The CYBREI carbon crankset is a lightweight, stiff Chinese crank built around the Easton Cinch interface, available with a 29 mm alloy DUB axle or a 24 mm titanium axle, and praised for its low weight, stiffness even for heavy riders, and compatibility with Cinch spider power meters. Owners and reviewers agree it is a strong value for weight-conscious builds and is used at World Tour level, but note a wider Q-factor than Shimano, fiddly installation, and mixed experiences with Cybrei's own carbon chainrings.
Pros
- Very light: about 320–335 g for the arms, and a complete setup with power meter and rings weighed 530 g versus 580 g for SRAM Red E1 power.12
- Good stiffness for the weight, with riders over 80 kg reporting no flex issues.13
- Cinch interface accepts a wide range of spider power meters (Xcadey, Sigeyi, Power2Max Easton version) and aftermarket spiders such as Stone's aero spider.12
- 24 mm titanium version offers a straight swap for Shimano setups and uses larger bearings than DUB.2
- Shifting with Shimano 110 BCD chainrings works well on the Cybrei or Elilee spider.1
- Single centre bolt makes removal and reinstallation quicker than a Shimano crank; a titanium-spindle set showed no galling after a year with copper grease.1
- Popular and reliable with few reported failures, used by SRM and in the World Tour.2
- Good customer support via PandaPodium.1
Cons
- Flat arms and a wider Q-factor than Shimano mean heels-in riders may rub and need to move cleats.1
- Preload adjuster bolt can shear.1
- Spider lockring is fiddly to install and crank removal can be very tight.1
- Chainline may need spacers or bottom bracket changes on some frames.1
- Cybrei's own carbon chainrings can be noisy or delaminate under high power; many prefer Shimano or Carbon-Ti rings.1
- 24 mm spindle version is $70 more expensive and 15 g heavier than the DUB version.2
- 30 mm spindle may lead to faster bearing wear, and DUB bearings are considered too small for some bottom bracket standards.32
- Price considered high at $499 and not the cheapest option available.32
Key Facts
- Arms weigh about 320 g with the 29 mm DUB alloy axle and about 335 g with the 24 mm titanium axle; a complete build with Xcadey power meter and Carbon-Ti rings weighed 530 g versus 580 g for a SRAM Red E1 power crank.12
- Q-factor is 148 mm and 2x chainline is 44 mm; available lengths are 162.5, 165, 167.5, 170, 172.5 and 175 mm.1
- Uses the Easton Cinch interface with a 40 g alloy 4-arm spider; compatible with Xcadey, Sigeyi and Power2Max Easton-version spider power meters, and Elilee sells a Dura-Ace-pattern spider for Shimano rings.12
- Two spindle options: a 29 mm alloy DUB axle and a 24 mm titanium axle that fits Shimano 24 mm bottom brackets; the 24 mm version is about 15 g heavier and $70 more expensive.12
- Main bolt torque is 50 Nm and the spider lockring requires a BBT-22-style tool.1
- Cybrei carbon chainrings weigh 127 g (50/34), 134 g (52/36) and 141 g (54/38); alloy rings weigh 148 g, 156 g and 164 g.1
- A Cybrei Ultra version with a carbon spindle, claimed 270 g and 150 mm Q-factor, launched in September 2026 in lengths 155–172.5 mm.1
- 160 g lighter than Shimano Ultegra cranks and about 150 g lighter than a Shimano Dura-Ace R9200P setup.32
Reviews & Ratings
10:01The reviewer discusses the CYBREI Carbon Crankset, comparing the original DUB version with the new 24mm spindle version. He highlights the crankset's popularity, stiffness, lightness, and reliability, noting its adoption by SRM and use in the World Tour. The 24mm version offers compatibility with Shimano setups and larger bearings but is heavier and more expensive due to its titanium spindle.
34:14The reviewer mentions the CYBREI Carbon Crank Assembly w/ Xcadey Powermeter Spider as part of their lightweight gravel bike build. They highlight its use in multiple bikes and its compatibility with their build goals. The crank set is paired with a 38-tooth chainring from Stone for better climbing performance.
14:50The CYBREI Carbon Crank Assembly w/ Alloy Spider is not mentioned in this video.
55:19The reviewer discusses the CYBREI Carbon Crank Assembly w/ Alloy Spider, highlighting its lightweight design and stiffness, but notes potential concerns about bearing longevity due to the 30mm spindle.
The CYBREI carbon crankset is a light Chinese crank with an Easton Cinch interface, sold with a 40 g alloy 4-arm spider and either a 29 mm alloy DUB axle (about 320 g arms) or a 24 mm titanium axle (about 335 g). Lengths run from 162.5 to 175 mm; the Q-factor is 148 mm and the 2x chainline 44 mm. Owners praise the low weight, good stiffness even for 80+ kg riders and the fit with Cinch spider power meters such as Xcadey, Sigeyi and Power2Max's Easton version. A Cybrei build with an Xcadey meter and Carbon-Ti rings weighed 530 g, against 580 g for a SRAM Red E1 power crank. The single centre bolt makes removal quicker than a Shimano crank. A titanium-spindle set came apart cleanly after a year with its copper grease, with no galling. Downsides: - the arms are flatter and the Q-factor wider than Shimano's, so heels-in riders may rub; - a preload bolt sheared; - the spider lockring is fiddly and removal can be tight; - some frames need chainline spacers; - Cybrei's carbon chainrings can be noisy or delaminate under high power. Shimano 110 BCD rings shift well on the Cybrei or Elilee spider, and Stone makes an aero spider. A Cybrei Ultra with a carbon spindle (claimed 270 g, 150 mm Q-factor) launched in September 2026.
