SwitchGrade EVO Seat Angle Adjuster - Pack B

The Aenomaly Constructs SwitchGrade EVO Seat Angle Adjuster – Pack B is for riders who demand precision, adaptability, and comfort on every climb and descent. Designed to transform saddle dynamics with a simple flick of a lever, it gives total control over saddle angle and position—whether grinding uphill or charging down technical lines.

Building on the original SwitchGrade design, the EVO refines the concept with a sleeker, more integrated profile and expanded compatibility. Its interchangeable snap-fit shims make it futureproof for evolving seatpost designs, while its CNC-machined aluminum construction ensures the kind of durability that serious riders expect.

• On-the-fly adjustability: Instantly change saddle tilt for optimized climbing or descending efficiency.
• Compact and integrated: 17% smaller than the V1 for a cleaner, more streamlined look.
• Customizable setup: Easily switch between 2 or 3 locked positions to match riding style and terrain.
• Precision geometry shifts: Climb mode steepens by -10° for better power transfer; descend mode tilts 12° back for improved control and comfort.
• Versatile compatibility: Works with a wide range of dropper and rigid seatposts and supports both round (7x7) and oval (7x9, 7x10) saddle rails.
• Adjustable lever orientation: Run the release lever forward or backward to suit personal preference.
• Premium build: CNC machined in Canada from 7075-T6 and 6061-T6 aluminum for lightweight strength and precision fit.

At just about 85 grams net weight gain over stock clamps, the SwitchGrade EVO delivers a massive upgrade in comfort, performance, and bike fit versatility without adding unnecessary bulk. For endurance riders, technical trail chargers, or anyone battling lower back or hip discomfort, this is a simple yet transformative upgrade that redefines how the saddle works for you.
