The Sunpeed Invincible Expert is a budget-friendly ‘allroad’ bike that comes across as a reasonably compelling, if slightly confusing, proposition. When many mainstream brands are pushing prices higher, Sunpeed offers a full carbon frame with a genuine Shimano 105 12-speed groupset for a fraction of the cost. However, navigating the brand’s lack of online documentation, its unique sizing, and its identity crisis requires some work.
First impressions and specs
The buying process starts with a bit of a mystery, as the Sunpeed website, and consequently the Vride site (the UK distributor), are notably poor at providing technical details. It is therefore hard to know exactly what will be arriving before the box turns up.
Once it does, however, the Invincible Expert is reasonably impressively specced. Unlike many budget bikes that cut corners with non-series cranks or chains, Sunpeed provided a complete Shimano 105 R7100 mechanical 12-speed groupset. The only non-series parts were the generic 6-bolt disc rotors. Everything else, including the cassette and chain, was proper 105 series.
It’s worth noting however, that Sunpeed will be moving the base spec up from the mechanical 105, which we had on test, to the excellent 12-speed 105 Di2.
The bike features a sleek one-piece carbon bar and stem with full internal cabling. This gives it a very tidy, high-end look, though it does make maintenance a challenge. You have four cables (two hoses and two gear cables) running through the headset.
The gears were well-indexed, requiring only a single turn of the barrel adjuster as the cables settled in. The bar taping was also pretty high quality and neatly finished.
The sizing conundrum
Prospective buyers must be extremely careful with sizing. Sunpeed uses sizing more in line with Asian markets than Western standards. The bike on test is an XL, which sounds massive, but in reality it sits somewhere near a Western medium.
I am 1.74m tall and usually ride a small or medium. The Sunpeed XL fit me well enough, and I would say that looking at the sizing chart, it’ll only fit you up to about 1.85m. For my size, if I were to buy one of these, I’d go with the large I think, so bear that in mind.
Furthermore, the integrated cockpit means you are stuck with the dimensions provided, as there are no options to change its size at the point of purchase or buy different proprietary versions later. The XL comes with a 110mm stem and 42cm bars. While there is a slight flare to the drops, the hoods measure closer to 40cm. The tops are also quite deep. While they look sleek, smaller hands might struggle to wrap around them safely.
Similarly, the 105 hoods themselves are quite large, which could be a struggle for those with smaller hands. This shouldn’t however be a problem with the Di2 option which they are moving to.
Vride has said it plans to stock from a M up to XXL, but currently only M to XL is available. This should mean all riders from about 1.58m to 1.94m should be catered for.
Allroad, race, or endurance?
Sunpeed markets this as an allroad bike, but it feels like it’s having an identity crisis. The geometry is reasonably aggressive and racy, and the marketing speaks of, “speed, accuracy, and pure performance.” However, an allroad bike usually implies versatility, yet this frame has no mounts for mudguards or racks. To me, a true allroad bike should have room for at least 35mm tyres and some utility mounts.
The biggest detractor from the allroad tag is the tyre clearance. Sunpeed claims it can fit 32mm tyres, but in reality, 32mm on a modern, wider carbon rim would likely rub. I tested 30mm tyres on a wider rim – which measured up to 32mm with callipers – and it was a pretty tight fit. Don’t expect to run wide rubber on modern rims here without checking the clearance properly.
Similarly, the frame design looks something more akin to the likes of a Specialized Tarmac with a reasonably small head tube, dropped seat stays and a long-ish top tube, none of which imply allroad to me.
I’d encourage you to look thoroughly at the geometry charts before determining whether this bike is for you. Having looked at the new Canyon Endurace CF SLX geometry chart, I’d say the two are pretty similar, so the Sunpeed is definitely an aggressive bike – although there are enough headset spacers so that you can fine tune your position there.
Ride quality and components
On the road, the bike is surprisingly quick. During a commute (with a tailwind), I managed to set a bunch of PRs that genuinely surprised me. Other times it hasn’t felt quite so nippy, but generally I’d say it feels a decent speed.
I have however been really underwhelmed by its comfort. My commute goes down the Bristol-Bath bike path. Riding that every day, along with a bunch of different lanes and bigger roads, the ride is very harsh. I’ve found the frame seems to transfer an awful lot of road buzz up into the rider, and if you hit anything bigger than a pebble, you really know about it. I’ve had a few moments where I’ve hit a small pothole and I’ve felt like it’s nearly caused me to crash.
The ride quality is definitely hampered by the stock wheels. While the hubs seem all right for the price, the aluminium rims are absolutely rubbish. They are incredibly narrow, meaning a 28mm tyre measured just over 26mm on my callipers. Furthermore, the rims are not tubeless compatible and the cheap-feeling Maxxis Detonator tyres don’t help the ride feel.
I would personally recommend looking at the next model up which includes modern carbon wheels for £2,099.99, otherwise, you’ll be looking to upgrade these almost immediately. I’ve tried the bike with some of my own carbon rims, and whilst it’s a nicer ride, it didn’t do an enormous amount to make the ride less harsh.
The proprietary D-shaped seat post hasn’t slipped once during testing, which is a big plus. It offers a surprising amount of flex for vertical compliance, though that can feel a bit unnerving if you aren’t expecting it to move that much.
Conversely, the included saddle is quite poor. It has excessive flex in the wings and became uncomfortable for me after about an hour of riding. That said, everyone’s backside is different, and so what doesn’t work for me might work for you.
Build quality and maintenance
The build quality is generally good. I found grease in most of the right places, which is better than many bikes bought directly from the Far East. However, I’d still recommend a full bolt check, especially if you plan to ride through the salty UK winters.
The paint job is also pretty good. There are a few places where you can see that the masking tape job wasn’t the best, so there’s little bits of overspray, but it’s nothing catastrophic. The colour we had on test is a really nice, almost pearlescent purple, and it looks great in the sun. It’s easily my favourite part of the bike.
Value
The Sunpeed Invincible Expert is quite a lot of bike for the money. It rides quickly and the Shimano groupset works a treat. However, it’s a bike of contradictions – relatively aggressive geometry, but labelled as ‘allroad’ with limited clearance and confusing sizing.
If you can navigate the Asian sizing and plan to upgrade the wheels, it’s a decent platform, and for those in the UK, having a distributor like Vride for spares and maintenance adds a much-needed layer of security and after-sale care.
Another option for a similar price is the Ribble CGR AL, an aluminium gravel bike. For £1,799, it comes with the same 105 mechanical groupset and DT Swiss aluminium wheels. There is room for 50mm tyres, and all sorts of mudguards and racks. Stu did think that the ride was harsh though, and similarly to the Sunpeed, the reach measurement is quite long. Ribble is definitely a more established brand though, giving you a bit more confidence long term.
Another British brand with a similar offering is Boardman, with its SLR 9.0 Carbon, which comes in at £1,800. Stu felt it was a great balance of raciness whilst still being comfortable. It comes with tyre clearance of 36mm, without claiming to be an allroad bike, which is a lot more than the Sunpeed. The only downside is the non-series chainset. It comes with mudguard mounts, but does weigh just over 9kg.
All in all though, it’s not a bad bike, and this version at £1,700 is a good deal. If you want something cheapish, that is ready to ride, this wouldn’t be a terrible option.

Any further comments on quality?:
Generally, the frame and fork are pretty well made. There is some overspray in some parts of the frame, but generally the paint job is nice.
Any further comments on performance?:
As a road bike, it’s fine. As an all-road bike, it leaves a lot to be desired. There is minimal clearance, and the ride is harsh.
How does the price compare to that of similar products in the market, including ones recently tested?:
It’s on the cheaper end of the spectrum, with a carbon frame, and bars, with cheap wheels for £1,700 in this build. The Di2 option will be a bit more though, of course.

Tell us what the bike is for and who it’s aimed at. What do the manufacturers say about it?:
Sunpeed says this is an all road bike, but the company also says about it being a carbon race platform, so I’m not sure who this is really aimed at.
Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options:
The model on test is one up from the bottom of the range, with the lower option coming with off brand parts like chainset. The model on test will be superseded by the 105 Di2 option soon though.
Tell us about the build quality and finish of the frame and fork:
Generally, the frame and fork are pretty well made. There is some overspray in some parts of the frame, but generally the paint job is nice.
Tell us about the materials used in the frame and fork:
It’s all carbon fibre. Absolutely no clue on what type though, which comes back to the lack of information available on the website.
Tell us about the geometry of the frame and fork:
This is the confusing one. On one hand it’s quite aggressive and racey, but on the other, the bars are wide, and the seatpost comes with a chunk of layback, so I’d say a pretty aggressive geometry generally.
How was the bike in terms of stack and reach? How did it compare to other bikes of the same stated size?:
Compared to any western XL, it’s tiny. It’s much closer to a M or L at most. It has quite a long reach compared to its other measurements though. The head tube is quite short, but it does come with a lot of spacers, meaning you can get the bars quite high if you want.
Was the bike comfortable to ride? Tell us how you felt about the ride quality:
Not particularly. It’s a harsh ride, and all bumps go through your hands a lot.
Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?:
The bike generally feels very stiff, other than the bars, which flex a lot when you try to do so.
Was there any toe overlap with the front wheel? If so, was it a problem?:
As someone used to small bikes, toe overlap wasn’t a problem for me on this bike.
How would you describe the steering? Was it lively, neutral or unresponsive?:
I’d say it feels quite lively, maybe due to a much shorter stem than I’m used to, but it turns easily.
Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?:
The handling is generally fine. It feels pretty confident, goes round corners okay, although I’d personally like to have the bars a little lower to match how I normally set my bikes up.
Which components had the most effect (good or bad) on the bike’s performance? Would you recommend any changes?:
The wheels are rubbish. They are super narrow, not tubeless compatible, and make the ride even more harsh. The complete Shimano groupset is very reliable though, and it’s nice to have everything the correct series.
Any comments on power transfer?:
Generally I’d say it’s okay. You lose some efficiency due to the harsh ride, so rolling resistance isn’t going to be great, but the bike doesn’t feel like it loses power in itself.
Any comments on acceleration?:
It accelerates pretty well, and this means you can get off the line pretty quickly when the lights change for example.
Any comments on sprinting?:
Similar to accelerating, it feels pretty decent to sprint on. I would personally rather narrower bars to sprint with, but that’s more personal.
Any comments on stability?:
Coming from an aero bike with deep profiles, this bike doesn’t get affected by wind much at all, and it feels generally very stable, unless you hit any kind of bump.
Any comments on cornering?:
It corners decently, I would rather narrower bars for more confidence, but again that’s personal.
Any comments on climbing?:
This climbs pretty well, it has a nice easy bottom gear, and being quite light means it’s not a bad climber at all.
Any comments on drivetrain performance?:
Generally this was great, 105 is very dependable, and reliable.
Any issues with drivetrain durability?:
No issues with durability, it’s just worked so far.
Tell us some more about the drivetrain. Anything you particularly did or didn’t like? Any components which didn’t work well together?:
All worked well together. Everything other than the rotors are 105 series, so they’re all high quality and work well.
Any comments on wheel performance?:
The wheels are rubbish, with narrow rims which aren’t tubeless compatible.
Any issues with wheel durability?:
No issues so far, and in fairness the hubs seem decent, but I wouldn’t be surprised if it was easy to ding these rims.
Any comments on wheel weight?:
They’re not too heavy for aluminium, in fairness.
Any comments on wheel comfort?:
Not comfortable at all, especially with the tyres they come with.
Tell us some more about the wheels. Did they work well in the conditions you encountered? Would you change the wheels? If so, what for?:
I’d swap the wheels immediately for almost anything else. Something like a DT Swiss aluminium wheel will be 10 times better.
Any comments on tyre performance?:
These tyres are shocking. They’re not even listed on the Maxxis site, and can only seem to be bought off Aliexpress. I wouldn’t trust them in the slightest and would bin them immediately.
Any comments on tyre durability? How much did the tyres wear during testing?:
They have lasted ok, but for my own safety, I have been avoiding using them much.
Any comments on tyre weight?:
They’re nothing extraordinary.
Any comments on tyre comfort?:
They’re bad. A very cheap tyre.
Tell us some more about the tyres. Did they work well in the conditions you encountered? Would you change the tyres? If so, what for?:
I’d swap them for anything else.
Any comments on brake performance?:
105 is great.
Any issues with brake durability?:
No.
Tell us some more about the brakes. Did they work well in the conditions you encountered? Would you change anything? If so, why?:
They work great, as Shimano 105 always seems to.
Any comments on controls performance?:
105 is great.
Any issues with controls durability?:
Nothing, 105 is bombproof.
Any comments on controls comfort?:
The hoods are a little large is all.
Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?:
The mechanical 105 is a larger hood, so smaller hands may struggle.
Did you enjoy using the product?
Not majorly.
Would you consider buying the product? No.
Would you recommend the product to a friend?
If they were adamant on an off the shelf, ready to ride bike, without a need for lots of comfort, maybe.
Use this box to explain your overall score
A generally okay bike: it works and does what you want it to do. But whilst it’s pretty cheap, I don’t think it’s actually that great value, as lots of the components will need to swapped straight away, or soon. The ride also isn’t great.
