Aenomaly Switchgrade Pro Seat Angle Adjuster
Stated Weight: 145 g (w/o mounting hardware)
MSRP: $245 USD
Intro
I’ve been a big fan of the Aenomaly Switchgrade since reviewing the original version a few years ago. Being able to angle the seat up for very steep descending is great, and my main reason for liking the Switchgrade. Dropping the nose for steep climbs can be nice, too, but the 10° angle change in the nose-down position is more dramatic than I’d prefer a lot of the time. So, when Aenomaly showed a prototype of a more adjustable Switchgrade at Sea Otter 2025, I was quite intrigued. That new variant is here, and it’s called the Switchgrade Pro.
Design
The general concept of the Switchgrade Pro isn’t really any different from the Switchgrade Evo (which is still available as well; the Pro is an addition to the lineup, not a replacement for the Evo). The Switchgrade Pro mounts on top of a wide variety of seatposts that use a two-bolt seat clamp, and allows you to alter the angle of your seat on the fly, using a lever under the nose of the seat.
Both versions of the Switchgrade replace the stock clamp parts and mounting hardware from the seatpost and are compatible with various seatpost models with different shims and hardware kits. The list of compatible posts is too long to list here; see Aenomaly’s website for the details. Both versions are also compatible with standard round seat rails using the stock clamp plates, and alternate versions for oval rails are available separately.
What’s different about the Switchgrade Pro is that it offers a wider range of adjustment, with more settings through the middle of the range. The Switchgrade Evo features three positions with a total of 22° of movement; the Pro bumps that up to eight settings, each separated by 5°, for a total of 35° of movement. Aenomaly calls the fourth position the “flat” / 0° setting (leaving three clicks (15°) of nose up movement, and four clicks (20°) of nose down settings.
You can set the angle of the flat setting as you would on a normal seatpost. There’s probably wiggle room on many combinations of bike / seatpost / seat to shift the adjustment range a bit (e.g., by making the fifth setting flat, so there are four nose-up clicks and three nose-down ones) if you want to.
Some Questions / Things We’re Curious About
(1) How useful does the wider adjustment range and finer adjustability of the Switchgrade Pro feel on trail?
(2) How hard is it to set the Switchgrade Pro to your desired setting while on the move? Dropping the Switchgrade Evo into the middle setting while riding takes a little finesse, so does adding five more settings make that trickier?
(3) Who is going to be best served by the Switchgrade Pro, and what sorts of riders will be better off with the Switchgrade Evo?
Bottom Line (For Now)
The Aenomaly Switchgrade was a genuinely novel product when it first came out, and one that I quickly became a big fan of. I’m quite intrigued by the finer adjustability offered by the new Switchgrade Pro, and will be getting one in for testing soon. Stay tuned.
