The Argon 18 ASP-4500 seatpost is designed for use with the Argon 18 Electron Pro track bike.

The ASP-4500 is a two-way seatpost that can be flipped to achieve either a road or time trial position - seat angles of 75 and 78 degrees are achievable to ensure you get the best fit for your event. The seat clamp offset can be set by flipping the rail clamp and the rocker, resulting in road positions of -10mm to -15mm and TT/tri positions of +10mm to 15mm.

Constructed from carbon fibre, the ASP-4500 is extremely aero whilst retaining reliability and strength. Replace your Electron Pro seatpost with a genuine Argon 18 ASP-4500 seatpost.
