CYBREI GP-3 Metarbon carbon crankset

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

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.
