LamiFlow R5ST 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 R5ST is available for double and single ring 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 increase the stability of the chain.
LamiFlow R5ST chainrings are compatible with Ridea cranksets with BCD130 (R5ST, ITST, ITFT), Ridea cranksets for folding bikes, as well as with other manufacturer cranksets following the standard BCD130.
