Carbon seatposts at this weight class require compromises somewhere—either the clamp mechanism adds grams back, the diameter options are limited, or the setback doesn't match your fit requirements. The Ritchey SuperLogic Carbon Seatpost addresses each of these constraints through a one-piece carbon construction that integrates the rail clamp directly into the post structure, eliminating the separate hardware that typically accounts for a significant portion of seatpost weight. The result is a post that weighs under 130 grams in the 27.2mm diameter while maintaining the clamping security and adjustment range that proper bike fitting demands.

The single-bolt clamp design uses a WCS alloy head that grips both saddle rails simultaneously, allowing micro-adjustments to saddle angle without the trial-and-error of two-bolt systems. Twenty-five millimeters of setback positions the saddle behind the post centerline, which suits riders who need their saddle further back relative to the bottom bracket—a common requirement for longer femurs or time trial positioning adapted to road geometry. The clamp accommodates 7x7mm and 7x9mm oval rails, covering the majority of performance saddles currently on the market.

Ritchey offers the SuperLogic in six diameter options: 27.2mm, 30.9mm, 31.6mm, and 34.9mm cover the most common frame specifications, while 26.8mm and 31.8mm address older Italian frames and specific Trek models respectively. All versions maintain 350mm of overall length and the same 25mm setback, so the weight and fit characteristics remain consistent regardless of which diameter your frame requires.... Read More
