To be completely honest, there are some bikes where we require a zero-offset post and some bikes where a bit of an offset is required depending on the seat tube angle or the size frame we're going with. That's why the Zero 25 LTD Stealth Seatpost from 3T is so awesome. Whether you're switching over to a new bike or just trying to dial in the fit, it brings its elegant Italian style and design into a highly functional seatpost. The Zero 25 LDT offers both a zero and 25mm offset in the same post with a sleek design with maximum versatility. This allows you to experiment with different saddle positions or easily dial in the fit if you change saddles with different lengths. The secret of the Zero 25 LTD is at its head. By easily swapping the left and right, internal and external cups, you can achieve either a zero offset in one position or have a 25mm offset in the other. Either way, you're treated to a lightweight carbon post with stainless steel hardware that works with virtually any saddle rail material.
