Trek DS vs FX – A thorough comparison

What if I told you that there was a bike available that could traverse many terrains and would allow you to make adjustments to it as you see fit? Well, you’re in luck because the Trek DS and FX models are two of such awesome bikes. 

I’m a firm believer in green-living since a few years ago when I understood the detrimental effects of pollution on the animals and plant life on our planet.

Sometime in May of the year 2016, I ditched my car and opted for the environmentally friendly alternative of bike riding. Now, I ride my bike everywhere and all year round, as much as the weather permits me to.

So, believe me when I say that I understand the limitations that come with life on a two-wheeler. With technology and innovation, this doesn’t always have to be the case.

I have here two awesome bike choices for you who are considering daily bike rides for the environment’s sake or for any other reason you might have.

Trek DS vs FX – How do they compare?

Frame and Fork 

An SR Suntour NEX superior fork is featured on the Dual Sport trek bike and the FX Carbon is what you will get on the FX bike.

Both bikes offer users a lightweight Alpha Gold aluminum frame which is both lightweight and sophisticated sleek.

This lockout feature provides efficient riding where you can close it on smooth pavement and open it on rugged terrain.

This carbon fork works effectively to provide the right amount of cushioning from road vibrations and the grippy handlebars make it perfect for control regardless of the terrain.


Trek DS has the Bontrager XR Endurance Elite lock-on which is better than Trek FX which features the Satellite IsoZone Plus.  

Both bike’s stem feature Bontrager Elite 31.8mm clamp, Blendr compatible for accessory integration, 90mm length on the DS, and 100mm on the FX. 

This is the cool function that I think everyone should have the pleasure to try out because, with the compatible system, you can add on fenders and rack mounts to help you carry any baggage you may have.

Seatpost is both represented by the Bontrager alloy 27.2mm, 12mm offset, 330mm length and because both grips have been ergonomically designed with grippy arms, it should be easy to keep maintenance.


The chain is for both KMC9 and the Shimano brake vary by just a whisker with the MT2000 fitting the Trek DS and the MT2100 flat-mounted perfect in the FX model. 

The Front derailleur for both FX and DS bike models is the Shimano Acera T3000 34.9mm with a clamp, top swing, and dual pull. 

The rear derailleur differs for the two where the Trek DS is fitted with Shimano Alivio T4000 and the FX spots the same Acrea T3000.

Cranksets are for both bikes, the Shimano MT210 46/30 chainguard 170mm for DS and 175mm for FX, and the shifters are Shimano Acera M3000 in 9 speed.


Rims on both Trek models are Bontrager Tubeless Ready Disc, 32-hole with Presta valve, and feature stainless steel black with the 14 grams spokes. 

Bontrager GR1 Expert, hard-Case Lite, wire bead 60 TPI 700x40c are the type of tires you can expect on the Trek DS while the Bontrager H2 Hard-Case Lite, wire bead 30tpi 700x32c are spotted on the Trek FX.

Racks and mudguards are part of these bikes’ structures further adding to their convenience of use. A special feature that comes in the form of the DuoTrap S fitness app integrates a Bluetooth sensor into the frame and allows for connectivity with your smartphone that also allows you to send ride data to your phone.

These bikes also feature extras such as the Blendr Stem technology that allows you to install bike riding accessories such as lights, GoPro, or Satnav, plus a water bottle holder.
