Cannondale Internal Seat Post Wedge - 25.4mm
Cannondale Synapse Seatpost Cover - KP301
Help. I can't figure out how to adjust my seat post! Attached is a picture of said seat post. If it matters it's a 2018 cannondale synapse carbon 105. Thanks ahead of time and feel free to call me an idiot or something along those lines. : r/bicycletouring
