The second era Ventum NS1 makes an attempt to mix aero styling into a light-weight bundle to create an all-round race bike. The brand new bike’s set of updates are all modern and largely add worth to the design.
The proprietary ending package the bike makes use of is hit or miss: the seatpost provides a great deal of compliance to an in any other case stiff frameset however the built-in bar/stem is simply too versatile and makes the bike’s dealing with really feel imprecise when sprinting or climbing out of the saddle. Fortunately the normally-sized fork steerer accepts aftermarket stems and bars, although these will should be bought on prime of the bike as they don’t seem to be provided within the construct configurator.
Its do-everything remit does imply the NS1 is considerably generic in seems (extra specialised bikes are sometimes more original in design) but it surely does ship a rounded efficiency out on the street that many riders will have the ability to take pleasure in and use to their benefit. Ventum’s direct-sales mannequin means pricing is aggressive and there’s a diploma of spec customisation through the buy course of that provides worth too.
Ventum NS1 growth
Being a US-based model that’s consumer-direct and comparatively younger, Ventum isn’t a widely known identify within the UK. In any case, those that do recognise it usually tend to comprehend it for the model’s eccentric One triathlon frameset – seen from the non-driveside, the body form bears extra resemblance to Mexican fictional vigilante Zorro’s ‘Z’ calling-card than it does to a standard double-diamond design, the down tube and seatstays having been eliminated in an try to enhance aerodynamic efficiency.
Whereas the NS1 has been knowledgeable by the expertise gained through the growth of the One, it’s itself comparatively typical against this. That stated, the model’s racy all-rounder is quick changing into Ventum’s hottest bike and it has simply been up to date for the primary time, the unique design having been launched in 2019.
‘Our second era NS1 has been considerably modified,’ says Ventum’s Harry Keeran. ‘Together with a reiterated composite development, it sports activities wider 35mm tyre clearance, simplified inside cable routing, a extra compliant proprietary cockpit, a T47 backside bracket and the adoption of SRAM’s UDH derailleur hanger normal.’
That’s nearly essentially the most up-to-date assortment of updates you’re prone to discover in a brand new bike.
Ventum NS1 frameset
It joins the GS1 gravel bike in Ventum’s drop-bar line-up, and identical to with their radical forebear, the One, aerodynamic effectivity is claimed to be a main design attribute. Aero-slipperiness has been achieved with extra refined methods than merely distending tube profiles although, considered one of which is evidenced within the NS1’s clear strains and sharp tube angles.
Ventum says this promotes the clear separation of air off the again of the tubes, however such tight corners on tube profiles are stated to be arduous to attain in composite constantly. As such, Ventum says there’s no scarcity of superior fabrication methods utilized in creating the NS1 frameset, corresponding to a ‘Silicone EPS Double Mould’ development (crudely, this does what it says on the tin: one mould to make a foam mandrel, which is roofed in silicone, then wrapped within the body’s composite, earlier than being cured in a second mould), and there’s even that enigmatic materials graphene sprinkled into the resin of Ventum’s pre-preg carbon swatches.
By being sensible about how the bike’s aerodynamic attributes are created, Keeran says that allowed it the chance to construct in different attributes to make NS1 extra well-rounded. For instance, shallower tubes meant the frameset might be lighter.
Whereas the bike’s clear end and my trouble-free check interval utilizing it recommend the manufacturing strategies used to create the NS1 had been certainly high-quality, the result’s a considerably generic-looking race frameset. Fortunately although, customers have the flexibility to customize their bike to a sure diploma via the bike-builder on Ventum’s web site.
All bikes use the identical frameset tier, which will be dressed up or down depending on finances at no additional value. For the client severe sufficient to spend important cash on a motorbike, the liberty to decide on is prone to be a horny facet of shopping for an NS1.
Ventum NS1 construct
An space the place the client is restricted to an extent is the bike’s built-in bar/stem. There are 12 measurement choices, however no various or third-party two-piece setups (although the frameset will accommodate them, because of its regular fork steerer). The cockpit was particularly designed for the brand new NS1.
‘The suggestions we received about our outdated NS1 was that the cockpit was too stiff, so we addressed that this time spherical,’ says Keeran.
The brand new cockpit options closely flattened, deepened tops to minimise drag and although the hoses from the levers seem hidden, they merely run in cleverly sculpted channels on the element’s underside, so in upkeep and adjustment phrases, fortunately they’re nearly as good as externally routed.
A proprietary seatpost on the rear matches the in-house entrance finish. Utilizing an outwardly easy and svelte profile just like the frameset it suits in, its D-shaped cross part and 20mm layback makes an attempt to advertise fore-aft flex to enhance consolation. Its saddle clamp is a straightforward affair, utilizing one bolt, profiled clamps on a rocker-type head to creating adjusting simple.
SRAM’s Force AXS groupset adorns the body, which is a stable possibility for many riders. You get the identical performance as top-tier RED AXS at a cheaper price, simply with a trade-off in weight, which does contribute to the bike’s middling general 7.7kg determine on the scales. That stated, gear shifts are correct and SRAM’s hydraulic disc brakes are wonderful, proving to be highly effective and silent in additional using situations than Shimano’s callipers, in my expertise, though Shimano’s top-level designs do have a tendency provide extra tactile suggestions on braking energy.
A construct spotlight are Zipp’s 303 S wheels. They boast a contemporary 23mm inside rim width and a flexible 45mm depth, and weigh an honest 1,558g regardless of being aggressive in worth phrases.
The tyres wrapped round them although had been a bit of underwhelming. The thick casing and heavy weight of IRC’s 30mm Components Professional TL X-guard tyres would undoubtedly final a very long time, I skilled no trace of any fragility and so they felt like they gripped fairly properly, however typically they felt picket and detracted from the NS1’s in any other case nimble experience.
Ventum NS1 geometry
A lot of the NS1’s geometry numbers are fairly typical for a race bike – the scale Giant on check (which is roughly equal to a 56cm body) makes use of parellel 73-degree head and seat tube angles, and the neat 410mm chainstays make sure the NS1’s general wheelbase is saved to 994mm. Married to the 58mm of path created by the pinnacle angle, 45mm fork rake and 30mm tyres, the NS1 ought to react eagerly to turning enter.
The bike’s 395mm attain is once more regular, although because of the brand new bike’s recessed head tube design (the pinnacle tube is scalloped out in order that the headset spacer/stem transition is flush with the highest tube), its stack is notably low for a given measurement, at 552mm on this case. This could assist the rider obtain a decrease physique place – a boon for drag discount – although sensibly, by not extending the attain as properly, the NS1 match traits don’t turn into too aggressive, which might danger excluding some potential riders.
The NS1 is obtainable in six sizes, which is nice, and it caters notably properly for the center of the scale vary, with M, M/L and L sizes all out there. Nonetheless, all sizes use the identical fork design. This implies path varies considerably between sizes on the smaller finish of issues, which means the bike is prone to experience barely in a different way relying on rider top and measurement chosen. It could be good to see extra fork rakes used to higher homogenise dealing with traits throughout the scale vary for the NS1 – utilizing the identical fork simplifies manufacturing and reduces value for the model however shouldn’t be the perfect outcome for the top client.
Using the Ventum NS1
First impressions of the bike had been dominated by the unusual-feeling handlebars. The aerofoil profile of the tops along with the hose recesses inherently signifies that the bars’ cross-section isn’t very massive, and due to this fact in sure conditions out on the street the cockpit is noticeably versatile.
Whereas sprinting within the drops or tackling brief, sharp climbs on the hoods, the twist of the bars made the bike’s dealing with really feel a bit of imprecise, which was a disgrace as a result of the NS1’s properly composed geometry in any other case meant it was a pleasure to steer. 58mm of path nestled inside a wheelbase of 994mm on this M/L pattern meant the NS1 felt pure and easy-going to manage, tipping into turns intuitively however remaining secure at excessive velocity.
However, the cockpit’s compliance meant outdoors of high-torque using conditions the entrance finish of the bike was distinctly easy, which was a sensation that prolonged to the again of the bike courtesy of its D-shaped, offset seatpost.
That element supplied a tangible diploma of fore-aft flex too, which means that cumulatively, the NS1’s ending package makes the design unusually snug for a race bike. If the person was to totally exploit the tyre clearance on provide, I’d wager the resultant bike could be an easy-riding, fast-feeling, do-it-all machine.
Whereas its extraneous elements are compliant, it’s obvious that at its coronary heart the NS1 is a inflexible bike. My arms may need been twisting on the bars, however there was no proof of any important quantity of that motion being generated within the entrance triangle of the body, nor on the backside bracket junction.
It’s spectacular that Ventum has achieved such a sturdy pedalling platform given the comparatively slender backside bracket shell width necessitated by the outboard T47 backside bracket (the place the bearings are housed in cups that protrude from the body, somewhat than buried inside as with a T47 inboard or PF86 normal), and skinny chainstays that enable the 35mm tyre clearance. Nonetheless, the chainstays are markedly tall, which helps recuperate a few of their cross-sectional measurement, and due to this fact stiffness.
Ventum NS1 evaluation abstract
General, regardless of producing a motorbike that may’t fairly match the originality of its triathlon-focussing sibling, the updates Ventum has launched to the second era NS1 have meaningfully introduced the platform ahead. It now gives a recent set of options that allow it compete with, if not surpass, some completed bikes in a really hotly contested class.
Options just like the spec customisation, in addition to its aggressive pricing it doesn’t matter what construct is chosen, assist Ventum make a stable case for the NS1.
I want to see Ventum provide extra cockpit choices at buy somewhat than forcing the client its personal built-in bar/stem, and extra effort must be put into homogenising the potential dealing with traits of the bike throughout all sizes, however in any other case the NS1 is a motorbike that it virtually unattainable to dislike and can serve loads of riders properly.
