The PRO PLT Seatpost takes the same simple, lightweight, and super secure clamp that is also on the Vibe 7S and builds a slightly heavier, more economical post out of 6061-T6 aluminum. The result is a great, easy to adjust seatpost that drops some serious heft from the price tag.
The PRO PLT Seatpost is anodized black and comes in two sizes -- 27.2 x 280mm and 31.6 x 350mm. As with all PRO posts, all round seat rails, regardless of their material composition, should safely fit in the PLT post. The clamp offset is 20mm, which is in the range of what most traditional setback seatposts offer. Please Note: The clamp design will not work with oversize, oval shaped carbon rails.
