Abstract
A seat angle adjustment device includes a seat tube, a lower clamp, an upper clamp, two nuts, and two bolts. The top end of the seat tube has two through holes and a convex curved surface. The lower clamp has two lower clamping grooves and a concave curved surface abutted against the convex curved surface of the seat tube. The upper clamp has two upper clamping grooves. Two saddle rail clamping grooves are formed between the upper and lower clamping grooves, and each have a position lower than the vertex of the convex curved surface of the seat tube. The nuts and the bolts are screwed to each other. One of them are disposed to the upper clamp and the other of them are disposed in the through holes. Thus, the present invention allows the lifting stroke of a seat to be increased when used with a liftable seatpost.
