Aenomaly Constructs SwitchGrade Pro Seat Angle Device

BC-based Aenomaly Constructs has been producing their SwitchGrade saddle angle adjusters for five years now. We were always intrigued by the concept, and we found a lot to like when we first got to test it in 2023. The version that was available then was based around three fixed steps of adjustment, that turned out to be angled a bit too far apart for our liking. Aenomaly heard that criticism (not only from us), and have reacted accordingly – with the introduction of the Pro version in 2025, they added a degree of configurability that should allow the device to match up with all kinds of terrain profiles and rider preferences. Here’s our report after a couple of months on the trail.

Initial Impressions

The original SwitchGrade was constructed with “winch-and-plummet” type riding in mind, the kind that you do a lot of in BC for example. Built for steep climbs and steep descents, it offered three riding positions separated by 22 degrees in total – a 0-degree middle position, a 10-degree forward tilt position for climbing, and a 12-degree rearward tilt for descending. The issue with these settings is that they need to match the terrain, and if you typically ride more mellow and/or undulating climbs, the 10 degrees of forward tilt is too much. When we tested the original, we suggested that maybe making several versions with different amounts of tilt was the way to address this, but Aenomaly went one better – the Pro version offers up to 35 degrees of total angle adjustment, separated in 8 steps with 5 degrees between each step.

You can place the saddle in any of the available 8 positions, but you can also limit the total adjustment range by placing 2 small bolts in different holes inside the mechanism. Using these bolts, you can configure the SwitchGrade Pro to suit your needs precisely. Starting at the extreme, you could leave just two positions available, separated by 5 degrees of tilt. Add one more step, and you’re looking at -5, 0, and 5. You can add steps on either side of neutral within the total limit of the 8 available. If you add 2 steps to either side for example, you end up with a total of 5 available positions to chose from out on the trail. Moving between the steps is as easy as grabbing the lever, tilting the saddle and releasing it in the desired position.

SwitchGrades have always been well made, and the Pro is no exception. The machining is pleasing, and the finish is of high quality. The construction is clever, and manages to provide solutions for a multitude of common dropper posts without adding too much stack height – on average, count on adding about 10 mm to your stack, so make sure you have room in the seat tube for it. The installation is relatively straightforward, although some trial and error may be required to find the correct angles, and some of the operations are a bit fiddly. It’s a one-and-done kind of deal though, so nothing too worrisome.

On The Trail

We tested the SwitchGrade Pro with a couple of different saddles. Aenomaly specifically states that you need a certain minimum of free space between the saddle base and the top of the SwitchGrade, but we broke that rule with an SQlab saddle and we suffered no real adverse effects. The base of the saddle contacts the lever when you operate it, but that just adds a bit of resistance to the system. Of course, this saddle also flexes a bit and contacts the SwitchGrade at full compression, which may not be awesome over time but it has not caused any actual issues in testing so far.

We started out setting the system up with 3 steps, and positioned the saddle for optimum comfort on flat ground in the middle step. That gave us 5 degrees of tilt to use in either direction, -5 for the climbs and +5 for the descents. It does not sound like a lot, but it actually makes a pretty big different in real life already. Since we were testing on non e-bikes, the 5 degrees of forward tilt matches our climbs really well, providing that extra support without pushing you too far over the bars. We also like being able to leave the saddle tilting forward in undulating terrain, which is a lot less comfortable if you opt for 10 degrees or even more. Of course, nothing stops you from adding a couple of climbing steps and then choosing between them accordingly, but since the adjustment involves taking your hand off the bars and hunting for the right step, it's not something we found ourselves wanting to do every 30 seconds.

Similarly, 5 degrees of rearward tilt opens up a bit more space around the back of the saddle, pretty much like adding a bit of travel to your dropper post. You can add steps if you want to really achieve that DH-like saddle angle for when the fun really begins, which can add upwards of 30 to 40 millimeters of extra clearance depending on where you clamp your saddle rails.

So what’s the verdict then? Well, we asked for these changes when we tested the original SwitchGrade, and we’re not disappointed with the results. The device is still as easy to use on the trail, although if you set it up with more than 3 steps of total range you may be “hunting” a bit for the desired position in action, as there are no hard stops positioned at the intermediate steps. The lever never hangs up though, it will always find its way into the closest position, so there’s nothing clunky about it – it just takes some practice to always nail the desired position in one go. But that’s a price we’re more than willing to pay to have the perfect saddle angle available for all kinds of climbs and descents. As for durability, the SwitchGrade Pro is a solid piece of kit that should be up for its fair share of abuse. We ran a sample of the previous generation for quite a few months without noticing any performance degradation, the stops were still crisp and clean and the clamps held the rails securely without slipping or letting the seat angle change. We'd expect more of the same from the Pro version (which we've now been testing for 3 months).

What’s The Bottom Line?

The SwitchGrade always had a lot of potential, with a solid design that works really well in action – IF the angles on offer matched your terrain and riding style/fitness/e-bike use. With the new Pro version, it’s now easier than ever to get the angles exactly right for YOUR needs, and with that we feel like the design finally delivers on its promise. Definitely consider one of you regularly tackle fairly long climbs and/or like the feel of a rearward tilted saddle for descending.

Johan loves bikes, which strangely doesn’t make him any better at riding them. After many years spent practicing falling off cliffs with his snowboard, he took up mountain biking in 2005. Ever since, he’s mostly been riding bikes with too much suspension travel to cover up his many flaws as a rider. His 200-pound body weight coupled with unique skill for poor line choice and clumsy landings make him an expert on durability - if parts survive Johan, they’re pretty much okay for anybody. Johan rides flat pedals with a riding style that he describes as "none" (when in actuality he rips!). Having found most trail features to be not to his liking, Johan uses much of his spare time building his own. Johan’s other accomplishments include surviving this far and helping keep the Vital Media Machine’s stoke dial firmly on 11.
