Funny story: I change bikes every 3 or 4 years so I was "forced" to upgrade to the Fx Sport 6 because my current bike is a dark grey trek so the 6 was the only one that would allow me to upgrade without having to answer the questions from my wife "is that a new bike?" Awesome bike btw

I ended up getting the Fx Sport 4 in Dark Aquatic. Beautiful bike and is by far the best bike I have had coming from target “higher end” hybrid bikes. Bike is light, easily 4 LBS lighter than my Schwinn Hybrid Elite bike, easy to carry. It is fast and Agile while keeping me nice and upright and comfortable. This bike should last me a long time can can only imagine what the 6 series is like. Hope this is helpful!

I purchased the FX Sport 6 a few weeks ago and it’s awesome! Strong carbon fiber frame, carbon seat post, and wheel set. Purchasing the carbon handlebars soon. This bike is fast, baby! Keep riding!

Excellent comparison, I’m very interested in the FX6 Sport, I’ve always wanted a flat bar road/gravel bike & this bike is exactly what I’m looking for. I had a Domane SL6 but just couldn’t get comfortable on it for some strange reason. I’m a mtn biker, Stache 9 & 2021 Top Fuel 9.8, the flat bar look & feel is what I want to try for gravel, nice job, new sub here from Philadelphia!

I love this review and it came in very handy when it was time to choose which bike was right for me. I have planned all along to upgrade to tubeless. It made choosing the Sport 6 very easy. I've had it for about a month now. The tubeless upgrade was easy and I love putting the miles on! Great bike for someone transitioning from single track Cross country to gravel riding.

*Looked at a lot of options for getting my **Latest.Bike** . Great find in SAVA. Super light, nice components, really good value as it comes with many options only found in much higher priced bikes.*

Thank you for this awesome review. Just today I bought the FX sport 5. I did not see the point of spending an extra $1000 CAN. Dollars for the carbon wheels and a 2.0 lb. Lighter bike. I also chose the red carbon color. I was glad to hear at the end of your video that you prefer the FX sport 5.

What a great quality explanations. Thanks for your work on this!

Great review ! Very informative. This weekend I went out to look for a new bike to replace my aging Fuji hybrid bike. I want something much lighter than my 33 lbs Fuji, so I can go faster and go after some road hills like a road bike with less effort. I much refer the flat bar and not the drop bar. I looked at Cannandale, Specialized, and Trek. Between the great information and advises I received at the stores, my internet research, and this review from Talalipop, I placed the order for a FX Sport 6 version. Scheduled for late June arrival. Yes, high end FX S5 and S6 are not available around my area, supply chain issue hit all bike brands. Putin war criminal probably makes the situation worse. Slava Ukraine ! Oops, sorry, I digress.... Well, from a pure bang-for-your-buck point of view, IMHO, S6 is a better purchase than S5 or S4. The key reason: Bontrager Aeolus Elite 35, OCLV Carbon wheels which are part of only S6 model. These wheels are $1k if you purchase them separately. If you start with the S4 price and upgrade with these carbon wheels, you are already at that S6 price, not to mention all S6 upgrade parts. Similarly, if you start with the S5 price (parts are quite similar to S6) and upgrade with these carbon wheels, then you are over the S6 price tag. Note that all Carbon part of FX Sport are life time warrantee ! and 2 years warrantee of free repair or replacement if the wheels are damage even if your car accidentally ran over them. I have never spent this much money on a bike until now, but after 18 years of fitness biking, this is a great investment for my health. Looking forward to riding it, and adding many more years of fitness exercise. Good luck with your purchase. And thanks Talalipop !

I really didn't think 1x system will work for gravel/fitness bikes but have using the 40T 12-46 for few months, it really works for both speed and hill climbing and truly a "do it all" setup for all purpose bike.

Really like your comparison I too agree with you as the fx sport 5 smoke red is the eye catcher for me too. Glad that I bought it from Trek Sacremanto last month

I will keep saying it again and again. Trek should definitely promote you and recognise you far more. The impact you are having is simply incredible… I am very angry with the silly U.K. prices. I also wish they did a sport 5 with just the fork in carbon and all the rest of the equipment…price will drop below the 4 or roughly same..

Good job on your videos. I have watched quite a few before buying 3 x Trek bikes for our family last week. Keep up the good work.

This is the ultimate comparison video I was looking for, thank you.

Great video, thank you. I should receive my FX5 Sport in red next week, Can't wait!

thanks for reviewing these bikes. thank you for mentioning the number of teeth on the front chainring. I don't know why so many bike channels ignore this variable. i like the geom, but not the color options. dark colors for bikes, not a fan.

Trust me - when you see the 6 - when you pick up the 6 - you’ll want the 6. I sold my stigmata to get this . Flat bar gravel has always made more sense ; credit Trek for listening.

Nice and comprehensive review. With that said, I just bought one of the very last remaining new 2021 FX Sport 4's left in the entire US. My FX will never leave pavement so I much prefer the narrower rims and 32C tires. Also the 2021 is a bit stretched out more and I am a tad more bent over then the 2022 model. The ISO speed decoupler smooths the ride somewhat and the GRX drivetrain is better then whats on the 2022 model equivalent. For its intended purpose the 2021 model is hands down the way to go. Its almost like my Madone but with a flat bar. In fact, the 2021 FX Sport Carbon 4 model frame is the same as earlier series Domane frames. I cannot understand the "gravel" concept. I have different bikes for different purposes. If I ever want to go the " gravel" route , I will ride my Fuel EX 8. Or the Verve 3. BTW one of the best things of the 2021 FX 4 Sport Carbon was the price. I drove almost 200 miles to get it but it was slightly over $700.00 off the original price. Sweet indeed.

My red FX Sport 5 2022 comes in this week! So excited! Upgrading from a Dual Sport 3.

Excellent review The FX Sport 5 has just been announced for Australia, Aug 2022, however over 12 month wait, ETA Sep 2023...will go to my LBD and lay down a deposit tomorrow, the only real difference I can see between FX Sport 5 and 6 2022 model is aluminium v carbon rims, and tyre differences. (English Spelling) I am a heavy rider so will ride on the metal rims. thanks for the review and pointing out the difference in geometry between 2021 and 2022 models..

You make us updated about trek Line up... Thank you Man🏅 9:48 Suggestion - You can give link pop up in your video for seeing that video 👐

Great video! Thanks. Greetings from Poland

Great comparison! I keep toying around with the idea of upgrading my 10-year old Trek 7100. Looking at the FX Sport 5 but with added Redshift suspension (PA roads are horrid after all!).

Great review. Just got and rode my 6 first time. Nice bike.

Very good review!!!

2022 version is super sleek looking. Love it. I might have to get the new version of this. Wonder what is new for 2023?

My 2022 Trek Fx Sport 6 is arriving within 2 weeks. Can't wait! Been waiting since April 2021. My original order was the 2021 model, but that model is no longer available. The LBS here is honoring my deposit for the 2021 model, so in effect, I will be paying for the price of 2021 model but am getting the 2022 model! Sounds good to be true? We'll see if the Store Manager will fulfill his promise. Will update this comment once I get the bike.

These are nice looking bikes. They remind me of the Specialized Sirrus X and my early 90s Cannondale M700 mountain bike that I still ride today.

Awesome review. Thanks for sharing!

These look great I currently have a basic DOMANE, hybrid looks great too 😍😍

Great review !! Thank you 🙏

between this and trek checkpoint, which is a gravel bike, I think Checkpoint give more bang for the buck.

Thanks, vid made a big difference,,,, 2600euro for the 5 here in Ireland, when it comes

Another great review. Given the $300 difference between the 4 and the 5, and, as you pointed out and I confirmed: Trek is actually putting the Promax brakes on the 5 right now, might the 4 be a better buy with 300 to spend on upgrades?

The trek site has the set of wheels that come with the 5 weighing at 560g each front or rear. Total weight would be 1120g for the pair. The 6 wheels on the same site weigh 745g front and 940g rear with a combined weight of 1685g. So explain how the wheels that come with the 6 are lighter and how the bike weighs less when everything else is the exact same. Even with the hubs included in the weight of the 5’s wheels it’s still less than what seems to be an additional 400g which puts the wheels still at a lesser weight on the Trek fx sport 5. Now I know this must be wrong because I own a 6 and it’s lighter than a 5 but it seems like the wheels at least on Treks site are not.

Broooooo❤️❤️❤️❤️❤️❤️❤️❤️❤️ love the video so so beautiful explain very helpful for all. Love it Thankyou 🙏🏻🙂🙌

I've been riding a road bike but rarely ride with my hands down on the bottoms of the handle bars, I usually ride with my hands around the top edges..so why have drop bars if I'm not using them? I test rode an FX4 but it was a Med frame, we determined I need a Large..which would kinda improve my position and how it feels. I'm going back there tomorrow as they have assembled an FX3 and a FX 2 in Large. But now I'm pretty sure I want a Sport 4, 5 or 6, not just because of the lighter weight, but I'm really bothered by the rough pavement on the streets, they say carbon feels smoother than aluminum. Between the 4 and the 5 there is only about $300 difference so like he says at the end of this video the 5 seems to be the best choice (I like the dark blue better btw). But I been reading lots of comments here and at a bike forum, and those which bought the FX 6 all rave about how happy they are with them, "they are fast and fun, etc".

Excellent comparison!

Thanks! It's very helpful video!

Awesome video ! Fx 6 sport Carbon w carbon wheels is way to go. Just ordered

@Talalipop MTB. Nice video! I bought a 2023 FX3 last week ($1049) but decided I should have gotten the FX4 Sport instead to have the full carbon frame. Went back to the Trek Dealer but didn't really like the colors and that it had the same Deore components as the FX3 I was exchanging so I ordered a 2023 FX5 in Red Carbon Smoke for $2099. Do you think the 2023 Trek FX Sport 5 will be worth double the cost of the 2023 FX3 I had a week? I’m mostly a runner but plan on biking once a week between 15 to 50 miles. Thank you kind sir

Very good explaining sr thanks you very much

Ordered a FX6, ships in March '23, might be next year's model

Great Videos! Thinking about the FX Sport 5. Can the FX Sport 4/5/6 accept an internal dropper post?

After endlessly researching bikes and getting ready to buy...and then endlessly searching for a Cannondale Quick Cx1 or a Specialized Diverge E5 Comp EVO, which don't exist for sale in this world...i stumbled upon the Trek FX4 Sport Carbon Lithium Gray. I thought it was a pretty good comparable bike to what i was looking at, plus the store had 1 left in stock so that is what i ended up with. I have had for it week now. Def don't have any complaints but i don't have any experience to compare to other bikes. I did read that the FX4 is using less quality parts then the year prior which is disappointing to learn.

why did the sport 4 get heavier in 2022? The 2021 model was less than 22lbs and this one is almost 24. I'm guessing the wheels?

Compare with Checkpoint? Other than drop bars

I plan to purchase the FX Sport 4 model and your video helped solidify my decision. My only uncertainty is the color - Trek White or Lithium Grey? The stores near me do not have any in stock. Do you have a recommendation based on your experience?

Has anyone had any issues with the cables going through the headset making a "grinding" noise? I have.

What is the weight of the bikes?

Thank you for the video. Nice comparison! At the beginning of the video, you briefly show the FX Sport 5 in Red Carbon Smoke with another FX Sport (I assume) in blue leaning against the wall. However, it is clear the geometry of that bike is not the same as the current FX Sport models you are reviewing. The geometry is slightly different and is most noticable with comparing the size of the head tube? Which model is the bike leaning against the wall?

great video

Any chance Trek would sell just the frame and fork on any of these models and then I could make my own set up?

Overall Lesser components for a higher price. Btw the posted price for each bike in this video has increased $100- $200

Hi Talalipop ! I want to ask if the fx sport 5 car has size XS or not? Why the new version 2022 doesn't have iso speed ? Is the new frame better than the old fx sport 4? I noticed that the options of the old version fx carbon 4 2021 are the options of the new version fx sport 5 2022. The only difference is the new frame and no iso speed and the price increases by about $200. I just want to know if this new frame technology is better to replace iso speed or not? Thanks

why fx sport 5 is unavailable in the trek online stores ,im planning to purchase

Why would Trek want to make the FX carbons a gravel bike because isn't the dual-sport a gravel bike? Thanks :)

Thank you for the video . I just purchased the 2022 Fx4 Sport. Coming from a hard tail MTB. This bike is smooth and fast. Do you think it’s worth to upgrading to a FX Sport 6 for another 1k?

Great video! Forgive my ignorance but since you work for Trek I have a few questions. I don't need the 4, 5, or 6 for gravel, I'm only interested in road. I see that they come with 40 tires. 2 questions: 1. Can you get thinner tires without changing the wheels and 2. Can you get smooth road tires instead of the more knobby ones?

So the upgrade between the 5 & 6 is the carbon wheel set?

Thanks for the detailed explanation. Is it still possible to mount a rear rack for panniers on the FX Sport 4/5/6?

I know they changed the geometry but will you still be leaning forward somewhat when riding it? Not like sitting at a 90 degree angle or anything right?

Thank you for this great video. Is the FX Sport 5 using the Shimano Break system or Promax? Someone told me it was Promax so I was a bit confused.

If you had to pick one.. Xcaliber 9, Roscoe 8 or Procaliber 9.5, which would you choose?

When is trek marlin series 2023 release?

Can you please tell me what's the difference between treks alpha platinum, gold and silver aluminum. I have searched all over the internet but couldn't find a fitting answer?

I live in a 3 story walk up in nyc, should I get the 6 for weight savings or save the money and find some carbon wheels on eBay or something later on. I only commute, just getting tired of my current 29lb bike and also had enough of the single speeds of had over the years, ny isn’t as flat as some ppl think. Lol

fx 4 sport Shimano Deore M5100, 11-51, 11-rzędowa

The 2023 models are out now. Is exactly the same?

isospeed is good?

Talalipop, great video explaining the differences. One question to ask as I just got off the phone with Trek Support a few minutes ago. If you were to have an FX4 Carbon go head to head with an FX6 Carbon for overall speed, which bike would have a higher top end speed, provided the riders are of equal weight and cycling ability? It almost sounds as of the 4 is faster but the 6 may be faster overall, because it's lighter? Can you provide a factual answer on this?

I am still not sure about a 1x drive train. Other than simplicity and weight what reason do I have to change from a 2x?

I think also no'5

Tried a 2022 FX 4 a few days back and found it had a very clean look, decent kit, and an extremely smooth ride - even across a grassed park during my limited test. But I found the bike's prominently upright riding position off putting coming from my 10 year old, Can 0 Ale Quick CX1. In retrospect during that 30 minute ride I felt no pain, even forever my messed up right palm/wrist. Hey, maybe it is time for a switch up? I wonder about riding this for a 25 mile ride - any experiences?

Great 👍🏽

FX Sport 4 (2022) basically is the carbon fibre version of the FX 3 (2022), all the same except the frame

Are these drop bar compatible

I am 6’2, should i get a l or xl?

Hey just curious how tall you are ? I see you on the small but you look TALL (lol) I am 5 ft tall not sure if I am XS or a S on the FX 4

do you think , the fx sport bikes make sense, for someone only doing pavement riding ?

Put Canadian prices💰

2022モデルの４か５を買いたいんですけど店頭在庫がナイんですよね… なので２に乗ってます(´･ω･`; )

none of these are good bikes because of the gearing and single front. better off buying an fx2

Fx sports 5, 2022 model is a horrible bike in every way. How could Trek produce this piece of crap...having created such a great bike in the previous FX sports 5 model. Why is everyone trying to make us believe we are privileged to have a smaller range of gears? The sitting position is just too upright to generate speed. I went back to my BMC Alpine today, a 700 dollar bike, and it beats this new trek hands down. I'm talking road riding but I'm sure this new model can't suddenly transform itself from it's slothful self when it's running on gravel.
