The new Fairlight Strael 4.0 pushes the boundaries of steel tubing even further – once again. This is not only by dropping a chunk of weight with the creation of a new tubeset, but by improving the ride quality to unprecedented levels I’ve never found on a bike made from any material before. It is both unbelievable and phenomenal. My only concern reviewing this Strael is that our scoring only goes up to ten – but, in true Spın̈al Tap style, Fairlight has ramped things up to eleven!

Fairlight Strael 4.0: Ride

As you may or may not know, I have ridden all four iterations of this bike, and the Strael 2.0 and 3.0 are the only bikes I’ve ever given the full 10/10 score. Both times I was left thinking – where else can this platform be improved?

I’ll go into the full details of what has changed in the next section, but I don’t think I’d be wrong in saying that Dom Thomas, Fairlight’s co-founder and designer, is a tinkerer and not one to rest on his laurels.

Working in collaboration with Reynolds Technology Fairlight has created a brand-new tubeset for the Strael 4.0, with everything bar the head tube getting a makeover. One of the main benefits of this has been a weight reduction of around 280g over the 3.0 in this 54R size frame.

Now, if you want the lightest road bike for attacking the climbs you probably aren’t going to be looking at a steel frame. If you’re young enough to have been brought up thinking that carbon fibre is the only material for race bike creation then the 1,640g achieved by Fairlight isn’t going to impress you, but for those in the know – it will. Especially from a frame that passed all ISO fatigue tests on its first attempt.

2025 Fairlight Strael 4.0 - riding 4.jpg

And that’s the whole point. The Strael 4.0 hasn’t been designed to be the fastest, lightest, stiffest road bike out there, but god damn is it ever efficient!

This fully built bike with Shimano 105 Di2, alloy cockpit, carbon seatpost, 60mm deep-section wheels and 38mm tyres tipped our scales at 8.85kg, which I reckon is very decent indeed. It certainly feels sprightly and responsive out of the corners, showing no lack of stiffness around the bottom bracket either.

2025 Fairlight Strael 4.0 - riding 3.jpg

Before my first ride on the Strael I had spent a total of four hours on my Giant TCR and the only place I found a trade off switching from a carbon bike that weighs about 1.5kg less was on those punchy, steep climbs or when pulling away hard from a standing start. In fact, when comparing both on one of my twenty-mile test loops the average speeds were pretty much identical. The TCR was running 60mm-deep wheels while the Strael was on 50mm, with each bike being quicker in different sections, as highlighted by my Garmin Connect data.

I believe a lot of the Strael’s efficiency comes from its geometry. Fairlight offers a range of five frame sizes, all available in either a regular (R) or tall (T) geometry depending on your body proportions, giving you ten in total. This allows you to get a slightly more custom fit, and in my case the Strael 4.0 fitted me like a glove.

2025 Fairlight Strael 4.0 - tyre and rim.jpg

The handling is also a delight. Being designed as an all-road bike things aren’t as steep and aggressive at the front end as they are on a race bike, so you aren’t getting that razor sharp response you would on one of those, but it is still no slouch in the bends.

The planted feeling of the Strael, created by the geometry and the huge amount of feedback you get from the frameset, gives a massive confidence boost as you enter the corners, even on technical descents.

2025 Fairlight Strael 4.0 - riding 5.jpg

I have a twisty, technical downhill that I test all road bikes on as it covers a bit of everything from off-camber chicanes through to sweeping open corners where speeds of over 50mph are achievable.

Compared to the race bikes I ride down there I backed off my entry speed a bit on the Strael, but thanks to that feedback and how well balanced it feels through the corners I could really push things on the exit, which allowed me to make up time before the next bend. Fairlight’s new Anraed 4.0 fork keeps the front end tight with no understeer, despite having enough compliance to give a planted feel even on poor surfaces.

2025 Fairlight Strael 4.0 - fork.jpg
2025 Fairlight Strael 4.0 - fork (Image Credit: Farrelly Atkinson)

Even with the large tyre clearances and full mudguard clearance this 54R still has a sub-metre wheelbase that keeps it agile and responsive at both low and high speeds.

2025 Fairlight Strael 4.0 - fork clearance.jpg

Its all-road nature means that the Strael isn’t limited to the asphalt, either, and while it’s not intended as a gravel bike (Fairlight has the Secan for that) the responsiveness and reassurance of the way it rides mean that riding on looser surfaces isn’t a white-knuckle affair. This also makes it perfect for year-round riding as a tourer, winter trainer, commuter or whatever else is going to see you on wet, mud strewn roads.

The Strael’s pièce de résistance, though, is the ride quality and comfort – I have literally never ridden anything like it before!

It sounds like a cliché, but high-quality steel alloy frames do offer a smooth ride quality. Obviously, that’s not achieved purely by the material itself, as the tubing needs to be designed in such a way to get the most out of it, including the shape of the tubes and the wall thicknesses, also known as butting.

2025 Fairlight Strael 4.0 - top tube.jpg
2025 Fairlight Strael 4.0 - top tube (Image Credit: Farrelly Atkinson)

Fairlight has made some big changes to the butting on the Strael’s tubing, creating what I believe is more compliance than the previous models while also improving stiffness in the key areas. This compliance has changed the ride feel in a big way.

While I’ll ride each bike I get in for review for around 20 to 30 hours before writing up my findings, it’s those first few miles and first impressions that give me 90% of the information of what I’m dealing with. Those early few miles on the Strael 4.0 completely blew me away.

The easiest way to describe it is that it felt like I was in contact with the saddle and handlebar, and I could feel the tyres on the road, but it’s like there was nothing in between, almost like I was floating on some kind of Zwift/Tron Legacy sci-fi machine.

2025 Fairlight Strael 4.0 - bosses.jpg

The frame and fork allow all of the feedback through from those contact points, but they nullify any buzz or imperfection from the surface that could detract from the rider/bike interaction. It is simply stunning.

Regardless of whether I was running 38mm tyres or 30mm (Fairlight supplied me two sets of wheels/tyres) the ride feel remained the same, and that’s with the tyres pumped to my usual firm preference.

2025 Fairlight Strael 4.0 - bars 2.jpg

What this means is incredible comfort too. The Strael 4.0, to steal a motoring phrase, is an incredible grand tourer. It’s a very quick bike, but one you can also cover huge distances on at speed in sublime comfort.

To sum up the ride characteristics of the Strael 4.0, I’d say it’s the road bike for anyone who doesn’t want to race. It’s fast, it’s fun, it’s responsive and it’s unbelievably comfortable, and I haven’t even mentioned the amount of versatility on offer yet.

Fairlight Strael 4.0: Design details

Fairlight probably create some of the most detailed, in-depth notes of any company in the bike industry, so if you’re fascinated by every aspect of bike design from the tubing down to the tiniest of details then it’s worth grabbing a brew and a packet of biscuits and heading over to Fairlight’s website.

2025 Fairlight Strael 4.0 - top tube detail.jpg

Under the drop-down menu Lookbooks and design notes you’ll find a 154-page PDF that covers every detail from inception to finished product. But to save you the effort, here’s a brief run-down of the updates to the Strael 4.0 over the 3.0:

New Reynolds 853 Road DZB tubing; new chainstays and seatstays; increased tyre clearance – up to 700 x 39mm tyres. The new Anraed 4.0 fork offers around 10% more compliance.

The Fairlight x Bentley Mk3 dropouts feature a removable cable stop – so whether a mechanical or electronic groupset is being used, the frame looks like it was designed specifically for it.

The newly designed down tube brake hose clips are now CNC-machined modular parts, and there’s a new 3D-printed down tube cable guide – available in 1x and 2x versions.

2025 Fairlight Strael 4.0 - riding 2.jpg

There’s an all-new 3D-printed bottom bracket cable guide for mechanical gear setups, which guides the front and rear derailleur cables, brake hose and dynamo rear light wire. And there’s a specific 3D-printed bottom bracket guide for Di2 and AXS.

From the first to the third generations of the Strael the focus was on small refinements that tweaked both the ride characteristics and aesthetics. Not so much with this latest edition, though, Fairlight having made some large and noticeable changes throughout.

Previous versions of the Strael have been made from Reynolds’ premium grade 853 steel, as is this 4.0 model – but with a slight twist.

In a collaboration Reynolds and Fairlight created a new variation called 853 Road DZB designed specifically for all-road riding. This required new tooling, something Reynolds hasn’t done for years, and new manufacturing processes.

2025 Fairlight Strael 4.0 - frame detail.jpg
2025 Fairlight Strael 4.0 - frame detail (Image Credit: Farrelly Atkinson)

DZB stands for Double Zonal Butted, and it was originally developed with mountain bikes in mind, but as Dom Thomas explained to me, he saw an opportunity to apply the technology to create this all-road version.

In simple terms Fairlight has added material to the high-stress areas of the tubing, increasing the wall thickness, while reducing the thickness elsewhere in the tube. This two-pronged attack increases strength where it’s needed while reducing weight.

2025 Fairlight Strael 4.0 - fork cable route.jpg

For instance, the Strael 3.0’s top tube had wall thicknesses (head tube end first) of 0.7/0.4/0.7mm. The Strael 4.0 goes 0.8/0.6/0.4/0.7mm. Dom considered changing the 0.7mm thickness at the seat tube end to 0.6mm, but after finding that the tube could deform during alignment it was kept at 0.7mm.

Every tube apart from the head tube has been scrutinised and tweaked to create this new frame, which is all covered in Fairlight’s Lookbook.

2025 Fairlight Strael 4.0 - seat tube junction.jpg

This has seen significant investment from Fairlight – but it’s a gamble that has definitely paid off.

You’ll see from the photos that the Strael’s tubing is also made up from many different profiles, all of which have been tried and tested to create the stiffness and ride quality required.

Fairlight has stuck with the 68mm BSA threaded bottom bracket design, but the shell itself has seen some changes to reduce weight. After welding the frame is positioned in a jig where a CNC milling machine cuts the threads and reduces the internal wall thickness of the shell between the threads. This trims around 67g in weight.

2025 Fairlight Strael 4.0 - bottom bracket.jpg

The most noticeable change aesthetically has been the seatstays. The gauge has been increased from 14mm to 16mm to increase resistance to pedalling forces without compromising on comfort. To achieve this the seatstays have been flattened and ovalised to create some compliance.

2025 Fairlight Strael 4.0 - seat stays.jpg
2025 Fairlight Strael 4.0 - seat stays (Image Credit: Farrelly Atkinson)

In terms of material the seatstays are Reynolds 4130 (as is the machined head tube) and the chainstays are Reynolds 725. The latter have been redesigned to increase tyre clearance from 36mm to 39mm (measured) while still maintaining the ISO required 4mm of clearance either side.

2025 Fairlight Strael 4.0 - head tube.jpg

The Strael is designed to take full mudguards and rear rack, and you’ll find the mounting points for each in the traditional position, so there’s no need to manipulate the stays of off-the-shelf guards.

2025 Fairlight Strael 4.0 - cassette.jpg

Tyre clearance with full guards is 35mm.

The frame has also been designed to accept dynamo lighting, which after leaving the fork passes internally through the down tube. It exits near the bottom bracket before being guided towards the chainstays where more internal routing takes it to the dropout, where the rear light can be mounted. In some impressive attention to detail Fairlight has allowed this to be mirrored on both chainstays so you can run your light on whichever side you wish.

2025 Fairlight Strael 4.0 - chain stay cable route.jpg

Fairlight has stuck with external gear cable and brake hose routing, after all, their bikes are designed to be functional by design. I have no issue with that whatsoever, and it certainly makes things easier from a maintenance point of view.

2025 Fairlight Strael 4.0 - lever.jpg

Things like the cable guides that mount to the bottom of the down tube have had a major revamp, though, bringing a more modular approach. They work with all kinds of groupsets and anything that isn’t required for a specific setup can be omitted.

2025 Fairlight Strael 4.0 - front disc brake.jpg

Bringing everything together are the CNCed aluminium pieces and laser-cut washer plates from Bentley Components that make up the modular setups for the rear dropouts, rear mech attachment, dynamo rear light mounting, and which bring a premium finish to the bike.

2025 Fairlight Strael 4.0 - rear disc brake.jpg
2025 Fairlight Strael 4.0 - rear disc brake (Image Credit: Farrelly Atkinson)

As someone who spent seven years as a CNC programmer and machinist, I can recognise the skill in machining the intricate parts, and the way they have been machined to achieve the finished look.

The rear mech attachment options cover pretty much every derailleur on the market including SRAM’s T-Type and Shimano’s Direct Mount. This modular system also allows Fairlight to future-proof the frame against any new mech designs.

2025 Fairlight Strael 4.0 - rear drop out.jpg

The washer plates bring a level of protection to your frame, stopping the paint from getting damaged when fitting or removing things like mudguards.

The frame itself is manufactured in Taiwan and finished to an exceptionally high standard throughout. The welds are incredibly neat, and everything is finished off with a luxurious paintjob.

The model we have here is the Ochre, while Stealth (a gloss black paintjob with subtle colourful details), Monochrome and Pearlescent Blue make up the rest of the range.

Fairlight Strael 4.0: Proportional geometry

Since its inception all of Fairlight’s bikes use what it calls proportional geometry, which means that each frame size has two options, regular (R) and tall (T).

The regular frames are lower at the front and longer in reach, designed for people with shorter legs and a longer back, but can also be used by riders who want a lower, racier ride position.

2025 Fairlight Strael 4.0 - head tube.jpg

2025 Fairlight Strael 4.0 - head tube.jpg

The tall bikes are higher at the front and shorter in reach, so for riders with longer legs and shorter torsos.

For instance, this 54R has a 546mm top tube, 532mm seat tube and 124mm head tube, whereas the 54T’s measurements are 548mm, 536mm and 157mm respectively.

2025 Fairlight Strael 4.0 - rear.jpg

The stack and reach figures for the 54R are 548mm and 386mm, while the 54T’s are 580mm and 378mm.

2025 Fairlight Strael 4.0 - front.jpg

Their head angles are the same at 72.25°, as are the seat tubes sitting at 73.75°. Both have a fork rake of 45mm and chainstays of 419mm although the 54R’s wheelbase is slightly shorter at 998mm compared to 1001mm for the 54T.

Fairlight’s website offers a fit calculator, or you can provide data from a bike fit. When speccing your bike you also have control over stem length, handlebar width and crank length.

Fairlight Strael 4.0: Finishing kit and pricing

The Strael is available as a frameset for a starting price of £1,499 without a headset. An FSA Orbit option adds £35, one from Hope adds £110, while a Chris King costs £210.

You can also spec many upgrades like dynamo lighting and bottle cages.

2025 Fairlight Strael 4.0 - drivetrain.jpg

Full bikes start at £2,649 with Shimano’s 105 mechanical groupset, DT Swiss E1800 wheels and FSA finishing kit including an alloy bar and stem plus a carbon seatpost. Various wheel and tyre upgrades are also on offer, plus those dynamo and headset choices mentioned above.

The base Ultegra Di2 build is £4,049 while Dura-Ace Di2 starts at £4,999.

Our review bike has a 105 Di2 groupset and Hope headset upgrade which when paired with the cheaper set of wheels, the Hunt 4 Season Pro Disc and 30mm Continental GP5000s, comes in at £3,369.

2025 Fairlight Strael 4.0 - fork detail 2.jpg

The deep-section Hunt 50 Carbon Disc wheels that we also had would up the price by £500, and while Fairlight doesn’t offer the 38mm Schwalbe Pro Ones as a drop-down option (I was given them to exploit the increased tyre clearance of the frame and fork) a set of 35mm GP5000 AS TR tyres will add £40. So, we’re looking at about £3,910 all in.

2025 Fairlight Strael 4.0 - tyre.jpg

A full dynamo set up with Son front and rear lamps will add £370.

The finishing kit is well chosen and works really well with how the Strael rides.

2025 Fairlight Strael 4.0 - stem.jpg

The FSA Gossamer handlebar is comfortable and offers plenty of stiffness, and the FSA Energy SCR stem does its job without any fuss.

2025 Fairlight Strael 4.0 - bars 1.jpg

The Argo saddle is quite bulky, but I found it comfortable for all kinds of riding. It’s probably the only bit of kit I’d tweak, switching to one of my favourites.

2025 Fairlight Strael 4.0 - saddle.jpg

The beauty about the Strael’s frame is that it’ll work with whichever groupset you want to use it with. It has that workman-like quality that matches well with 105 mechanical, while also having the ride quality and high-end finish that even when draped with Dura Ace it won’t be punching above its weight.

Value

As always, the obvious competitor to the Strael is Mason’s Resolution. The reason being that Dom Mason (Mason Cycles’ head honcho and designer) has the same sort of dedication as Dom Thomas for attention to detail and driving forward the capabilities of metal alloy tubing used in bike manufacture.

The latest Resolution 3 impressed me massively when I reviewed it and it is a beautiful-looking bike. The frame is manufactured in Italy from a custom-specced blend of Columbus Spirit and Life tubing, while the full-carbon fork is designed by Mason and created using its own mould, just as the Fairlight fork is.

Tyre clearance on the Mason is 35mm and there’s also provision for full mudguards and a rear rack.

The Resolution costs £1,795 as a frameset, or a 105 Di2 build with Hunt 4 Season Disc wheels and 28mm Continental GP5000 tyres will set you back £4,000.

It’s been a few years since I reviewed Condor’s Fratello Disc but it was a bike that impressed me. The frame is made from Columbus Spirit triple-butted tubing and has a claimed weight of around 1,950g. It had a great ride quality but hasn’t been updated to accept bigger tyres than 32mm.

The frameset costs £1,449.99 while a 105 Di2 model with Mavic Ksyrium S wheels, Hutchinson Fusion 5 tyres and SKS mudguards costs around £3,350.

Standert bikes has the Pfadfinder in its all-road range, and like the Condor it uses Columbus Sprit tubing. It has mudguard mounting and 38mm tyre clearance, and it’s made in Europe. I haven’t ridden one, but I did review its Kreissäge RS race bike, and wasn’t totally impressed with the ride quality.

Pricing is competitive, though, with a 105 Di2 build coming in at €4,799, about £4,060, but you’ll need to factor in €220 (£186) for delivery from Germany.

Conclusion

In the last 15 years of reviewing hundreds of bikes I have never known one that hits perfection when it comes to how it rides… but this Strael 4.0 does. It’s stunning, incredible just how brilliant this bike is. Add to that the amazing attention to detail, and the fact that everything has been designed for a purpose, it also gave me the feel of riding a custom-built bike. It looks stunning too, and when you take everything into consideration the value is impressive too.

Verdict

The closest bike to perfection I’ve ever ridden…

Tell us about the geometry of the frame and fork?

The Strael is offered in two different geometries for each size to accomodate different body shapes. Either long legs and short torso, or short legs and a long torso.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

I found the stack and reach figures to be perfect for me when riding the R version of the geometry.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

Incredibly comfortable, the ride quality is amazing.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

The frame and fork have plenty of stiffness and hard efforts out of the saddle highlighted no flex.

How did the bike transfer power? Did it feel efficient?

For the kind of bike it is the bike transfers power very well indeed, and the whole ride feels very efficient.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

No

How would you describe the steering? Was it lively neutral or unresponsive?

On the sporty side of neutral.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

The Strael is an all-road, versatile kind of bike and the steering is well suited. It’s handling isn’t as quick as a race bike’s, but it is sharp enough and has a very planted-feeling front end.

Which components had the most effect (good or bad) on the bike’s comfort? would you recommend any changes?

Both the Scwalbe Pro One and Continental GP5000 tyres supplied on the two wheelsets offer a supple ride and the Fizik Argo saddle works well.

Which components had the most effect (good or bad) on the bike’s stiffness? would you recommend any changes?

The FSA cockpit gives a stiff front end whether cornering or braking hard.

Which components had the most effect (good or bad) on the bike’s efficiency? would you recommend any changes?

The deep-section Hunt 50 wheels definitely improved the efficiency due to their aerodynamics.

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?

These scores are based on the Hunt 50 Carbons that I spent most of the time using, rather than the same company’s Four Season wheels. Both wheels are very good, offering great reliability and the deep-section rims add an aerodynamic edge.

In my mind the Strael 4.0 is faultless. The design is brilliant, hugely versatile and incorporates the latest trends in the road bike market. On top of that the ride quality is perfect, and all things considered I think it’s well priced too.

Overall rating: 10/10
