Vielo V+1



Formidable road plus/adventure/gravel/gnarmac bike with speed, comfort and lovely handling

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The V+1, a road plus/gravel/adventure carbon bike from new brand Vielo, is a triumph of design. It offers a highly impressive ride: smooth and composed, fast and fun, and bristles with smart details that make it as practical as it is intoxicating. At £5,499 it's not cheap, but if you've got deep pockets and want a versatile and highly capable bike for taming rough roads and going wild in the back of beyond, you're in for a real treat.

  • Pros: Smooth, comfortable, fast, versatile, very capable, looks great
  • Cons: Very expensive, reserved paint jobs

Vielo is a new brand founded by father and son duo Ian and Trevor Hughes, who between them boast an impressive 35 years of experience in the bike industry. After years of promoting other bike brands they've decided to bring together everything they've learnt into their own offering, and in the V+1 have produced a bike that really is of the moment. There's space for wide tyres, geometry intended to work well on and off the road, versatility baked into the beautiful carbon frame... it's an exciting new offering in a crowded marketplace.

Ride and handling

What's it like to ride? In a word – or rather, three – it's fast, exciting and fun. The way it responds so lightly to your input at the handlebar and the awesome cushioning effect of the fat tyres give you the first hint that the V+1 is something special even before you reach the end of the road.

Vielo V+1 - riding 3.jpg

The pretty horrendous weather that accompanied my time with the Vielo meant that I mainly tested its 'road plus' capability, since all my local off-road routes resemble a quagmire at the moment, and nothing short of a tractor is going to cut through that gloop. I hope to be able to swing a leg over the bike again in the summer when the trails dry out to really put it through its paces on a wider mixture of terrain and challenges.

Even confined mainly to the roads, and a few harder packed off-road tracks, the V+1 still shone. Think of it as an endurance bike on steroids and you're pretty much there.

Vielo V+1 - riding 2.jpg

It's clear the V+1 has its sights set on the Open UP, one of the foremost bikes in the fledgeling but rapidly expanding gravel and adventure bike market. So it's useful to draw some comparisons, since I spent a good deal of time aboard the UP and it's one of the standouts of all the test bikes I've reviewed in the last couple of years.

First of all, let's look at the numbers. The V+1 comes in a better spread of sizes, five in total, compared to four for the UP, from XS to XL. The medium test bike I rode has a 71-degree head angle, 1,026.9mm wheelbase, 48mm fork offset, 52.5mm bottom bracket drop, 150mm head tube and 380mm reach and 554.2mm stack.

Compared to the Open UP, the V+1 is slacker, longer and lower. Those differences, though slight, are noticeable on the road. The V+1 displays a superb stability: show it a fast descent and it carves easily through the bends; rough roads don't unsettle its composure; loose surfaces don't shake and rattle your confidence. Vielo has clearly achieved its stated aim of producing a bike for the road cyclist fed up with being shaken to pieces on poorly maintained tarmac.

There's clearance for wide tyres and the big 38mm Schwalbe G-One Speed tyres, inflated to about 45-50psi for my 65kg bodyweight, combined with the slender tube shapes of the frame, intended to enhance compliance, really help to deliver a satisfyingly smooth ride. It simply glides over rough patches of broken tarmac. Nothing fazes it. Potholes, cracks, cattle grids, sunken drain covers – it handles them all so well.

Those small dimples all over the G-One tyres enhance traction in bad conditions. Rain-soaked and mud-covered lanes are their forte. They give you a good sense of just how much traction there is to play with on the road, making you feel safer travelling at speed. Add in the tubeless setup, and the peace of mind is fabulous. But mud tyres they are not, so if you plan to venture far from the road at this time of year you might want to consider a tyre change first. Or wait until the mud dries out. Vielo offers the meatier G-One Bite tyres if you want to venture off-road more frequently.

Don't for a second think those big tyres trade speed for comfort, though, because boy are they fast. Get moving and the effort required diminishes and they zip along the road at a decent pace. It was little slower than an endurance bike on 28mm tyres. The V+1 has the feeling of speed and comfort usually expected of an endurance bike but with the comfort dial turned up to 11.

Vielo V+1 - rim and tyre.jpg

It's a lot of fun to ride too. As you can tell so far, the V+1 is highly adept at smoothing out poorly surface roads and providing a very stable and composed ride, but throw loads of rapid direction changes at it and the bike comes to life, showing an agility and sprightliness that makes it a really enjoyable bike to ride. Slow and pondering it's not.

Frame design

For its first frame, Vielo has pulled a blinder. It's an impressive accomplishment. There's a high level of design and attention to detail on display, with the years of experience really shining through. It brings a lot of features and design cues that are increasingly common on such bikes, with a couple of extra ones that are often omitted.

Vielo V+1.jpg

As you'd hope for the money, it's one very light frame. A claimed weight of 890g for the frame and 400g for the fork is competitive with the new Open UPPER and it's much lighter than the 3T Exploro. It's in the same ballpark as endurance bikes like the Cannondale Synapse.

As is common with bikes of this sort, it's designed to accommodate 700C x 42mm or 650B x 2.1in wheels and tyres, allowing the bike to be tailored to the requirements of any rider and terrain. With thru-axles and disc brakes, you could easily have two sets of wheels to suit different requirements: fat slicks for road riding, chunky gravel or mountain bike tyres for off-road exploits. The supplied tyres lean towards a road preference with some off-road capability provided it's dry and hard-packed ground.

It's a lovely looking frame, with squashed oval tube shapes and a slender elegance to the way the tubes all come together. The profile of the top tube, down tube and stays is aimed at providing the best balance of stiffness and compliance, with the down tube increasing in size as it heads towards the press-fit bottom bracket. I'd wager that bottom bracket will lose it some fans, but it presented no issues during testing.

Vielo V+1 - seat tube junction.jpg

An oversized head tube accommodates a tapered steerer tube and a fork with curved round blades and a lack of bulk compared with some fork designs. It's all very pleasing on the eye, as is the paint job and reserved graphic treatment.

Vielo V+1 - fork.jpg

The frame is brimming with neat details. The front brake hose is routed inside the fork. The rear brake hose and derailleur cable enter one of two available ports on the flat down tube. There's even internal routing for the dropper post, an optional extra on this bike, with the left gear shift lever put into action to activate the RockShox Reverb seatpost. The seat clamp is tucked away inside the seat tube and accessed below the top tube, and a rubber seal around the seat tube opening prevents mud and water ingress.

Vielo V+1 - rear.jpg

Protecting the expensive carbon fibre are small metal plates on the chainstay, both behind the crankset and also near the disc brake, the latter to prevent accidentally dinging the brake rotor into the frame when installing the wheel.

Vielo V+1 - crank.jpg

There are all manner of bolts across the frame and fork for attaching racks, mudguards, bottles, tool boxes and food pods. SKS mudguards can be fitted easily, there's an extra bottle cage mount on the underside of the down tube for those rides when the standard two inside the front triangle aren't enough, or for adding a tool keg, and there's a bento box top tube mount.

Vielo V+1 - underside bosses.jpg

I'm less convinced of this last one (pictured below) simply because there don't seem to be that many bags/boxes designed around this two-bolt fixing, but there are loads of strap-on top tube bags from the likes of Alpkit, Apidura, Miss Grape and so on. The V+1 will even take a Tubus rack if you prefer to go against the trend for bikepacking bags and fit some panniers. It has all the bases covered, perhaps except a dynamo routing in the fork, but that's straying away from what this bike is designed for. Though it would be an ideal bike for a ride like the Transcontinental Race.

Vielo V+1 - top tube bosses.jpg

A common sight on adventure bikes are 1x11 groupsets. The simplicity, extra mud and tyre clearance, one less thing to go wrong, and wide-range cassettes making up for the reduced chainring number, are all very appealing on bikes designed to duke it out on any surface. Vielo goes a step further than most brands and has designed the frame entirely around a 1x11 drivetrain; there is no provision for a front mech at all. Freed from the constraints of having to accommodate a front mech, it allows the seat tube and bottom bracket to be better optimised in the pursuit of frame stiffness.

Vielo V+1 - crank 2.jpg

Naturally, it's a disc brake only bike, with 12mm thru-axles and post mount brake fixings and the option to fit a 180mm disc rotor on the fork. There's nothing wrong with post mount, all mountain bikes still use this standard, but the road market, because of Shimano's might, is largely moving over to flat mount. It's smaller, neater and lighter, but that aside there's no great advantage. Still, I'd hazard a guess that riders might prefer flat mount on this bike rather than the ability to fit a 180mm rotor, something I see no evidence of in the gravel and adventure bike market. Maybe that's the next big trend and Vielo has simple future-proofed the frame... But do you really need more power/heat management than a 160mm currently offers?

Vielo V+1 - front disc brake.jpg

Much has been made of the bike's UK focused design, but many were quick to question precisely what that means. In the case of the V+1, it's in regard to such details as the cable routing, intended to suit our preference for moto-style brakes (front brake right) and the addition of mudguard eyelets, something that is missing on several high-end carbon gravel and adventure bikes in the market. Whether that's enough to warrant the UK specificity is open to debate, but there's no denying mudguard eyelets and neater cable routing are a good thing.


You can buy the V+1 as a frameset (£2,999) or the complete bike in the same build as the bike tested here for £5,499, or without the RockShox Reverb seatpost for £5,299.

SRAM is enjoying a lot of exposure with its single ring groupsets on bikes like the V+1, and the Force 1x11 is a natural choice here: powerful hydraulic disc brakes with a mechanical rear derailleur presiding over a wide-range 10-42t cassette, and a choice of 38 or 42-tooth chainrings up front. It all works as seamlessly as usual, but top marks to Vielo for making the shifting extra silky, smoother than I've ever experienced with a SRAM Force or Rival groupset. What's your secret Vielo?

Vielo V+1 - dirvetrain.jpg

A solid and dependable list of equipment is a prerequisite on a bike like this, and the DT Swiss CR 1600 Spline 23 wheels are a prime choice. This wheelset comes straight out of DT's cyclo-cross and gravel range and combines proven DT Swiss 350 hubs with the company's star ratchet freehub, straight pull spokes and a 22mm internal width, tubeless-ready rim.

Vielo V+1 - rear hub.jpg

Weighing in at 1,720g they're not the lightest wheels but durability and strength trump such concerns on a bike designed to take some abuse. These wheels are certainly strong. If you're feeling flush, Vielo will happily upgrade to some Lightweights...

I've already mentioned the tyres, which are superb on the road, but if you do plan to embark on more off-road riding, Vielo will supply 38mm Schwalbe G-One Bite tyres, which offer a bit more, erm, bite in slippery conditions. The 38mm Schwalbe G-One Speeds are just fine for predominantly road-based action. You can read a review of these big-chamber tyres here.

Vielo V+1 - tyre.jpg

As well as developing its own frame, Vielo has also designed its own handlebar and stem to complement the frameset. While the stem is made from aluminium, the handlebar is moulded from high-modulus carbon fibre and has a 65mm reach, 120mm drop and 8-degree flare, and weighs a claimed 200g. It's a really comfortable shape when riding on the tops, and the flared drops provide a little extra control when descending.

Vielo V+1 - bars.jpg

The RockShox Reverb seatpost allows you to drop the saddle down out of the way, handy when tackling steep descents that have you off the back of the bike. It's neatly controlled by the redundant SRAM front shift lever, neat because the Reverb is normally activated by a hydraulic push button. For road riding it's of little use, and I'd steer towards the regular carbon seatpost if you don't plan to stray too far off the road, but if you have desires to really get adventurous then the ability to lower the saddle is a boon.

Vielo V+1 - saddle and dropper post.jpg

The saddle in question is a Fabric Scoop Shallow Race with carbon fibre rails. It's very comfortable. Enough said.

All that little lot adds up to 8.54kg (18.82lb) on the scales.


The Vielo V+1 is pitched into the same space that's currently occupied by the likes of the Open UP/UPPER and 3T Exploro, two very high-end, highly capable and highly accomplished adventure and gravel bikes. And like the Vielo, they come with correspondingly hefty price tags. But the Vielo does enough, and more, to hold its head high in such company.

I haven't ridden the Exploro, but I have the UP, extensively, and in my view the Vielo just nudges ahead. It's noticeably smoother than the UP on rough roads, the handling feels more natural on the road, and it's more versatile with the addition of mudguard eyelets, a godsend for UK cyclists.


The new Vielo V+1 taps into the growing appetite for bigger tyres and increased versatility, with a beautifully designed and lightweight carbon frame and fork that provide splendid handling and performance. It's fast and smooth and can be considered an alternative to an endurance bike as it's no slower but the comfort is noticeably better, yet it has the potential to be taken off-road with the right tyre choice.
