RIDEA - LamiFlow R491 chainrings BCD110 四爪 氣動齒片

LamiFlow R491 unique design creates a laminar flow to reduce drag, with the air passing through the interior and exterior of the chainring, helping you to keep your momentum, while retaining the legendary stiffness of RIDEA chainrings.

LamiFlow R491 is available for 2x and 1x setups. Double chainrings are designed with multiple chain bridges to maximize front derailleur performance, while single chainrings use the exclusive X-ODON technology to prevent chain sucks and to increase the stability of the chain.

Inset versions move chainline 3 mm inwards.

R491 chainrings are compatible with all RIDEA R491 cranksets, also SPM2-R4, and Shimano cranks with BCD of 110 mm.
