Wilier Filante SLR ID1 Black Carbon Seatpost -15mm Offset

There's a moment, in the final kilometers of a race, when every gram and every watt counts. The Wilier Filante SLR ID1 carbon seatpost was born for that exact moment — not as an afterthought, but as an integral part of the bike's design from day one.

This isn't an aftermarket component adapted to fit. It's the seatpost Wilier's own engineers drew alongside the frame, shaped to disappear into the tube profile so completely that the eye can't find where frame ends and post begins. That's what factory integration really means: aerodynamics that were never compromised, and a silhouette that stays true to the Filante's race pedigree.

Underneath the aero shell is a carbon layup built for people who race, not just people who ride fast on weekends. Stiff enough to put every ounce of your effort straight into forward motion, tuned enough to keep you comfortable through a long breakaway.

This specific version carries a -15 mm offset, pulling the saddle back for riders who want a classic position over the bottom bracket — the setup serious bike fitters reach for when your pedaling mechanics call for it.
