CYBREI 1x aerodynamic crankset

Cybrei Carbon Aero Stone 1x Crankset

This crankset pairs the low weight of Cybrei carbon crank arms with the aerodynamics of a solid Stone 7075-T651 CNC-machined aluminum chainring. Engineered to resist deformation under heavy pedaling loads, its narrow-wide alternating tooth profile keeps the chain aligned on the cassette without requiring a chain guide—whether taking repeated hits in gravel racing, running a 1x setup on the road, or transferring power through big gears in time trials.

Key Features

T1000 Carbon and 7075-T651 Alu Alliance: High-density carbon crank arms coupled with a 0.03 mm CNC-machined chainring to eliminate flex during hard sprints.

Narrow-Wide Profile: Alternating wide/narrow teeth holding the chain securely on rough sections and eliminating chain drop.

38T to 58T Chainring Range: A broad range of options to configure agile gearing for gravel (38T-44T), smooth alignment for road (46T-50T), or maximum gearing for time trial and track (52T-58T).

29 mm SRAM DUB or 24 mm Shimano Spindle: Stiff spindles guaranteeing direct compatibility with most bottom brackets on the market.

Compatibility

This crankset installs on bottom brackets matching SRAM DUB (29 mm spindle diameter) or Shimano (24 mm) standards. The Easton Cinch Direct Mount chainring works with 9, 10, 11, and 12-speed MTB chains, as well as 9 to 12-speed Shimano road chains and 9 to 11-speed SRAM road chains. This crankset is not compatible with SRAM AXS 12-speed and 13-speed Flattop flat-backed chains.

During assembly, apply neutral grease to the spindle and Cinch chainring splines, then torque the self-extractor to the manufacturer's specified torque rating. Need advice on choosing crank arm length or tooth count? Write to us.
