CYBREI GP-3 Metarbon Carbon Crankset

There are stock components, and then there are standards of high engineering. The CYBREI GP-3 has established itself as the most sought-after carbon crankset, validated by the most demanding cyclists and ridden at the pinnacle of the World Tour by riders like Tadej Pogacar himself. Its philosophy is strict: eliminate the unnecessary to maximize power transfer, without ever compromising structural integrity. The assembly of 320g T1000 carbon crank arms and a CNC-machined aluminum spider weighing just 40g results in an ultra-light double chainring setup, for a total weight of 495 grams (DUB version, 50T).

This level of lightness is accompanied by clinical validation. The structure is certified by SGS-type tests, a 130 J drop test, and a fatigue protocol exceeding the EN14781 standard (1800 N). At CYKL, the premier official European distributor, we apply the manufacturer's warranty to this high-performance component, available in 8 crank arm lengths for a perfect biomechanical fit.

Key Features

The ultra-light benchmark: Crank arms weighing 320g, hybrid HM Carbon/Alu chainrings at 135g, and a minimalist 40g CNC spider. One of the lightest double chainring setups in the peloton.

Power transfer and reliability: The dual-channel EPS internal molding process ensures optimal carbon density. Result: a structural stiffness measured at 101.5 N/mm, validated by intensive testing protocols (SGS, 130 J drop test).

Optimized mechanical interface: The 40g spider ensures a flawless anchor for the chainrings. The construction of the Metarbon Aero chainring (HM Carbon + CNC 7075-T6 Alu) guarantees crisp shifting and impeccable chain retention under load.

The CYKL service: By ordering from the number one CYBREI distributor in Europe, you secure your build through our expertise and tailored support.

Compatibility and standards

It is recommended that you apply lithium grease between the chainrings.

This crankset integrates natively with 11 or 12-speed road and gravel drivetrains. The mounting interface uses an Easton-type base, paired with a 110x4 BCD spider (Shimano pattern). You have three chainring gearing options (50-34T, 52-36T, 54-38T) and a choice between the two major axle diameters: SRAM DUB (28.99 mm) or Shimano (24 mm).

The crankset respects modern standards with a 44.5 mm chainline and a 148 mm Q-factor. Before ordering, verify your bottom bracket standard. For your maintenance operations, we recommend using a CYBREI crank puller with the ISIS standard. In doubt about your setup? Our workshop is at your disposal.

Ultra-light crankset

Engineered from T1000 carbon using an EPS internal molding process, the crank arm structure weighs only 320g (DUB version). Combined with Metarbon Aero chainrings (135g) and the measurement spider (100g), the complete assembly reaches a final weight of 555g. This extreme lightness is matched by 101.5 N/mm stiffness and an optimized aerodynamic profile to eliminate friction and power loss.
