SwitchGrade EVO Seat Angle Adjuster - Pack A

The Aenomaly Constructs SwitchGrade EVO Seat Angle Adjuster - Pack A redefines saddle positioning with precision engineering and trail-tested functionality. Designed for riders who demand control, comfort, and versatility, the EVO gives you the freedom to instantly adjust your saddle angle for climbs, descents, and everything in between — no tools, no guesswork, just performance on demand.

This latest SwitchGrade EVO version is 17% smaller than the original, creating a sleeker, more integrated look that pairs cleanly with modern seatposts. Interchangeable snap-fit shims expand compatibility across a wider range of posts, futureproofing your setup for years of riding ahead. Whether dialing in climbing efficiency or descending confidence, the EVO’s on-the-fly adjustability transforms how your bike feels on every section of trail.

• On-the-fly saddle angle control – instantly switch between climb, neutral, and descent positions for optimized body position and power transfer.
• Customizable 2- or 3-position setup – easily block one detent for simplified operation.
• Climb mode steepens effective seat angle by -10°, adds about 20mm height and 10mm forward offset for efficient pedaling on steep grades.
• Descent mode tilts 12° back, lowering saddle height by roughly 30mm for aggressive downhill control.
• Reversible release lever – run it forward or backward depending on personal preference and frame layout.
• Precision CNC construction from 7075-T6 and 6061-T6 aluminum, built in Canada for lasting durability and strength.
• Compression wedge rail clamps ensure compatibility with 7x7 round rails and oval rails (7x9, 7x10). Oval rail clamps sold separately.
• Lightweight design adds only about 85g over stock rail clamps.

The SwitchGrade EVO isn’t just about performance — it’s about comfort. Riders dealing with back or groin discomfort will appreciate the ability to fine-tune saddle tilt to relieve pressure points on long rides. For anyone chasing the perfect fit and feel from their bike, this adjuster delivers a truly custom experience every ride.
