PRO Vibe Seatpost Sideclamp Di2

PRO makes some excellent seatposts for road and mountain use, and the Di2 battery ready Vibe Seatpost Sideclamp may be the best of them. Built in a one-piece layup using T800 unidirectional carbon fiber, the post is light, laterally stiff, vertically compliant, and ready for action. The innovative single-bolt clamping mechanism fully secures your round saddle rails without damage (comes with oversized oval rail clamp as well), and takes up minimal rail length, allowing you full range of rail and angle adjustment. The matte UD finish features a simple, glossy PRO logo to add just a little bit contrast that makes the post appealing to any rider.

Featured in a 400mm length, the Vibe Sideclamp Di2 was fully prepped to handle the svelte Di2 seatpost battery with dual flat sections inside the cylinder to hold the battery. PRO made no concessions, with machined aluminum side clamps, composite inner rail wedges for rail safety, and titanium hardware. The single-bolt design is easy to use, and you have tremendous range of angle for saddle set-up. The single-bolt has a significant torque spec of 13Nm, so please use a torque wrench for proper installation. Of course PRO marks the post with the standard height indicator for precise, repeatable use.

Full carbon posts without Di2-ready features usually weight in around 200 grams for a 27.2x400mm, so you will be glad to know the preparation adds only 14 grams, bringing this size in at 214 grams. You won't find a higher quality, better finished seatpost with Di2 battery compatibility at this weight. You can trust PRO, and their parent company Shimano to design and execute the best Di2 compatible seatpost available.
