Fizik Terra Argo X3 is an off-road race saddle crafted for stability, comfort, and responsiveness on rugged and dirty rides and is aimed at racing. It delivers what it promises and, although it’s not the lightest around, it offers good support and stability, while providing room to shift your weight around, too.

The Fizik Terra Argo X3 is Fizik’s most recent, off-road racing-specific saddle designed for comfort and performance. It’s different from the more gravel-oriented Terra Argo lineup that first launched in 2020 and is a low-profile saddle with smooth contours that aid easy adjustment of position.  

The Argo X has a slightly wider nose, which should provide more support to help riders hold their grip during steep climbs and act as an optimal base from which to produce power without sacrificing comfort.

Like many modern saddles, there is a pressure relief channel in the middle of the saddle and, instead of a proper cutout, there is a rubber layer at the bottom of it functioning as a mud flap, blocking unwanted dirt and spray from unpaved roads.

The X3 model we tested sits in the middle of the three-tier range and features Kium hollow rails. Fizik says the saddle weighs  231g – mine tipped the scales at 236g.

I have been testing the Vento Argo X3 on the Canyon Grail 8 CFX for the past few months. Although I was initially unsure of the saddle’s suitability for my riding, I was quite pleased with its secure feel and comfortably completed over four-hour rides on it without issues. And having tested this saddle on gravel, I think it could be even better for a mountain bike rider.

This saddle deviates from Fizik’s Terra Argo gravel saddle quite noticeably with smoother contours and a longer nose –although Fizik says this saddle is 5mm shorter than the Terra. The nose is also wider (something I don’t quite like) but can see working well for mountain bike riding when you need to use the saddle for stability during descending.

The overall profile is flat, which works well if you like to shift around on the saddle. The cutout, which doesn’t extend to the nose, is generous but the way it is shaped means it can easily dig into sensitive areas. This remains the one gripe that prevents me from switching to a Fizik saddle on my bike. Being a race saddle, this one is quite solid and, unless you get it set up well, it’s easy to have some discomfort. I was able to complete multi-hour rides on this but I would like the cutout to be less ‘angular’ if I were to use it for a 200km gravel race. 

Setting it up was an easy task – it has plenty of rail length for adjusting the fore-aft as well and, unlike the Terra, has a rather standard 43 mm stack height. I installed it with the nose tilted slightly down as I simply felt it was pressing into the soft tissue too much (especially if I was riding on the drops). With a couple-degree tilt, however, I found the saddle a lot more comfy.

The cutout’s mudflap is effective at preventing dirt from getting to your crotch and if any moisture builds up, there is a drain hole so you won’t have a pool of puddle water sloshing on the saddle. This is a nice touch for an off-road saddle.

Overall, the ride feel on this saddle is comfortable – the upper material is neither slippery nor sticky and I felt it was easy to both stay put but also move around when needed. The actual seating area is quite large at the back, and it’s also easy to sit further forward on the saddle because of the wider nose. 

There are only two widths available for this saddle, 140mm (tested) and 150mm and that might be an issue for some, but I found the 140mm offered me a good planted feel.

Fizik Vento Argo X3 gravel saddle – Verdict

Overall, the Fizik Terra Argo X3 is a great saddle for any off-road racer – it offers adequate support, it’s relatively lightweight and it has a good pressure relief channel. The flat shape allows shifting weight around and means you’ll have support for pedalling even if you have to at times sit further back or forward. 

Looking at the best gravel bike saddles, the Argo X3 goes up against some stiff competition. Starting with the price, at £145 the Argo X3 is competitively priced compared to the Repente Artax GLM (£165) and Ergon SR Allroad Core Comp (£125). However, the Specialized Phenom Expert with Mimic​ which I tested recently retails for less at £115 and also features the Mimic technology which I find very comfortable for the female anatomy. The Repente doesn’t have a covered pressure relief channel like the Romin and Ergon SR but it is extremely lightweight at 164g. 

Overall, the Fizik Argo X3 is a great option for off-road racers. It’s comfy on even longer rides and especially well-suited for when you want to be able to freely move around the saddle. It’s neither the lightest nor the cheapest around but its neutral shape will find favour with most riders.
