Breaking the Darkness: DIZO EOS Road Bike Build and Review

dizo eos shimano roadbike review

New Bike Day is often an thrilling day, though with the DIZO EOS street bike it was totally different because first it wanted full bike build. This included drawback solving and incremental fine-tuning until it was truly New Bike Day. DIZO… who are they? DIZO is the brand new own-brand of the Taiwanese producer Superior International Multitech (AIM) who provide worldwide brands with bikes, golfing gear as well as supplies for airways.

Within the biking world, the small print of the Asian (OEM) manufacturing associate for the western manufacturers tends to be stored underneath wraps. Whenever you delve a bit deeper you might discover a connection between AIM and famend manufacturers resembling Bianchi, Cannondale, Dedacciai, Look and Specialised. With robust credentials and 30 years of expertise, AIM the established DIZO as their own-brand in 2016 and now they are in search of to grab the attention of cyclists globally.

For evaluate on Bicycles Network Australia, a carbon fiber frame with forks was provided whereas the groupset and elements have been purchased and assembled to finish the construct. This frameset retails for round AUD 3,700 and the entire bike costs between AUD 5,450 (Shimano Ultegra mechanical R8000 with Hawkvi alloy rims) and AUD 7,150 (Shimano Dura-Ace Mechanical with Hawkvi Carbon rims). There’s at present no Australian distributer so tax and import duties will apply though full bikes are tariff-exempt.

This evaluation walks-through the DIZO vary of street bikes, sizing choices and meeting (outlining points and problem-solving) before detailing the journey expertise. Most riders would buy a totally assembled bike (relatively than just the frameset), on this case it’s worthwhile studying the small print on frame sizing and development, but you possibly can skip the DIZO EOS bike meeting and proceed to the Journey Evaluation.

Sizing up the DIZO EOS

DIZO supply four street bike models, the masculine M8 is described as a hill climber while its sister, the EOS, is “designed to seize the irreplaceable feeling of conquering a peak via the mist and cloud at dawn”. The S6 model is accessible in a couple of colour variations (R, V, RockSummit and Ego) and eventually there’s the GF6 model with a curved top-tube design, a method that appears vaguely recognisable (I’m positive I have seen this frame design underneath different brand names).

Beyond the colour schemes, the variations between the models isn’t notably apparent and to broadly categorise the range of street bikes, I might say that the S6 fashions are pitched as performance bikes, the M8 and EOS are hill climbers and the G6 is the consolation bike.

After spending time wanting intently at the geometry and evaluating fashions, I realised that the EOS and M8 bikes have the identical frame and simply differ optically. The gray / pastel EOS is pitched in the direction of ladies and is on the market in sizes XS, S and M (ca. 50, 53 and 55cm) whereas the stealth black M8 is focused in the direction of males with body sizes S, M, L and XL (ca. 53, 55, 57 and 59cm)

I opted for the EOS to assessment on Bicycles Network Australia as I used to be drawn in the direction of the color as it is totally different to most of the types obtainable available on the market immediately. In an age the place males can put on Rapha biking package with pink highlights, the notion of gender unique colors is old style. The M8 is similar, simply with the totally different colour so if this fits your fashion, the tech and journey particulars of the EOS are relevant.

The phrase “Break the Darkness” is written on the highest tube and I feel this can be a fairly good metaphor for the EOS on a couple of ranges. From instance confronting a few of the conventions of colour schemes to cycling at daybreak because the sunrises. But in addition a shift to the driving experience moderately than simply the tech.

For the body measurement I chosen the most important obtainable EOS mannequin, the dimensions M with a 549mm headset to seat-tube measurement (and 515mm Backside Bracket to the top of seat tube). Cross-checking my own street bike and bike match geometry confirmed that I might make the required adjustments and dial-in the bike fit, for instance, I exploit a shorter stem to provide me the right attain.

In case you haven’t already spotted it, there are not any disc-brake models in the whole lineup. In reality, this is shocking and might be a deal-breaker for some individuals. All the critical brands have adopted disc brakes on their mid and high-end street bikes and it seems like a very loud clock is tick tocking. DIZO confirmed they’re on the case and early next yr they will be introducing new frames with disc brakes to their lineup.

DIZO Frame Development

The Japanese provided Toray T1100 carbon fiber is utilized in for DIZO bikes. This detail is used as a badge of honour by the brand to spotlight the frame high quality. As compared with the T800 carbon fiber, T1100 has extra carbon strands and the resulting material advantages are larger power and a better modulus of elasticity. In other words, it is nicely suited to delivering the required body power and adaptability. It ought to be famous that different grades of carbon fiber are also used for the body development.

dizo eos frameset review

For the carbon fiber format (design and placement of the carbon sheets in the course of the moulding), Finite Factor Analysis (FEA) is utilised and this includes pc simulations to test the materials and development in the course of the design and engineering. As a rider, I like figuring out that the body design is a thought-about process, however two different details in the DIZO bicycle frame development captured my curiosity.

carbon fiber t1100

The primary element is using Carbon Nanotubes which is intently associated to that marvel materials, Graphene. A Carbon Nanotube is a microscopic tube shaped from carbon atoms and is famend for its power.

There’s loads of science and plenty of advertising appropriation of these ‘super supplies’. DIZO tap into this by including carbon nanotubes into the resin which bonds the carbon fiber. They are saying the advantage is that much less resin is required (i.e. lighter) however it additionally helps to increase desired properties akin to frame power. Driving the bike, I can’t understand this know-how in any respect. I like the sound of it, but in apply I simply should put my religion in the model that they know what they are doing.

The other detail additionally ‘invisible’ if you experience this bike but for my part it is extra essential. DIZO use an X-ray Detection Course of for quality control and check each body earlier than it leaves the manufacturing unit. Through the development of a carbon fiber bike, there are lots circumstances by which a carbon fiber body and elements might be compromised and the resulting flaws can remain hidden… even on high-end bikes. The X-ray Detection provides peace-of-mind.

DIZO EOS Bike Assembly

Most bike consumers want to buy an entire bike which is often cheaper than buying a frame-set and the elements individually. At present the EOS and M8 full bikes are available for purchase with the mechanical Shimano Ultegra (R8000) or Dura Ace (R9100) groupsets though not with Di2 electronic shifting.

For this evaluate, the operating gear was not provided and the elements, construct and instruments have been my duty. I bought the mechanical Shimano Ultegra R8000 groupset (rim brakes) together with an assortment of fairly priced elements to complete the build.

Out of the box, the body and fork have been properly packaged and the graphics and quality of the finish is superb. The matt grey end is adorned with glossy sections of pastel inexperienced, blue and pink. The matt finish appears good although muck and dirt doesn’t wash off quite as simply as on a glossy bike body.

The dropouts for the front and rear wheel are utterly carbon and the frame and fork take commonplace skewers.

A notable function have been the plastic inserts on the highest tube for the cable routing which have been nicely designed and could possibly be utterly removed throughout cable set up and then nicely locked into place.

I had the prospect to peak inside the body and will see that the carbon fiber moulding was fairly clean, notably around the bottom bracket. The headset had some creasing and I fished out a small piece of paper from the headset which was in all probability a small sticker from high quality control.

General, the EOS frame seemed to be nicely built and properly finished though I recognized a number of small details where there’s room for improvement within the body design which will probably be addressed in this section overlaying the bike build and meeting.

I recorded a frame weight of 881 grams, 30 grams over spec, while the fork was 340 grams, 30 grams beneath spec (1.2 kg complete). It’s a very respectable weight and along with the headset bearings and expander plug (118 grams) it tallies up to 1.3kg which is an effective basis for constructing a fairly lightweight bike.

The top end result for me was a motorcycle weighing around 7.9 kilograms (incl. pedals and aluminium wheels) which is outstanding contemplating I used used numerous aluminium elements and weight was not my precedence. With a bit additional cash for lighter elements, you may retain the Shimano Ultegra mechanical groupset and comfortably attain 6.9kg.

Bottom Bracket Tripeak Twist-Fit

The first hurdle I confronted assembling the EOS street bike was the bottom bracket installation. A suitable Tripeak BB86 Bottom Bracket was provided which was each a blessing and a curse. The great half; I didn’t have to think about widths, sizes and compatibility, the provided Tripeak Bottom Bracket with ceramic bearings was suitable.

This specific mannequin is designed to fit backside brackets of different widths. The Tripeak Twist-Fit bottom bracket system is just like a press-fit backside bracket but as an alternative of just pressing it into place, it then screws tight… so is a hybrid answer. The thought is that the threaded assembly eliminates the infamous creaking and reliability issues of press-fit backside brackets.

To put in the Twist-Fit BB, not only do you want a normal set of backside bracket installation instruments to ensure the 2 sides are completely aligned, you also have to purchase a particular 16-notch adapter for this sort of exterior bearing bottom brackets.

There was an sudden twist putting in the Tripeak backside bracket and I learnt one thing new. The Twist-Match bottom bracket fastens anti-clockwise… the improper approach. I learnt that numerous giant torque wrenches only register torque clockwise?

This caught me abruptly and you need to examine your torque wrench before assuming otherwise. Some giant torque wrenches reminiscent of the massive Park Software TW 6.2 (10 – 60Nm) which prices around $250 are bi-directional.

For the bottom bracket set up I used to be primarily alone to seek out documentation and research details such as the required torque (30Nm). I needed to determine and then buy the special bottom bracket adapter and the match of the adapter wasn’t fairly as comfortable as I anticipated. Assembling a motorcycle by discovery isn’t plain sailing and at occasions it felt as though I was going towards the present.

Taking time, care and endurance to put in the underside bracket, the end-result was a hit, the cranks match properly and whereas driving there have been no creaks, groans or issues.

Headset and Slicing the Steerer

With my bike-fit geometry as a guide, I sourced an appropriate 3T stem and handlebars, opting for aluminium quite than carbon. FSA headset bearings and expander plug have been provided and I had spacers to realize the suitable peak which means I used to be prepared to put in the headset and minimize the carbon steerer on the full-carbon fork.

‘Measure twice, reduce as soon as’ is the golden rule, though I measured a dozen occasions to be completely sure before chopping. Although I am keen on the optics of a wonderfully flush stem, I went for a 5mm spacer on prime of the stem which is a usually accepted as an excellent strategy to make sure the absolute best clamping match.

As a lot as I tried, after slicing the carbon steerer and putting in the fork, it wasn’t attainable to get a ‘wobble-free’ headset. On paper, the installation was right from the headset assembly to torque for the expander and prime cap in addition to the stem set up. After utterly reinstalling the fork and headset quite a few occasions with out success, I enquired with DIZO who prompt a 10mm spacer somewhat than the 5mm spacer.

5mm spacer headsetA 5mm spacer on prime seems to be good, but the fork was not wobble free.

I didn’t want this additional peak, the steerer had been measured appropriately for slicing, I also cross-checked the FSA documentation, two street bike upkeep books and the collective knowledge of the web to verify all the things had certainly been installed appropriately.

Unfortunately, the solution for a wobble-free headset on the EOS was to make use of the instructed 10mm spacer fairly than 5mm on prime of the stem. Within the DIZO catalogue, pictures of EOS and M8 reveal a 10mm (or higher) spacer on prime of the stem so I’m wondering if that is an inherent concern.

Groupset: Shimano Ultegra R8000 Mechanical

Shimano Ultegra is a wise, efficiency orientated groupset and my selection for the DIZO EOS. Electronic Di2 shifting would have been nicer and regardless of the advantages in installation and shifting, my finances constraints made me accept the mechanical Shimano Ultegra groupset for rim brakes.

handling dizo roadbike

Jagwire Professional cables (with Matt black outer casing) have been used for the brake and shifting cables and pre-installed plastic cable guides helped immensely for fast inner cable routing. At my fingertips on an iPad, the obligatory Shimano Supplier Manuals for this groupset have been loaded up. Because it was a new set up slightly than a alternative, I had to make a couple of selections about cable routing. The gear cable entry port on the frame for the interior routing is, for my part, suboptimal.

The cable entry port is on the downtube and awkwardly positions the two shifting cables shut together. This is not a problem in itself but you also have to think about that the cables want clean curves (and not sharp bends which may influence shifting). Plus the cables need sufficient size in order that they don’t seem to be overstretched when the handlebars are turned. In consequence, I felt that the installed gear cables have been unnecessarily lengthy and untidy. Although there isn’t a useful drawback, better placement of the cable entry ports would have allowed the set up of shorter cables and thus given the bike a cleaner look.

On the subject of a clean set up, digital shifting negates external shifting cables utterly. DIZO provide a canopy for the port and this bike naturally lends itself to Shimano Di2 (or should you favor, SRAM eTap or Campagnolo EPS).

The other set up challenge was the tedious setup of the Ultegra R8000 front derailleur. The R8000 collection is new to me and the front derailleur is especially fiddly to setup appropriately. A selected situation was the place of the brazed-on entrance derailleur mount on the EOS body. Inside the entrance derailleur mechanism there is a help bolt that’s designed to the touch and brace towards the frame or the braze-on. Shimano provide ‘backup plate’ which is designed to guard carbon frames. I found that the help bolt touched the body precisely between the braze-on and backup plate. If the braze-on was a couple of mm larger or decrease, the installation would have been cleaner.

A nice function was the included chain-catcher that forestalls the chain from ever by accident slipping off the small chainring and saving you from a damaged body. After the nice tuning the gears and some check rides, the top outcome was a exact and ergonomic groupset that complimented the DIZO EOS.

I purchased the mechanical groupset with the same gearing often specified on the entire EOS and M8 bikes. The Shimano Ultegra groupset came with a 50-34 chainring which might be described as compact and an 11-34 (11-speed) cassette. In other words, lot’s of straightforward gears for hill-climbing however at the cost of excessive speeds.

The gear ratios have been an enormous step away from my traditional 11-28 (10-speed) cassette with 53-39 entrance chain rings and I ultimately regretted this as a result of I missed out on quicker downhill speeds within the prime gears. A comfort is that the inside and outer chainrings may be modified (they need to be paired).

Bottle Cages and Bicycle Bits

DIZO proved two minimalistic black carbon fiber bottle cages which suited the frame nicely and labored nicely. I decided on a dominantly black theme when choosing the color of all the elements as a contrast to the grey and pastel coloured frame. DIZO offered transparent ‘frame protector’ stickers which is thoughtful. The Jagwire shifting cables got here with rubber protectors that have a tendency to mark the body so the clear stickers have been strategically placed at the ‘touch factors’ on the headset. The chainstay on the drive-side is particularly vulnerable to grease and an extended protective sticker was applied.

DIZO included a carbon fiber card (the dimensions of a credit card) which has the identify of the body designer and the serial number for the frame. I like this personalisation because it suggests accountability and individuality. A small multitool was additionally provided, a nice touch however it was comparatively heavy and lacking some essential tools I like akin to a chain-breaker.

I topped-off the handlebars with some black Dedacciai handlebar tape and in addition purchased a suitable seatpost from Dizo which turned out to be aluminium tubing with some carbon fiber elements for the locking mechanism. The locking mechanism seemed to be rudimentary and I’m still not satisfied, however it hasn’t creaked or complained following months of driving and a few saddle swaps.

For the saddle, I opted for the Prologo Nago Evo Pas which is my regular saddle but in addition rode with the Scicon ELAN saddle which is just a little wider and shorter than common street cycling saddles.

I tested the EOS with deep 50mm carbon fiber wheels (FSE) in addition to aluminium alloy rims (Swiss Aspect PION). Broad 28mm Pirelli P-Zero street biking tyres have been used and one curiosity was that the spews (rubber hairs) on the tyres marked the body while I used to be driving, so I reduce off the spews and it was resolved.

DIZO EOS Journey Evaluate

My driving place from my Big TCR street bike was replicated on the DIZO EOS. Whereas the Big feels fast and edgy, the EOS is compact and cozy. The wheelbase of the EOS was about the same because the Big (98cm) however as compared, the EOS felt like an agile climbers bike.

The bold, rounded tubing on the frame sends a clear message that it isn’t an Aero bike bike however on the street it was right at residence with strong tempo and good handling with out being too pushy or aggressive.

Although it lends itself to being a hill-climber with the compact gears, I discovered that I not often used the underside three or 4 gears in the cassette. Solely when the going will get actually robust and the gradient creeps over 10% did the extra gears begin to make sense for me. Racing down the opposite aspect, I shortly ran out of gears. For me, compact gearing was not the best choice.

Numerous riders nevertheless will respect the compact gearing, notably new riders together with cyclists who experience with a more steady pace. For giant Alpine climbs with enduring switchbacks that ascend into the clouds, this gearing can be a aid.

Each the deep 50mm carbon fiber wheels and the aluminium wheels matched the bike optically and functionally. The carbon fiber wheels have been quicker and offered a stiffer journey whereas the reliable aluminium wheels complimented the snug nature of the bike. From the outset, I felt regular on quick, curvy descents. The bike remained secure even when faced with poor street surfaces and what it lacked in prime speeds, it added in its confident and reliable dealing with.

In case you attempt sprinting, the bike responds and rapidly picks up velocity. I felt it nonetheless remained snug and secure as it accelerated. I really appreciated this bike-feel as a result of you can also make a move and the bike can pay along but it isn’t as edgy and aggressive as a thoroughbred racing bike which may ship raw, unfiltered energy surge. It is missing a couple of prime gears to be a competitive finish-line sprinter although you’ll be able to go for a breakaway on the hills and drop your driving bunch.

Soaking up the vibrations and street noise, the body is at residence on longer rides and hill climbing where comfort is necessary.

Is DIZO for you?

A number of street bicycles are pitched in the direction of clients as ‘performance machines’ designed to provide you a technical benefit over your counterparts. A few of these things could make a distinction if you find yourself competing but many other options are solely marginal if just take pleasure in getting out and driving your bike. On this respect, DIZO are promoting reliability – a properly made street bike which you could trust.

For longer distances, I discovered that the EOS rode properly. Whilst my legs turned sore and my body exhausted, driving felt good and worry-free. Gran Fondo… no issues. Sydney to the Gong journey… let’s go. Even for multi-day tours and charity rides, you get the best degree of efficiency without it getting in the best way of a very good bike journey.

The EOS (and by default, the M8 as properly) will hold their own in bunch rides although the gearing will attain its limits if it begins to get really quick. The compact cranks nonetheless supply adequate vary to permit you to settle into the cadence and pace that fits you and let you deal with these hills and mountains.

For younger ladies moving into cycling, the geometry is snug (neither too relaxed or too aggressive). The lacking disc brakes and electronic shifting choices will exclude bike riders who would in any other case find the EOS, M8 and S6 fashions engaging.

On pricing, the DIZO EOS and M8 framesets and full bikes are positioned in a better worth category than comparably spec’ed bicycles from Big, Merida and Specialised. For instance, the EOS and M8 frameset retails for $three,700 (before import tax and obligation) which is $400 more than the Big TCR Advance SL. The DIZO frameset consists of the Tripeak backside bracket with ceramic bearings whereas the Big frame is with out.

I have no doubts concerning the quality of the EOS body and the journey dealing with, as a young brand (like Swift Carbon and Factor), DIZO will need to work exhausting to point out riders why their street bikes are higher than widespread brands.
