Single-bolt saddle clamps make angle adjustments significantly easier than traditional two-bolt designs, and PRO's Vibe Alloy Seatpost uses this system to let you dial in saddle tilt without fighting a second bolt that wants to move every time you loosen the first one. The clamp head secures 7mm round saddle rails and allows rotation while snugged down, so you can fine-tune your position without starting over from scratch each time.

The post itself is 3D forged from AL-2014 aluminum alloy, which produces a laterally stiff structure with enough vertical compliance to take the edge off road vibration. That forging process creates a more consistent grain structure than extruded aluminum, improving durability and allowing PRO to keep the weight competitive with the construction method. The matte black anodized finish resists scratches and works visually with just about any frame color.

If you're running Shimano Di2, the hollow post interior accommodates an internal battery, keeping your cockpit clean and freeing up space elsewhere on the bike. The 350mm length provides plenty of adjustment range for most frame sizes, and the 20mm setback positions the saddle behind the seatpost centerline for riders who need their weight shifted rearward to achieve a neutral pedaling position. This offset works well for riders with longer femurs or those on frames with steep seat tube angles who need help getting their knee over the pedal spindle.... Read More
