Pro Stealth Evo carbon seatpost
The PRO Stealth Evo seatpost is Shimano's high-end carbon seatpost. In order to save every gram possible, the Stealth Evo takes a unique approach to the saddle clamp mechanism. Instead of the clamp boltin vertically to the post, it bolts down horizontally, clamping to the side of the seatpost. Because of this, the clamp actually grabs the saddle rails more evenly; instead of simply putting pressure vertically (top and bottom) on the rails, the PRO Stealth Evo clamps from the top, bottom, and inside the rail. This makes your saddle that much more secure.
