Carbon Crankset Series 24 Axle / DUB Axle — T1000 Carbon, EPS Molding, UCI-Tested Stiffness
High-end carbon cranksets built from T1000 fibers with EPS dual-airway internal molding. Developed over three years together with UCI Continental teams and WorldTour riders, our carbon crankset targets maximum stiffness without adding weight. Choose between a 24 mm axle for all standard 24 mm bottom brackets or a DUB axle for SRAM DUB frames, both tuned for 11- and 12-speed drivetrains.
Best Carbon Crankset Upgrade — Lightweight, Stiff, Race-Ready
24 Axle Carbon Crankset — For Standard 24 mm Bottom Brackets
The 24 axle carbon crankset is built around a 24 mm spindle that drops into most 24 mm road bottom brackets. T1000 carbon arms formed with EPS dual-airway internal molding deliver clean lay-up and consistent stiffness, achieving around 335 g at 170 mm while keeping average positive rigidity at 101.5 N/mm. Crank arm lengths run from 150 mm to 175 mm in 2.5 mm steps so riders can match fit, cadence, and leverage.
DUB Axle Carbon Crankset — For SRAM DUB Road Frames
The DUB axle carbon crankset uses the same T1000 carbon architecture on a 28.99 mm SRAM DUB spindle. It shaves weight to about 320 g at 170 mm while maintaining the same stiffness targets and test protocol as the 24 axle version. If your frame is already on a DUB bottom bracket, this crankset is a direct, high-end upgrade with a familiar fit and chainline.
Carbon Crankset Design Philosophy
Engineered Stiffness, Real-World Weight Savings
"A great carbon crankset must balance ultra-low weight with stiffness you can feel out of the saddle. From concept to production we worked with UCI Continental teams and WorldTour riders, refining lay-ups and cross-sections until the carbon crankset delivered race-level response without harshness."
T1000 Carbon and EPS Dual-Airway Molding
"Using T1000 carbon fiber with an EPS dual-airway internal molding process keeps wall thickness precise and eliminates excess resin. The result is a carbon crankset that passes 130 J drop-weight tests and 1800 N cyclic testing at levels around 40% above EN14781, with reliability verified by SGS lab reports."
Carbon Crankset Collection — 24 Axle / DUB Axle
Both carbon cranksets share the same T1000 fiber lay-up, EPS dual-airway internal molding, and UCI-tested structure. The only difference is at the spindle: a 24 mm axle for all 24 mm road bottom brackets, or a DUB axle for SRAM DUB systems. Each package is supplied as a complete carbon crankset ready to install.
24 Axle Carbon Crankset — Complete Road Package with Aero 2x Chainrings.

Full 150–175 mm Length Range
Crank arm lengths from 150 mm to 175 mm in 2.5 mm steps so riders can fine-tune fit and leverage.
T1000 Carbon, EPS Molding
T1000 carbon and EPS dual-airway internal molding deliver low weight and repeatable stiffness from unit to unit.
DUB Axle Carbon Crankset — SRAM DUB-Ready Package with Aero 2x Chainrings.
SRAM DUB Spindle
28.99 mm DUB axle designed for SRAM DUB road bottom brackets and frames.
Around 320 g at 170 mm
Optimized lay-up keeps the DUB axle carbon crankset lighter while matching the stiffness of the 24 axle version.
Same UCI-Level Test Standard
Shares the same test protocol, from lab-verified drop-weight and fatigue tests to on-road feedback from UCI teams.
Why Choose Our Carbon Crankset
Wide Compatibility
Works with modern road drivetrains: the 24 axle carbon crankset fits most 24 mm bottom brackets, while the DUB axle version matches SRAM DUB road standards.
Race-Level Stiffness
Average positive rigidity of 101.5 N/mm and UCI-tested performance give you confident power transfer in sprints and climbs.
Lightweight Construction
Target weights of around 335 g (24 axle, 170 mm) and 320 g (DUB axle, 170 mm) help reduce overall bike weight without sacrificing reliability.
Crank Arm Length Options
Arm lengths from 150 mm to 175 mm in 2.5 mm steps give riders more choice for fit, cadence, and aerodynamics.
Tested and Certified
Each carbon crankset passes 130 J drop-weight tests, fatigue testing around 40% above EN14781, and SGS lab verification before going to market.
Complete Package
Supplied with METARBON AERO 2x chainrings, standard spider, and chainring bolt kit for a clean, integrated look on modern road frames.
Premium Carbon Crankset Package
Each carbon crankset ships as a complete package: crank arms and axle, METARBON AERO 2x chainrings, a standard spider, and a chainring bolt kit. Just match the correct bottom bracket and you have a ready-to-ride carbon crankset upgrade for your road bike.

Frequently Asked Questions
Q: What's the difference between the 24 axle and DUB axle carbon crankset?
A: The 24 axle carbon crankset uses a 24 mm spindle for most 24 mm road bottom brackets, while the DUB axle carbon crankset uses a 28.99 mm SRAM DUB spindle for DUB frames. Both share the same T1000 carbon lay-up, EPS internal molding, and test standard, with the DUB version slightly lighter at around 320 g for 170 mm arms.
Q: Which bottom brackets and drivetrains are compatible?
A: The 24 axle carbon crankset is designed for most 24 mm road bottom brackets, while the DUB axle version is for SRAM DUB road bottom brackets. Both are aimed at modern 11- and 12-speed drivetrains; check your frame and BB standard before ordering.
Q: What crank arm lengths are available?
A: We offer crank arm lengths from 150 mm to 175 mm in 2.5 mm steps, giving riders more choice to match fit, cadence, and discipline—from aero road setups to all-round endurance bikes.
Q: How should I care for and maintain the carbon crankset?
A: Use a torque wrench on all bolts, avoid pedal strikes and chainring rub on the arms, and clean with mild soap and water only. Do not use aggressive solvents or abrasives on the carbon surface, and inspect the crankset regularly for impact damage or deep scratches.
Q: Can I use other chainrings or a power meter?
A: The crankset uses an Easton CINCH-type spider interface, so you can use the supplied METARBON AERO 2x chainrings or compatible CINCH chainrings and some power meter spiders. Always confirm interface and clearance with the manufacturer before installation.
Q: How much does the carbon crankset weigh?
A: The 24 axle carbon crankset targets around 335 g at 170 mm, while the DUB axle version is about 320 g at the same length. Actual system weight will depend on chainrings, spider, and hardware used.
Q: How stiff is it compared with alloy cranks?
A: Lab testing shows average positive rigidity of about 101.5 N/mm, together with drop-weight and fatigue testing significantly above EN14781 requirements. On the road that translates into a solid, direct pedaling feel under sprint and climbing loads.
Q: What testing and certification has the crankset passed?
A: Each carbon crankset passes 130 J drop-weight impact testing, 1800 N multi-cycle fatigue tests at roughly 40% above EN14781, and third-party SGS verification before production. We then validate performance with UCI Continental teams in real racing conditions.
Q: Is this crankset suitable for racing and daily training?
A: Yes. The carbon crankset was developed with feedback from UCI teams specifically for high-intensity use, but its weight and durability also make it a good choice for everyday training and long-distance riding.
Q: What about warranty and returns?
A: Our carbon cranksets are covered by the store’s standard warranty and return policy for manufacturing defects. Please refer to the checkout and policy pages for full details, or contact us with your frame and bottom bracket information before ordering if you have any questions.
