Zero25 is a lightweight, universal seatpost with a twist: it's two seatposts in one. The two clever, reversible saddle rail clamps transform the post from zero saddle setback to 25 mm setback. All that's needed is to flip the clamps from one side of the seatpost head to the other and the offset changes.

No more problems with getting the wrong seatpost or needing another one when you change the type of saddle you use – it now takes 30 seconds to transform your seatpost. And the best news is that despite the double functionality, the Zero25 is even lighter than the previous seatpost.

Zero25 can handle any type of seatpost rails, from round to all oval shaped carbon rails.

Zero25 Pro has an alloy pillar and comes in two diameters, 27.2mm and 31.6mm, and one length, 350mm.
