The FX series is the best-selling line in Trek’s history, blending the separate worlds of hybrids, road bikes, and arguably gravel bikes. Featuring a rigid fork, 700c wheels, and semi-upright position, the FX is aimed at gym or fitness enthusiasts who want to add cycling to their routine with a bike that’s faster than a beach cruiser, but without fully committing to drop bars or higher-priced bikes.

Both the FX 1 Disc and FX 2 Disc have full redesigned Alpha Aluminum frames with internal cable routing, and the flat mount standard for attaching the brake calipers. They also have ThruSkew, Trek’s proprietary wheel alignment/attachment system.

Why? What would you replace it with?
Seems awesome to have integrated speed and cadence sensor – removing the need for 1 or 2 other sensors strapped to your bike with zip ties.

I have duotrap on my Emonda, it works great! Wouldn’t want to get rid of it.

After personally dealing with ThruSkew, I can confidently say it’s a sorry substitute for thru axles. It’s a cost saving measure in the face of greater consumer demands and stiff tariffs. Also, because loose ball QR hubs are the cheapest option. No shop worth its salt carries the FX 1. It sucks, and shops make peanuts on them.

No one at the entry level cares about internal cable routing, much less knows what it is. It’s hilarious to see shiny pictures of a bike with a THREADED FREEWHEEL.

Trek where the K is for Kwality!

At least they aren’t doing threaded headsets on these from what I can tell. Modern manufactured bikes with low quality modern made outdated components just don’t make sense. Threadless stems, sealed bearings and cassette hubs work really well why go backwards?

Seems strange to still see 3x cranksets on new bikes. Think these will ever go 1x en masse?

Cannondale got it right on the new Treadwell with 1 x across the board. The “sweet spot” middle version gets the new microshift Advent 1×9 drivetrain with wide range (11-42T) cassette…..for $750.

I love these bikes, I got a FX2 back in maybe 2009? Anyways, it’s worked flawlessly for the last ten years. Only problem I see, is that my ten year old model still looks the same as the new ones. There’s zero reason to upgrade.

Yes. I have a 2020 FX Sport 4 and I have the Duo Trap system and it works great. I’m very happy with it.
