At road.cc 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.
Good scores are more common than bad, because fortunately good products are more common than bad.
The new Focus Izalco Max Disc is based loosely on the regular Izalco Max carbon fibre race bike, as used by the Ag2r professional outfit for the past couple of seasons. This one's got disc brakes, though, which are all the rage in the cycling world right now.
I've been riding it for some time now, following a first ride at the Italian launch event last summer, and it makes a strong case for that title. The tweaks to the frame and fork to accommodate the disc brakes are superficially quite minor, but bring some significant benefits: a more comfortable ride, space for wider tyres and handling that is direct and crisp. Oh, plus the extra control of the hydraulic disc brakes.
There are two versions available. The lightest, and most expensive, is a model with a SRAM Red drivetrain and hydraulic disc brakes, and Zipp 202 carbon fibre wheels. It weighs a claimed 6.8kg but costs £4,699.
More affordable is the Shimano Dura-Ace version on test here, which mixes Shimano RS805 hydraulic disc brakes with a Dura-Ace rear mech, Ultegra 11-28 cassette, FSA SLK Light Carbon 52/36 chainset, DT Swiss R32 wheels, 25mm Schwalbe One tyres, and a Fizik bar, stem and saddle. It weighs 7.5kg and costs £3,299.
Okay. Are you sitting comfortably? It might share the same name, and very similar aesthetics, of the regular Izalco Max, but the new bike has some significant differences. Impressively, the Max Disc frame weighs a claimed 790g for a size 54cm, with a fork weighing 320g. Those are good numbers for a non-disc carbon race frameset, let alone one beefed up for disc brakes.
The frame combines very modern details with one very conventional one – externally routed gear cables. This is deliberate: routing the cables externally makes the frame 50g lighter, and it also provides easier maintenance for the Ag2r team mechanic. But any home mechanic who has struggled to replace an internally routed gear cable will appreciate this too. Once fitted, hydraulic hoses should never need replacing, so Focus has routed the brake hoses inside the frame and fork.
Shift your attention to the wheels and we find the company's own RAT (Rapid Axle Technology) axles. They're bolt-thru axles using a large diameter axle (15mm front, 12mm rear) that locks into the opposing closed dropout. Unlike most other thru-axles that are threaded into the dropout, much like a conventional quick release, the RAT system requires a simple 180-degree turn to lock a T-bar on the end of the axle into the dropout.
I used the RAT system on the Focus Mares cyclo-cross bike I tested last winter, and it took me just a few moments to familiarise myself with the axle system again. It's wonderfully easy to use. I'd like to see this become standard on all bikes that use thru-axles. I can remove a wheel with RAT quicker than I can a regular quick release, for those overly concerned about slow wheel changes being a problem on disc road bikes.
The disc brake callipers are fixed onto the frame and fork using the latest Flat Mount design. Put simply, it's a lighter and cleaner mounting system and looks likely to become the standard that most manufacturers adopt.
Disc rotor rub has been an affliction that has ruined some early disc brake road bikes, but the Izalco Max doesn't display a hint of rotor rub at all. Admittedly I'm no heavyweight, but pushing and pulling on the handlebar as hard as I could on the climbs didn't force any unwanted flex in the fork.
Yes. The chainstays are 10mm longer than the standard bike, producing a 998mm wheelbase. That's still short compared with endurance bikes but longer than most race bikes. It's a small difference, but importantly one that doesn't ruin the performance. If anything, it enhances the ride, with a slightly more stable characteristic.
Modern race bikes typically have short chainstays, in the region of 405mm, give or take a few millimetres. This provides the snappy and agile handling that racers favour. Add disc brakes to a frame with short chainstays and, because of the wider rear axle (to squeeze a disc rotor in between the dropouts), you can encounter chain line issues, leading to mis-shifts, even dropped chains. To counter this, Shimano recommends a 415mm minimum chainstay length.
In developing the S-Works Tarmac Disc I tested at the end of 2014, Specialized didn't follow Shimano's advice. Instead, it developed a quite ingenious workaround, allowing it to keep the short chainstays and identical geometry of its regular non-disc Tarmac. But it had one critical downside: you had to use the Roval wheels.
Focus has taken a more pragmatic approach with the Izalco Max Disc. It has followed Shimano's advice and simply lengthened the chainstays by 10mm. That's it, no specially modified hubs or special wheels required. Racers might be fearful that the 10mm change to the wheelbase will ruin the handling, but Focus is confident the change won't impinge on the performance and handling of the road bike, and if anything will actually be a benefit.
They do. The Izalco Max Disc comes fitted with 25mm tyres, which are rapidly becoming the new 23. Wider tyres help in the comfort department too, of course. The stock Schwalbe One tyres are an excellent choice and inflated to 5 bar (72psi) provide all the smoothness and grip you could want in a fast race bike, without it ever feeling soft or vague at higher speeds.
Better than that, there is space for up to 28mm tyres. To verify this, I tried some. They fit easily, with decent clearance between rubber and carbon. You might not want to tackle a muddy-cobble race, but they do fit.
With the bigger tyres, the ride is improved, with a marginally more comfort yet little discernible impact on speed. The bike did feel slightly less nimble, probably because of the extra weight of the wider tyres, and low-speed acceleration was more muted.
Aside from the benefits of disc brakes, giving the Izalco Max the disc treatment has enabled Focus to rework the shape and carbon fibre layup of the seatstays. This, along with the removal of the now redundant brake bridge above the rear wheel, has freed up the seatstays to be refined to provide the bike with improved compliance over the non-disc version.
There's more. Focus has developed a new seatpost that is intended to further increase the comfort on offer. The Concept CPX Plus post, 27.2mm in diameter and 195g on the scales, is entirely made from carbon fibre, and a hollow section below the clamp mechanism is intended to absorb vibrations.
Seated comfort is excellent, no doubt enhanced not just by the seatpost but also the wider tyres and the changes to the frame. It's impressively smooth, not just for a race bike, but even compared with bikes that are designed expressly to be comfortable. Here's a race bike that doesn't beat you up after an hour or two around the Cotswolds lanes.
In fact, this is what is most striking about the new Izalco Max Disc: how it combines the smoothness of an endurance bike with the speed of a race bike. It simply soaks up bumps in the road, yet it's as fast as any other race bike on the market.
It's very refined, there's no choppiness, even on the most scarred road surfaces. From slow speeds to high tempo riding, the Focus provides such composure that you sometimes forget you're on a bike designed for racing. In fact, I'd go as far as saying it's smoother than some so-called endurance bikes.
Yes, this is a bike designed for racing. That much is clear when you get into a fast pace line, or in the way the Focus responds to attacking sprints and surging hill climbs. It's no slouch. The racing DNA is easily unmasked when you get the bike up to speed and inject some watts.
It doesn't always 'feel' as fast as some other race bikes, simply because the bike is filtering out a lot of the harshness, especially at higher speeds. But a glance at the computer always reveals you're travelling quicker than you thought.
There's a lovely balance to the Focus. In the corners, the Izalco Max Disc reveals direct steering, light and communicative enough to allow minute adjustments mid-corner. There are no quirks. It's light enough to go toe-to-toe with other non-disc road bikes, on the flat or in the hills. It's a very capable bike. More than that, it's a cool bike.
The changes to accommodate the disc brakes have only served to provide an astonishing level of comfort with no impact on the bike's speed, acceleration and handling. It's one of the very best disc road bikes I've ridden, and if this is a taste of what's to come as more race bikes are given the disc brake treatment, I can't wait to see and ride them.
The Izalco Max Disc is available in seven sizes, from 48cm to 61cm. The 56cm I tested has a 565mm top tube and 160mm head tube, providing a reasonably low and stretched position with the stock 110mm stem. The wheelbase measures 998m with a 70mm bottom bracket drop and the head/seat tube angles are 73 degrees.
Pretty well, yes. The Shimano hydraulic brakes are easy to operate, with great lever feel, and there's never any fear that you might lock a wheel, even in the wet. Focus has combined a 160mm front rotor with a smaller 140mm rear. The idea is to provide more punch from the front brake, which is more critical to the actual stopping ability of the bike. It saves a bit of weight from the smaller rear brake rotor, too, which is placed under fewer demands than the front rotor.
Focus has combined a cheaper Ultegra 11-28t cassette with expensive Dura-Ace derailleurs. The cassette is going to wear out long before the mechs, and there's marginal weight difference between an Ultegra and Dura-Ace cassette. The gear range provides a good spread for high tempo cycling and is low enough for most climbs – this is no sportive bike, though, so the gearing isn't as low as you'd find on an endurance bike.
I found no issues with the DT Swiss R23 DB wheels, with a good level of stiffness apparent. I had no concerns with durability through the test period either. It's a tubeless wheelset, so it would be easy to make a future upgrade to tubeless; If I bought this bike, that is something I would look to do.
Focus has clearly cherrypicked a few components to hit the £3,299 price tag, but there's nothing at all wrong with the FSA SLK Light Carbon chainset. It's plenty stiff enough and the 52/36t chainrings are a good combination for racers and sporty cyclists.
The Fizik Cyrano R3 handlebar has a comfortable shape with shallow, easy to reach drops, and the Fizik Antares R5 Manganese saddle is reasonably comfortable. I'd rather have an Arione saddle personally. That would be an easy change.
There aren't a lot of choices if you want a properly racy road bike with disc brakes, and top of the list of the ones I've ridden is the Specialized S-Works Tarmac Disc. Does the Focus come close to rivalling, or even bettering, the S-Works Tarmac Disc? Both are right at the forefront of a new wave of disc brake-equipped race bikes, and while the S-Works manages to retain identical geometry to the regular version, it makes a serious compromise in wheel choice with its special rear axle arrangement.
The Izalco Max might have a longer wheelbase, but it's no detriment to the performance and handling, and the bigger tyre clearance, easy-to-use thru-axles and impressive comfort sees the Izalco Max just edge ahead.
Both are very good bikes, and if you're in the market for a proper race bike with disc brakes, you're not exactly spoilt for choice. But the Focus is easy to recommend. Anyone fearful that disc brakes might ruin a race bike need not worry.
Is the Focus Izalco Max Disc the ultimate disc brake-equipped race bike then? Right now, yes it is. There's very little competition and it's a massively exciting bike to ride with unsurpassed comfort that belies its racing credentials.

More comfort with the new Concept CPX Plus Post
Speaking of comfort - at FOCUS, we love to consider each and every aspect of the bike – including the oft-overlooked seatpost. Our new in-house developed CPX Plus carbon seatpost is an integral part of this comfort concept. The seatpost's specific carbon layup structure in combination with its diameter of 27.2 mm results in an efficient suspension, that along with the frame, absorbs small bumps. The CPX Plus Post will be available in a road bike version with 25 mm setback (there is also a version for mountain bikes available with 0 mm setback). Comfort isn't the only advantage of this seatpost though – at only 195 grams it's also pretty light!
Different sizes – same riding experience
Humans are not made equal in terms of body dimensions. In order for every rider to experience the same performance aboard a FOCUS carbon bike, FOCUS engineers developed a solution:
SSPS – Stable Stiffness Per Size. The theory behind it is simple: bigger frame sizes consist of longer tubes, which are less rigid due to their increased length. At the same time, taller riders are usually heavier and produce more power than smaller riders and consequently need a stiffer frame.
To make sure riders with different heights and therefore different power profiles are fitted on frames that match their characteristics, the tubes' cross sections, geometry, as well as the lay-up of each FOCUS carbon frame have been adapted for each size. Larger sizes feature a stiffer lay-up for the down-tube for optimal power transfer, while smaller sizes have a unique carbon layup to make sure lighter riders experience the same vertical compliance and stiffness. This gives all riders the same riding experience.
Frame and fork
Tell us about the build quality and finish of the frame and fork?
Very high quality build with nice attention to detail.
Tell us about the materials used in the frame and fork?
Full carbon fibre frame and fork, 790g for a size 54cm, and uses the company's Stable Stiffness Per Size, which sees each size frame optimised.
