The Wheeltop CR20 is a lightweight carbon road crankset built around a precision-machined 24 mm titanium spindle. Its UD carbon crank arms, standard 110 BCD chainring interface and eight-bolt spider interface provide a practical foundation for a modern road drivetrain.
UD carbon crank arms
The crank arms use unidirectional carbon-fibre construction, combining low weight with the strength required for regular road riding and racing. A restrained finish gives the CR20 a clean appearance that works across a wide range of road-bike builds.
24 mm titanium spindle
The CR20 is fitted with a 24 mm titanium spindle, offering a useful balance of low weight, strength and corrosion resistance. Its 24 mm diameter is compatible with commonly available road bottom-bracket systems designed for this spindle standard.
One Piece Spider-Ring
Light weight 8-bolt direct mount one piece spider-ring available in 50-34t & 52-36t. A standard 110x4 spider and individual chainrings are available for customisation.
Power-meter compatible
An standard 8-bolt direct mount spider interface allows the CR20 to be paired with compatible eight-bolt spider-based power meters, providing a straightforward option for riders who want to add power measurement to their drivetrain.
