Review: Trek Domane 4.5 – A High-End Frame and Smart Build Kit

While many brands have introduced “endurance” road bikes over the last few years, few have taken the idea to quite the extreme as Trek.

Trek Domane 4.5 – A High-End Frame and Smart Build Kit

The Domane was developed with considerable input from Swiss pro cyclist Fabian Cancellara , who is known for his steam-engine riding style, using his massive power output to crush cobblestones in the fabled Spring Classics. He is said to enjoy the bike so much that he rides it year-round, even in the Tour de France, choosing it over Trek’s racier Madone model.

The frame features the intriguing IsoSpeed decoupler , an ingenious system that separates the seat tube from the top tube and seatstays, and allows the seat tube to flex and pivot at the mounting point. If you stand next to the bike and put your weight on the saddle, you can see the seat tube flex slightly, but while riding it is imperceptible until you hit a bump.

A High-Performance Machine

Make no mistake: IsoSpeed is not a suspension system, and this is still a high-performance machine. If you’re expecting something akin to a suspension seatpost, think again. The frame’s ride quality is distinctly carbon—a muted road feel with less of that high-frequency vibration you feel from some aluminum frames, but still generally stiff.

Iso Speed makes itself most noticeable when crossing railroad tracks or other high-speed, sharp impacts that would normally require you to lift or shift your weight on the saddle to avoid being bounced. Not having to do that means you can keep your cadence smooth and the power high. The system seems so extreme some might think it’s a gimmick, but I’m convinced. Trek is as well—the technology will soon be adapted to its line of hardtail mountain bikes .

At the other end of the bike, the fork deserves some of the credit. It was developed with an asymmetrical steerer tube that is slightly thicker side-to-side than front-to-back, giving it a touch of compliance, but it never felt soft or shuddering.

The difference between the Domane 4.5 and the higher-end models is in the stiffness of the carbon fiber itself, and that this version uses a standard 27.2mm seat post rather than a seatmast that is integrated into the frame. I actually prefer the standard post, as it can be swapped for countless alternatives and provides an easy spot to clamp the bike in a work stand.

Trek’s DuoTap Hidden Speed

Other frame details include a spot for Trek’s DuoTap hidden speed and cadence sensor, an integrated chain guide to eliminate dropped chains and more generous tire clearance than most frames. It also has removable fender eyelets, so you can keep the clean look if you’re not using them. For an even smoother ride, you can ditch the tubes and set up the Bontrager Race wheels tubeless—another technology that is easy to dismiss until you try it.

It would be a mistake to write off the Domane as a “comfort” bike for weekend warriors. Despite accommodations for a smooth ride, it is as stiff and race-worthy as I could ask. Yet the slightly longer wheelbase makes it extremely stable, and it’s one of the few bikes I’ve ever plunged downhill at 40mph with a crosswind while still feeling relaxed. The fit adds to the comfort factor, as the slightly taller head tube gives you a more head’s-up position than Trek’s race bikes. Paired with a set of shallow-drop Bontrager handlebars , I felt great in each of the riding positions, an essential element of a long, comfortable ride.

Domane: Initial Acceleration is Direct and Instant

The adage “laterally stiff and vertically compliant” has gone beyond cliché to become something of a running joke in road bike circles. The notion that a bike can be a stiff-as-heck race machine and still be comfortable over rough pavement on long rides is not unlike a unicorn—a magical beast that surely can’t exist. But on the Domane, initial acceleration is direct and instant, with the massive, squared down tube and BB90 bottom bracket all but eliminating lateral flex.

Back in Issue #16 I reviewed the Volagi Liscio, which also features an unusual seat tube arrangement—the seatstays bypass the seat tube and connect to the top tube. While the Liscio was smoother than the Domane in a straight line, it can’t compete with the Domane in terms of power transfer and handling accuracy. The Domane makes no sacrifices in these areas.

The Shimano Ultegra build kit performed flawlessly, as I expected. The compact crankset paired with an 11-28-tooth cassette offers tons of range for tackling the steepest pitches. The 105-level brake calipers offer power to spare, as a single finger is often enough to bring the bike to a stop.

Hitting the street for less than $2,800, the Domane 4.5 struck me as a steal, considering the high-end frame technology and the smart build kit. While it will likely be pitched to riders looking for a high-performance ride for centuries and gran fondos, the Domane is a race bike at heart that won’t beat you up on the weekdays.

Rating (4.7/5.0)

Introduction

Is the once great “General” still as good as it was today? I think the 2016 Trek Domane 4.5 was very hard to get at the time, and even if you got it, you had to wait a long time to get it. However, now with the constant updates of Trek, it is no longer in production. However, it is a very classic road bike. Both performance and comfort are no problem today.

Next, I break down the 2016 Trek Domane 4.5’s uphill and downhill performance, key features, and components and specs for a breakdown, as well as how it compares. If you’re interested, stay tuned!

Trek Domane 4.5 Road-Uphill Review

Classics never go out of style. This 2016 Trek Domane 4.5 is still hot on used sites, even though it’s discontinued. That’s thanks to its durable configuration and design.

I found this 2016 Trek Domane 4.5 in my friend’s garage, so I decided to review this 2016 Trek Domane 4.5.

Coincidentally, I moved back home to rural Ohio some time ago, where the population is sparse and there are only large expanses of forest and rolling hills. I wanted to take the 2016 Trek Domane 4.5 to enjoy my hometown. And so, I began a ride of over two months.

I re-wiped this bike down and adjusted the slightly loose screws and seat post. The road in front of me would lead to a nearby nature park, and the first half of the road was a very smooth tarmac with only a few minor undulations.

I started in this 2016 Trek Domane 4.5 wondering if it would go on strike in the middle of the ride. However, it turned out that I was overly concerned.

The first thing is that the comfortable saddle and grip of the Trek Domane 4.5 made me feel relaxed as soon as it made contact with me. It was like I was holding a sponge, but with more support than a sponge.

Secondly, ISOspeed’s carbon frame and fork allow me to go uphill without too much strain, reducing the stress that the terrain puts on me. I can enjoy the upward climb with more focus.

Not only that, but the gentle geometry gave me more energy on the uphill. I didn’t feel any pressure on my spine from long rides.

In addition, it has a slack 71.9° head tube angle with a 73.3° seat tube angle. I think this is the main reason why I can always be able to maintain a comfortable position while riding.

Once again, the Bontrager R2 Hard-Case Lite’s tires provided me with reliable support. The tread pattern on it fits tightly to the ground as it rolls, firming it up and smoothing it forward at the same time. I was especially surprised by its grip when I encountered some of the steeper uphill grades, which had the feel of an old but still sharp knife.

I can say very directly that it will outperform some of the newer bikes like this.

Trek Domane 4.5 Downhill Review

If the uphill performance of the 2016 Trek Domane 4.5 is a 90 in my mind, the downhill performance will be slightly lower, but that’s only five points lower! But I think that’s a pretty good score for a bike that’s a few years old.

I still didn’t feel a lot of strain on my lower back on some of the drop-off descents. Yes, I dived slightly and the Trek Domane 4.5’s ISOspeed frame allowed me to gain acceleration more easily in the process.

And, I have to say that it is configured with a Shimano Ultegra 2×11 speed gear range which was exactly what I was expecting. The rich and dense gear ratios coupled with the stable crankset made my speed soar and the whole descent was very smooth and unobstructed. The big trees lined up on both sides were left as blurred shadows in my perspective, while the roadside grass could be vaguely seen swaying in the wind.

Its v-brake also kept up with me when I hit some of the more curvy turns, and I didn’t have to work too hard to hold the brake lever down and squeeze the corner with ease. However, the Trek Domane 4.5 may not have as quick a time to recover and is slightly less responsive than the hydraulic disc brakes. But in the uncrowded countryside, this had little effect on my riding.

Overall, it does have some limitations in terms of braking. But if it is on a wider route, there is no problem. So I would recommend not going to some muddy land to ride the 2016 Trek Domane 4.5, it is not suitable.

Main Features

Frame group.

First of all, its exquisite paintwork is on full display on this bike. The bike comes in very classic and understated colors, Matte Trek Black, Dnister Black, and Viper Red.

Secondly, carbon is already prevalent within the road bike segment. However, brands will still strive for excellence and keep looking for breakthroughs. Trek can be called a connoisseur in this area.

On the frame, the 2016 Trek Domane 4.5 features the exclusive IsoSpeed. as a result, it not only has the power transfer of a traditional carbon frame, but it is also smoother than a traditional carbon frame.

It maintains a diamond-shaped frame geometry that allows the seat tube to flex. This setup helps the rider in achieving an aerodynamically efficient position and reduces fatigue.

And, as it turns out, the Trek Domane 4.5 is not exaggerated. There are many past Spring Classic winners equipped with this frame.

The geometry of the 2016 Trek Domane 4.5 isn’t perfect, but it has the standards that an endurance road bike should have.

First, the 73.3° seat tube angle is not very steep; it allows the rider to bend gently to gain more efficient speed and stay smooth.

Secondly, the Trek Domane 4.5 has a 71.9° headtube angle. It gives a looser feel, but I think it’s just right. Because it doesn’t affect our flexibility when steering even when we keep driving at high speed.

On top of that, its 42cm rear lower fork length is relatively short. This also means that the rider will be riding closer to the rear tire of the bike, which helps to improve the rider’s speed up hills.

Components and Specifications

Shimano ultegra drivetrain.

The Shimano Ultegra drivetrain gives us a range of 2 x 11 speeds. This is more than enough play for a road bike.

Moreover, the Trek Domane 4.5 features a lightweight crank, hollow outer sprocket, and wider tooth spacing, which increases frame clearance. The lightened crank design optimizes the bike’s power transfer efficiency.

Not only that, but the 11-32T cassette will also be more advantageous when climbing, and the larger gears will make our pedaling relatively easier.

In addition, the front derailleur of Trek Domane 4.5 also offers a lighter shifting operation than before, mainly because of its new linkage structure. So, we don’t need to worry about not getting the exact speed we want when operating.

Shimano 105 Braking System

The bike is equipped with dual lever v-brakes that are not only affordable but also reliable.

The Trek Domane 4.5 has an integrated shift cable that is both lightweight and strong, yet very smooth and easy to use. Yes, you only need to hook your finger to brake. It’s rider friendly and easy to maintain daily.

In addition, the optical gel electric coating on its surface can protect the cable from corrosion. And the durability of the cable will be improved.

Bontrager R2 Hard-Case Lite Tires

The wheelset of the 2016 Trek Domane 4.5 features Bontrager R2 Hard-Case Lite tires on Bontrager Race rims.

First, the Bontrager R2 Hard-Case Lite tire is a road tire with Hard-Case Lite puncture protection for durability. Its lightweight tread casing increases the tire’s traction.

Therefore, even if we encounter a sharp turn, this set of tires will have excellent grip so that we can finish the turn smoothly.

Secondly, Bontrager Race rims are strong and fast, not only well-designed but also very light in terms of weight.

In addition, it is easy to disassemble. That is to say, we do not consume much energy either to maintain it or to replace it.

Other versions of Trek Domane 4.5

In the above article, we have learned that this bike uses mechanical brakes, while its other version is set up with a hydraulic disc brake system. They don’t bring the same riding experience. If you are interested, you can check out the 2016 Trek Domane 4.5 Disc Compact.

2016 Trek Domane 4.5 Disc Compact

In my opinion, the Trek Domane 4.5 with Shimano RS685 hydraulic discs is indeed slightly better in terms of braking.

And, it was also replaced with a disc-type balanced joint. It can make our handling smoother and make its braking smoother.

In addition, even in hot weather, its good heat dissipation performance can keep the bike running properly.

There is one thing to say, the hydraulic version of the 2016 Trek Domane 4.5 is a good choice if you have enough budget.

However, if you think you want a lighter road bike, then the 2016 Trek Domane 4.5 is the ideal choice for you.

What we like about it

• 400 Series OCLV carbon provides an ultra-lightweight frame
• IsoSpeed technology helps us reduce fatigue on the ride
• Concealed fender brackets prevent tires from being attacked by heavy mud
• Shimano Ultegra’s drivetrain is smooth and quiet enough
• Bontrager R2 Hard-Case Lite tires have great grip

What we don’t like about it

• Not strong enough braking system
• Fewer colors

2016 Trek Domane 4.5 Specs

Comparison T able

Trek domane 4.5 vs cannondale synapse carbon 4.

The Cannondale Synapse Carbon 4 is made of Synapse carbon, and it has a SynapseSense rear triangle. Hidden flex fields in the seat tube and seat post help absorb shock, while the proportionally responsive design allows the rider to get the most out of the riding position.

Compared with Trek Domane 4.5, its framework has its characteristics.

However, in terms of drivetrain, it goes for the Shimano Tiagra series, which offers 2 x 10-speed shifting. It is significantly weaker than the Trek Domane 4.5’s Shimano Ultegra drivetrain, both in terms of top speed and handling.

Obviously, at the same price point, Trek Domane 4.5 is much more cost-effective.

Trek Domane 4.5 vs Canyon Endurace WMN CF SL Disc 7.0

The Canyon Endurace WMN CF SL Disc 7.0 is a women’s road bike that comes in beautiful aquamarine colors.

At the same time, it has a saddle designed for women riders. This saddle has a decompression cutout to provide maximum comfort for female riders.

However, compared to the Trek Domane 4.5, it has a slightly more moderate set configuration performance. If you are a female rider who wants to try long-distance road riding, such a configuration is perfectly adequate and you can consider this bike.

2016 Trek Domane 4.5 vs 2019 Specialized Roubaix Sport

This 2019 Specialized Roubaix Sport frame is made of Fact 9r carbon. And its Future Shock provides a smooth feel to the rider by moving up and down like a telescopic mountain bike fork. In addition, the 11-34 cassette offers a wide range. And its geometry is designed to meet the rider’s requirements for an endurance bike.

But after our comparison, we don’t see much difference between them. But Trek Domane 4.5 is a bit cheaper.

2016 Trek Domane 4.5 vs 2019 Specialized Women’s Diverge Sport

The 2019 Specialized Women’s Diverge Sport is a women’s road bike.

In terms of components, it uses a Shimano 105 drivetrain and Shimano 105 R7070 flush-mount disc brakes.

And its tires utilize the 700 x 38cc Sawtooth Sport, which provides excellent grip for the rider. These are not much different from the Trek Domane 4.5.

However, it has a saddle built specifically for women and is ergonomically designed for women.

I think that everyone should choose the bike that is more helpful for their riding, and everyone is different.In case, the above comments are helpful to you, please remember to share the subscription. Have a great day!

Smooth ride

Saddle White bar tape Heavy wheels

The ride is very smooth through the saddle, but a lot is transmitted through the handlebars. The bike is very stable on downhills up to my max of 44 mph. Upgraded the cassette and chain to Ultegra and shifting the rear became much smoother; cheapest maintenance change to do when your chain is worn. Upgraded the wheels to Dura Ace and lost about 1.25#; climbing instantly became better. Next upgrade is carbon handlebars 46cm and hopefully I'll get less road transmission into my arms. The dirty white bar tape will go away. The saddle was replaced early on with a Brooks. I average about 200 miles per week and do a significant amount of moderate climbing. So far there is about 7000 miles on the bike and I really enjoy it. I didn't give it a 5 overall because there is always something better out there, but this is the bike I'll be riding for a few more years at least. One of my better purchases. I recommend this for anyone looking for nimble, comfortable ride. Probably not for a racer, because lighter models are available.

No longer care if there is chip seal. Smooth ride for your butt. Good component set.

Race light wheel spokes do not hold up. Remember you are isolated from a lot of the impacts the bike is absorbing. Hands and feet still vibrate. Section of road with caterpillar track damage hurts my feet but the vibrations don't get to my seat. White bar tape immediately looks dirty. Bontrager seat is not comfortable. 4 series carbon not so light. Notice seat movement with cadence over 105. (but smoothed out stroke, originally noticed movement over 90 cadence). Carbon bike: SKS raceblade fender mounts mar the surface finish. I need to get the Trek fender mount accessory pieces.

Smoooooth! Good commuter and distance ride. Bet you will change out wheels and seat. Reliable and takes a beating so you don't.

Very stiff, very smooth, great handling. 6800 ultegra group is brilliant. Wheels feel excellent, stiff durable and smooth. Spokes are standard dt which will make replacements cheap and easy to source.

Seat hurt me, but others may like it...not a deal breaker.

2014 Trek Domane - I've been riding and racing for about 15 years, have owned 1 custom steel, 2 aluminum, 1 carbon and a scandium alloy bikes. This is a huge step up! The marketing jargon is true, the bottom bracket is as stiff as any bike I've ridden. However the isospeed REALLY works, I was even pedalling seated across stock grids! It handles great, and all (except stock saddle) the bits feel spot on. Oh and it looks great. It's actually a really nice pearlecent white which you can't see on the website. I test rode giant defy advanced, cannondale synapse, specialized roubaix. All the others were good, but this was the best, I don't want to change anything other than the seat. This was also the cheapest. Oh yeah I'm not little either with a fighting weight of 90 kg if it can be this good for me, I reckon it's pretty darn good. Highly recommend it.

Those little nuts on the presta stems Reflectors Air in tires

This is a great bike. I like riding it.

Ultegra/105 components, superior seat vibration relief, light and stiff frame, metallic paint scheme.

None so far after 500 miles

Great mix of Ultegra and 105 components for this price range. The standout though is the Iso Speed decoupling, its no gimmick and definitely smooths out road chatter and bumps from uneven pavement. Its not a miracle cure and your hands still get rattled up on rough pavement but coming from a Synapse using the same saddle, there is a HUGE difference in what you feel transmit to your seat. The frame is beefy and offers great comfort for up to 63 miles, my longest since owning it, with just slight discomfort which I know my upcoming fitting will remedy. The frame has a BB90 bottom bracket, hidden fender bolts, a chain dropping prevention device (I've dropped mine 3 times, LBS says it needs adjusting) and will take 28mm tires which is my next upgrade and has been highly recommended. The other Bontrager RL components seem like good pieces so far.

Trek domane 3rd party reviews, 2022 trek domane review - a tpc quick-take.

• IsoSpeed Technology: A standout feature, the rear IsoSpeed decouplers absorb fatiguing road chatter. They make the ride unmistakably smooth, like riding on a cushion of air.
• Storage integration: The built-in storage compartment on the down tube is genuinely useful. It beats having to strap a saddlebag to the frame and clutter the bike.
• Versatility: Generous tire clearance (up to 38mm without fenders) and the overall design mean the Domane is adept at handling both tarmac and light gravel. It opens up avenues for exploration beyond the usual road routes.
• Endurance geometry: Maintaining the spirit of the Domane lineage, the 2023 version offers a comfortable, upright riding position suited for long rides.
• Weight: (18.5 lbs size 56cm) The Domane, with all its tech and features, is on the heavier side, especially in its base models. This might not be a concern for the casual rider, but weight weenies might raise an eyebrow.
• Cost: The technology packed into the Domane makes it a bit pricey. While you get a lot for your money, it might be overkill for those not intending to utilize all its features.
• Aero compromises: Compared to race or aero road bikes, the Domane doesn't cut through the wind as efficiently. It's built for comfort over speed, and it shows.
• Over-engineering for some: While tech enthusiasts might rejoice, the myriad of features could be overwhelming for someone looking for a simple endurance experience.
