Tailfin Cycling S One & X One Rack Review

There are two mounting options, Axle + Fast Release Dropouts or Frame Mounting. We chose Axle + Fast Release Dropouts for this review.

The Carbon Top Stay, which also works with the X One Rack

“Ingenious fast-release dropouts make it simple for you to use one rack for all of your bikes or one bike for everything.”

Tailfin Cycling Quick Release

“The Frame Mount Adaptor set allows you to mount directly to your frame mounts but still keep the Fast Release Dropouts for easy on and off rack mounting.” – This also applies to the X Series rack, below.

Tailfin Axle Mounting System (TAMS)

Replace your axle with a Tailfin axle to mount the Tailfin rack. Most bicycles use a quick-release axle, however, we also support the new Thru Axle standards (e.g. 12×142, 12×148, E-Thru, Syntace X-12, etc). This system also applies to the X Series rack, below. Tailfin has further information available about TAMS, here.
