SwitchGrade EVO Seat Angle Adjuster - Pack D

Aenomaly Constructs SwitchGrade EVO Seat Angle Adjuster - Pack D takes saddle optimization to the next level, giving riders precision control over seat angle and position with the flick of a lever. Designed for serious trail riders, enduro racers, and anyone chasing all-day comfort, the SwitchGrade EVO transforms how your bike fits and performs on climbs, descents, and everything in between.

Building on the proven original, the EVO is 17% smaller for a sleeker, more integrated look while adding interchangeable snap-fit shims for even broader seatpost compatibility—ensuring it stays relevant as your bike evolves. Whether dialing in a steeper angle for efficient climbing or dropping the saddle back for aggressive descending, this adjuster makes it fast, intuitive, and rock-solid.
