Simple et rapide
Twin bolt angle adjustment on a reasonably stiff post. The anodised finish is nice, and the logo is cool!
All simple and immediate as always but pay attention to the item description: the seatpost measuring 400mm in total not 400mm of pipe (without clamp).In any case, so also it goes well!
