto zeros itself when you stop pedaling.
They sell a converter that switches it from ANT+ to Bluetooth, too.
