The new Reilly Fusion certainly looks the business, with its investment cast tube junctions creating a frame that could almost be mistaken for carbon fibre rather than titanium. You still get that excellent titanium ride feel, though, which combined with the geometry means you can ride the Fusion as hard and as fast as you like, in comfort for many, many miles.
Often, the reason for choosing a titanium alloy bike comes down to the ride quality of the material; it tends to have the feeling of an in-built vibration reducer, allowing even the stiffest of machines to deliver a decent amount of comfort. That does depend on the makers knowing what they're doing at the design stage, of course. The team at Reilly certainly do.
With its aero-esque tube shapes, the Fusion looks every inch the high-speed racer, and on the whole it is. The performance is great.
At 8.27kg it's a decent weight for a metal bike, meaning it's lively off the line or on the climbs, and it ploughs through undulating terrain as if it's the flatlands.
With impressive stiffness levels up front and throughout the lower sections of the frame, focused around the bottom bracket, the Fusion also feels very responsive. I loved the situations where I had to get out of the saddle and fling the bar side to side in a flurry of cadence and power.
The Reilly certainly has plenty of get up and go.
But a glance at the geometry table shows that the Fusion isn't just about being flung through the bends, or clinging to the rear tyre of the rider in front of whatever professional or amateur peloton you are part of.
The steering takes a marginal step back from that of a full-on aggressive race machine, meaning the Fusion feels just as at home on longer road rides, from the club run through to a sportive or self-planned day ride.
It makes the Fusion a bike that is easy to ride fast, but without the associated twitchiness of a race bike. It's capable of being raced, but doesn't feel like it has to be.
With a wheelbase shorter than a metre (size medium), the Fusion feels nimble underneath you, and with the buzz-taming nature of the frame it feels very composed.
This is a match made in heaven, giving you the confidence to push the Reilly hard through the corners as it feels planted, but responds well to quick direction changes either through the handlebar or by a shift of your body position.
The full-carbon fibre fork backs up the frame's performance too. There is plenty of stiffness on offer here, with the legs taking the loads from hard braking or being banked over in the bends without any noticeable flex, without any compromise to the ride feel on rough road surfaces.
Overall, the Fusion rides with all of the excitement and involvement of a great race bike, with the manners and ride quality of a quick endurance machine. It's a difficult balance to pull off, but Reilly has done it.
The Fusion, like many titanium road machines, is created from 3Al/2.5V (3% aluminium, 2.5% vanadium) alloy tubes.
Instead of them being welded together where they meet, the Fusion uses investment cast sections (from 6Al/4V titanium alloy) for the head tube, seat cluster, bottom bracket shell and dropouts, with the tubes welded to them. This results in great stiffness, and it also allows for the smooth finish you see where the seat tube meets the top tube – not a shape you'll normally see on a metal bike.
Reilly has also embraced hydroforming to shape the tubing to meet the performance required in terms of stiffness and comfort – as well as aesthetics, of course. The dropped seatstays with their elegant curves are a prime example, or the box section down tube.
Elsewhere, the Fusion carries off that classic raw look that only a titanium frame can. The unpainted tubing can be returned to new with just a bit of a buff up, and the little welding details for the water bottle bosses look very well finished indeed.
With performance in mind, those are the only bosses you'll find – there's no provision for mudguards or rack. That's just not what this bike is all about. That said, if you want to go long there are plenty of frame bags on the market, and the comfort and ride quality of the Reilly will definitely let you cover some big miles.
Like many brands, for 2022 Reilly has hidden all of the wires, cables and hoses inside the frame and fork; they enter through the stem and down into the frame via the headset, revealing themselves at whichever component they are mated with via neat exit points. It gives a very clean look.
If you need access to them, it's under the bottom bracket via a neat little titanium door that is screwed into place.
Wheel retention is as you'd expect – 12mm thru-axles front and rear – while the callipers are flat-mount.
Our test model is the standard decal option of brushed black, with mirrored or custom anodised costing £250 extra.
The original owner also gets a lifetime warranty.
As always, Reilly has a detailed geometry table on its website for all five sizes, from XS up to XL. Our medium sits bang in the middle, rocking a 547mm top tube, 150mm head tube, and 510mm seat tube length.
The head angle measures 73 degrees, with the seat angle at 73.5 degrees.
The wheelbase is 982mm, while the chainstays are 414mm in length throughout the sizes. The fork rake is 43mm, and the bottom bracket drop is 72mm.
If stack and reach is your thing, you are looking at 555mm and 382mm respectively.
Reilly's website offers the Fusion in three builds – Shimano Ultegra Di2 in 11-speed or 12-speed, or Dura-Ace Di2 12-speed.
We have the middle option: the latest Ultegra D12 offering, 12-speed R8170.
As you can see from Liam's review, the performance is pretty exceptional and it offers ever so slightly smoother shifting than its predecessor, with better braking in terms of progressive feel.
The shifters are also now wireless to the battery, and I'm a big fan of the new hood shape. It's very comfortable while offering a natural shape for grip.
If you want the full information on the groupset then definitely go and read Liam's review; if you aren't that bothered about the details, I'll just say that the shifting is fast and crisp, and the braking is awesome.
At the front end, the cockpit if you like, you'll find Deda's latest DCR version of the all-in-one Alanera handlebar/stem, with this one capable of directing two brake hoses and electronic shifting wires completely internally into the frame and fork. I reviewed a previous version back in 2018.
It's not a cheap addition to the Fusion, but I do like the hand position options, with the flat top section give a wide platform for comfort when cruising along.
It is a stiff handlebar, but the ride quality of the Fusion's frame and fork offset that.
It's not often I talk about bottom brackets as part of the finishing kit, but when Reilly co-founder Neil Fitzgerald took me through the Fusion in detail, I could tell he had a real passion for the engineering behind the design of the SN-Vitae Module 47 unit.
It fits frames that accept threaded T47 bottom brackets, but the design is slightly different. The website is definitely worth a look.
The seatpost is a D-shaped design in carbon fibre which is clamped inside the frame via an internal wedge system.
Sitting atop that is a Reilly-branded carbon-railed saddle. It's quite long and slender – I've found myself moving towards more 'stubby' designs as late, but I still found it to be highly comfortable, the shape and minimal padding working whether you're on the hoods or in the drops.
As with the other components, you have a selection of wheels to choose from. The base model has a DCR x Reilly, 37mm-deep carbon fibre set, but our test bike is running wheels from Strada, its Carbon Performance Aero Discs at 55mm deep.
This is a lovely wheelset, very tight and light, plus the wheels have that all-important 'swooshy' sound that everybody knows is worth at least 20 watts!
Reilly fits Continental's GP5000 tyres as standard, and they are a great option. I've ridden countless versions of them, both tubeless and standard clincher, and they are some of the best performance tyres on the market.
Rolling resistance feels great and the grip of the supple compound is brilliant in the bends.
The base price of the Fusion with Shimano Ultegra Di2 11-speed, 37mm-deep carbon wheels, and FSA ACR Stem/Energy Compact Alloy handlebar is £7,499, with a £3,000 deposit reserving your place in the build queue.
With our upgrades to the latest Ultegra Di2, the Strada wheels and Deda cockpit, that pushes the price up to £8,699.
That's a big old price tag.
Saying that, the Moots Vamoots that I rode back in 2020 was a similar machine (investment casting aside), offering a performance ride that could match carbon fibre but with that supple edge that only titanium can deliver.
An Ultegra Di2 version of that frameset is currently £6,500 (etched titanium; £7,000 for brushed titanium); a Fusion frameset will set you back £3,999.
Mason's Aspect is a slightly different beast to the Fusion, but it has a very sporty edge to it that you might not expect. While it isn't quite as performance orientated as the Reilly, I can see similarities in the engineering and passion behind both designers. Also, the Aspect is one of the benchmarks when it comes to build quality, being handmade in small batches in Italy, although I'd say the Fusion is also of a very high quality.
So, it's pricey, but I wouldn't say that the Fusion is overpriced, especially considering that the investment casting of the 4AL/6V components adds to the cost.
The Fusion is a stunning bike, not just in the way it looks but the way it rides. To all intents and purposes it is a race bike; it rides like one and it handles like one. If you want the performance of a high-end carbon fibre machine, but have a hankering for metal then the Reilly needs to be on your list.
With all of its stiffness it still retains that beautiful titanium feel, and that is what makes the Fusion special to me. It's a bike you can hammer the life out of when you feel like it, but when you don't want to, it is also such a pleasure to ride.
Excellent bike with the performance and looks of carbon but the stunning comfort and longevity of titanium

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?
From Reilly's website:
Neil FitzGerald, Reilly Co-founder, says of the launch: 'Reilly's Fusion is spearheading the titanium road revolution. It symbolises an exciting time for us, marking a new chapter as we build on our framebuilding heritage, while continuing to innovate to offer all customers their dream ride and put the individual back into the bike.
'We have raised the bar again for road adventurers to create a truly cutting edge bicycle frame to enjoy the great outdoors, whether that's planning an ultra endurance road trip or sleekly navigating the daily commute.'
The Fusion takes a step back from being a full-on race machine, but it does that without sacrificing performance thanks to the stiffness of the titanium frame, which also delivers great comfort levels alongside that given by the geometry.
Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options
The Fusion starts at £7,499, with possible upgrades to groupsets, decals, wheels and bar/stem combos.
Frame and fork
Tell us about the build quality and finish of the frame and fork?
It's a stunning looking machine, with absolutely seamless transition between the investment cast parts and the main tubes. The attention to detail is amazing.
Tell us about the materials used in the frame and fork?
Frame: Investment cast 6AL-4V titanium head tube, seat cluster, bottom bracket shell and dropouts, with 3AL-2.5V tubing.
Fork: Carbon race fork with internal front brake hose routing
Tell us about the geometry of the frame and fork?
The geometry is aggressive enough to allow a fast riding position and for the Fusion to feel nimble and fast, though the front end brings stability, and a bit of neutrality, meaning you don't have to be a seasoned racer to master the handling at speed.
How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?
The stack and reach figures give a riding postion that can be aero without being too aggressive. The numbers are in the right ball park for the frame size.
Riding the bike
Was the bike comfortable to ride? Tell us how you felt about the ride quality.
Surprisingly, considering how stiff the frame is, the Fusion still retains that lovely titanium smoothness and comfort.
Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?
The Fusion has great levels of stiffness, especially at the front end and around the bottom bracket area.
How did the bike transfer power? Did it feel efficient?
Power transfer feels great, thanks to the stiff frame and fork, the spread of the Ultegra gears, and a reasonable weight for the whole build.
Was there any toe-clip overlap with the front wheel? If so was it a problem?
How would you describe the steering? Was it lively neutral or unresponsive? A great balance of quickness in the steering without being twitchy.
Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?
The handling is great, very direct, and the frame/fork combo gives loads of feedback which allows you to have fun in the bends.
Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?
I got on well with the Reilly branded saddle and the Alanera integrated handlebar and stem offers comfortable hand positions.
Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?
There was no flex at all from the deep-section carbon fibre wheels, or the handlebar.
Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?
The wheels cut through the air well.
Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?
This newest version of Ultegra Di2 is faultless in both its gear changing performance and braking capabilities.
Wheels and tyres
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?
The Strada wheels are smooth rolling and give an aerodynamic boost above around 23mph, which certainly helps the Fusion to feel sprightly.
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?
Continental's GP5000s are some of the best road tyres out there offering exceptional levels of grip and rolling resistance. More importantly, their suppleness doesn't mute the excellent feedback you get from the frame and fork.
Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?
A top-end bike deserves a top-end build, and this is what you are getting here.
Did you enjoy riding the bike? Yes
Would you consider buying the bike? Yes
Would you recommend the bike to a friend? Yes
How does the price compare to that of similar bikes in the market, including ones recently tested on road.cc?
It has a similar ride style to the Moots Vamoots, but with a frameset that is around £2.5K cheaper, and it stands up well on price to the Mason Aspect, too. That's a slightly different machine in terms of performance, but a benchmark when it comes to quality.
Use this box to explain your overall score
It's excellent. The ride quality for such a stiff bike is truly stunning, and the finished product looks absolutely beautiful too.

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
