It's a common misconception that aero road bikes are only for the fastest sprinters on race day. They've also got a reputation for being harsh and bad climbers. For the most part, all of those beliefs people hold onto are relics of history. If you look at our list of the best aero road bikes you can see the wide range of options and read about those that are great climbers and have plenty of compliance. Many of them are still designed around race day though but there is another good reason to choose an aero road bike.

For those that prioritise long days and long adventures, an aero bike means a little less work. The Ventum NS1 comes from a direct-to-consumer brand that started with a triathlon bike - a small group of passionate people who like to ride bikes and like to do it fast. The marketing touts it as ready for long days and also race days so we spent time assessing these claims in detail.

The Ventum NS1 is available in three matte colour options and a fourth that costs a bit extra. The base level offers a soft, matte finish that is nice but not visually arresting. Even if you spring for a bit more pizazz with the carbon option and the oil slick branding that goes with it, you get nice but not beautiful. The branding itself is also a bit generic. It's not unusual to have a large wordmark on the downtube and a painted headtube badge but the logo on the back of the seatpost is a nice touch.

Many modern aero road bikes use massive downtubes and bulky frame shapes at every opportunity but Ventum does things a little differently to the norm. The team started with the experience gained from the first bike the company brought to market. That bike was a radical triathlon bike that used extensive aero shaping to be as fast as possible. The NS1 brings things back to UCI legal but they've still allowed the wind to sculpt it. Every tube uses a truncated airfoil design that's gone through both CFD and wind tunnel verification.

There are undoubtedly more aero bikes on the market. We covered the Orbea Orca Aero recently and it's one of the most aero optimised bikes available today - in fact, it's one small step away from a TT bike. The Ventum NS1 has a different design brief though. You'll notice details such as a sloping top tube and chainstays, as well as thinner front forks, that help make this an all-day bike. The slope in the top tube helps allow flex in the seatpost and, the smaller fork tubing and 30mm tyre clearance, allows for enough flex to keep things comfortable. According to Ventum, "It's not hard to make a bike very stiff. It's also not hard to make a bike very soft or cushy - but to do both well is difficult." At key points such as the bottom bracket, head tube, and fork, the design team has dialled back the stiffness and modulated the aero focus, to try and strike the right balance.

One of the key points that has helped achieve these design goals are manufacturing partners. Instead of a traditional carbon mould process, Ventum, and its partners, use Silicon EPS moulding. This isn't something Ventum is pioneering but it is a better process that yields high-quality frames. A silicone EPS internal bladder makes what acts like a positive mould during the curing process. It helps keep the internal walls of the frame as precise as the outer. Brands such as Felt also use this technique, however, Ventum credits it as "one of the key ingredients to balancing weight, handling, and aerodynamics."

One of the key differentiators for Ventum as a brand is the customisation options. Start with the colour and choose what works for you. From here, you can pick the frame size and move on to the groupset. Shimano Ultegra or Dura-Ace 12-speed are both available as is SRAM AXS Rival all the way up to Red. You choose your crank length next and after you've selected from the base Vision or Enve wheel builds, you can customise the bar and stem lengths. The bar and stem are one piece so you'll want to choose carefully but it does mean the front end is completely free of cable faff. There's a computer mounting point under the bar that allows for a standard out-front mount but otherwise there's nothing to disrupt the wind.

Although I started off this review talking about the lack of visual clout when it comes to the paintwork, the performance and ride experience more than makes up for things. The first ride started out with the group riding through the city on pavement before leading into a 30-minute climb. I always use the first ride to get a feel for the bike but I gelled immediately with the geometry - everything just works and feels instinctual. The hill led to a lengthy descent and, at this point, I started getting more feedback from the bike. I'm always a nervous descender and I was riding with a group that was vastly overmatching my skill. To my surprise, I descended faster than usual, but the bike felt controlled and precise underneath me - even through abrupt mid-corner line changes and tight corners.

The rest of that week I rode every day. I took the Ventum NS1 up both short, steep climbs and long climbs. The Enve wheels certainly help it in a hilly setting. I also had the opportunity to test it in wind so strong that it required a steady lean to ride straight. Those were miles through Pebble Beach with the wind whipping off the ocean and across the exposed road. Any bike would have required correction but it's notable that the Ventum NS1 exhibited a steady push as opposed to any abrupt movements. Turning away from the coast, and grabbing a tailwind, immediately stopped the push which is an improvement on other aero road bikes which can move around even with a tailwind.

I mentioned it in the performance section but it's worth noting again. - when I have to start looking at the paintwork to find faults, it's a sign of a great bike. The negatives are more about preference than design issues. Overall, this is a bike that fits my riding. I like to ride long distances and the Ventum NS1 is comfortable, capable and fast. It's stable when descending and climbs really well thanks to the low weight (16lbs / 7.3kg). One of things that holds it back a little is its all-rounder attitude: there are faster aero bikes but these do come with a host of caveats.

The Ventum NS1 also does pretty well on the value-for-the-money scale. Similar bikes from brands such as Felt and Cannondale offer a little savings but haven't made the switch to the new generation of Shimano groupsets. Brands such as Specialized come in with a big price premium. An added bonus is that Ventum has stock available right now so you won't have to worry about the current state of bike shortages plaguing the market.
