OVERFAST Aero Carbon Crank Assembly w/ Alloy/Carbon or Power-Meter Spider
If you’re after the ultimate in aerodynamic drivetrain performance and the precision of integrated power measurement, the OVERFAST Aero Carbon Crank Assembly with alloy/carbon or power-meter spider is built with one mission: maximize speed, minimize drag, and measure your every watt.
OVERFAST didn’t simply build a lightweight crankset—they re-imagined the crank arm geometry to reduce aerodynamic drag in one of the least-considered zones: the drivetrain arms. By narrowing the profile, smoothing transitions and sealing the non-drive side, they’ve crafted a crankset designed to cut resistance at the heart of your pedalling system. The result? A measurable aero benefit that may only save a handful of watts—but over a 40 km time trial, or a long road race, those watts convert into seconds saved and energy conserved when it matters most.
Carbon-arm construction offers both extremely low weight and exceptional torsional stiffness—transferring your pedal strokes directly into forward motion.
For the 28.99 mm (DUB) axle version: ~330 g (165 mm length) weight.
For the 24 mm titanium axle version: ~325 g (165 mm length).
Both versions feature a chainline of 44 mm, and a spider interface that is EASTON-compatible—giving you flexibility in chainring choice and drivetrain specification.
Axle / Spindle Options: 28.99 mm (DUB) or 24 mm (Ti24) — you choose based on your bottom bracket/frame system.
Crank Arm Lengths: 155 mm, 157 mm, 160 mm, 162 mm, 165 mm, 167 mm, 170 mm, 172 mm — covers a wide range of rider sizes and fit preferences.
Q-Factor: 147 mm on the DUB (28.99 mm) version; 148 mm on the 24 mm version.
Spider Type Options: Choose from a CYBREI Alloy Spider, CYBREI Carbon Spider or the Xcadey XPOWER-S Gen2 Power-Meter Spider (available in 4 × 110 BCD or 5 × 110 BCD) — giving you the aero carbon crankset plus full power-measurement capability.
The Xcadey XPOWER-S Gen2 spider-based power meter offers dual-leg power measurement, with claimed accuracy of approximately ±1.0%, giving you reliable data to train and race by.
Battery life of up to ~150 hours, waterproof rating IP67, ANT+ and Bluetooth connectivity — ready for any ride condition or racing environment.
Compatible with a wide array of chainring setups, serving both performance-focused racers and ambitious enthusiasts.
If you’ve already optimized major components (aero frame, deep-section wheels, narrow handlebars, aero helmet) and you’re chasing that extra marginal gain, then upgrading to this crankset with power meter spider becomes part of your performance ecosystem. Because when every part of your drivetrain, your fit, your bike system works together, you’re not just buying a crankset—you’re investing in watts saved, consistency gained, and output you can measure.
Time-trialists and triathletes who demand every possible aero advantage and require accurate power data.
Road racers upgrading their drivetrain to the absolute performance end.
Cyclists who value precision, data-driven training, and component engineering that supports their goals.
Anyone seeking a high-end crankset that combines carbon performance, aero refinement, and integrated power measurement.
Axle Diameter Options: 28.99 mm (DUB) or 24 mm (Ti24)
Crank Arm Lengths: 155–172 mm (various)
Q-Factor: 147 mm (DUB) / 148 mm (24 mm)
Chainline: 44 mm
Spider Interface: EASTON compatible
Weight: ~330 g (165 mm, DUB) / ~325 g (165 mm, 24 mm)
Power Meter Spider (Xcadey XPOWER-S Gen2): Dual-leg, ±1.0% accuracy, IP67, ~150 h battery, ANT+/Bluetooth, supports 4×110 BCD or 5×110 BCD chainrings.
For riders who accept nothing but the best—this is where aero meets data. The OVERFAST Aero Carbon Crank Assembly w/ Power-Meter Spider gives you performance you can feel, measure, and rely on.
