The Ratio Tailfin Bolt Allows for Rack Attachment

Ratio Technology has unveiled a specialized bolt designed to facilitate the attachment of Tailfin racks to bikes equipped with their direct-mount Ratio Mech. This new component is specifically for bikes utilizing a Universal Derailleur Hanger (UDH) and comes with a Hex reducer, addressing a niche compatibility issue for cyclists wishing to integrate a Tailfin system with Ratio’s innovative drivetrain solution.

This development speaks to the ongoing evolution of bike component integration, particularly in the burgeoning gravel and bikepacking segments where rack compatibility is paramount. Ratio’s direct-mount Mech, compatible with both UDH and standard hangers, already offers a streamlined aesthetic and improved shifting. However, the unique mounting of direct-mount derailleurs often creates conflicts with through-axle rack systems like Tailfin, forcing riders to choose between performance and utility. This small bolt bridges that gap, acknowledging a specific demand from a growing segment of riders.

Ultimately, this is a pragmatic solution to a very modern problem. In a world where component integration often feels like an afterthought, Ratio’s proactive approach to rack compatibility is a welcome, if highly specific, nod to practical utility.
