One-Piece CNC Monoblock Engineered From The Drivetrain Up

Co-developed by INCOLOR and NEXGA, the OCTOPUS (OC1) unifies the spider, chainrings, and power measurement system into a single high-rigidity component. By eliminating traditional chainring bolts and separate spider interfaces, it delivers instantaneous power transfer, class-leading weight savings at just 179g, and lab-verified ±1.0% accuracy.

Integrated Spider & Chainring Architecture

Precision CNC-machined from a custom high-strength aluminum alloy, the OCTOPUS features an 8-arm spider architecture that merges structural reinforcement directly into the chainring body. This high-rigidity construction eliminates flex under peak sprint loads for more direct, responsive power transfer.

179g Featherweight Performance

Tipping the scales at a mere 179g (50/34T configuration), the OCTOPUS undercuts popular aftermarket spider-and-chainring combinations on both weight and value:

INCOLOR × NEXGA OCTOPUS (50/34T): 179g (30g lighter than Carbon-Ti + Sigeyi)
Carbon-Ti + Sigeyi AXO SL (50/34T): 209g
Shimano Dura-Ace + Sigeyi AXO SL (50/34T): 215g
Skypivot + Xcadey (50/34T): 278.5g

8 Strain Gauges & Pro-Level Accuracy (±1.0%)

Equipped with 8 integrated strain gauges distributed symmetrically around the 8-arm core, the OCTOPUS captures omnidirectional pedaling forces with a linearity error below 1%, 47.3% less measurement variation, and less than 0.8% power deviation when shifting between big and small chainrings.

Real-World Road Validation: Benchmarked head-to-head against the Favero Assioma PRO RS over a 62-minute road test, the OCTOPUS achieved a 0.9727 Pearson correlation coefficient (r) (Average Power: 177.41W vs. 178.27W) alongside boosted RF antenna efficiency (46.88% efficiency / 3.92 dBi peak gain) for zero-drop ANT+ and Bluetooth 5.0 connectivity.
