Fair Wheel Bikes E-One Seatpost

The E-One is designed specifically for frames with a 27.2 mm seat tube diameter. Please verify your frame's seatpost size before purchasing, as this is a standard size for many performance road, gravel, and cyclocross bikes but will not fit frames requiring other diameters.

Yes, the universal clamp head is designed to accommodate a wide range of rail types, including standard 7x7 mm metal rails and oversized 7x9 mm or 7x10 mm carbon rails.

The 350 mm version weighs approximately 129 grams, while the 400 mm version weighs approximately 145 grams. Both options offer an exceptionally low weight profile for their respective lengths.
