Revamped Felt Fx carbon cyclocross bikes unveiled at Sea Otter Classic

Lighter, comfier and faster with disc brakes, thru-axles and more tyre clearance

It’s not even May yet but this year’s ’cross season is already heating up.At this year’s Sea Otter Classic, Felt Bicycles unveiled a freshly overhauled Fx range of carbon cyclocross bikes with lower weights, smoother ride qualities, better pedalling efficiency, and more tyre clearance – not to mention a full complement of modern features such as disc brakes across the board and thru-axles on most models. 


2016 Felt Fx key features:

  • 950g/850g claimed frame weight (55cm, Fx/FRDx)
  • 400g claimed fork weight
  • Front and rear disc brakes, post mount, 140-160mm rotors
  • 100x15mm front and 142x12mm rear thru-axles
  • 1 1/8-to-1 1/2in tapered head tube
  • BB386EVO press-fit bottom bracket shell
  • Convertible internal cable routing with pathways for dropper seatpost
  • Clearance for 36mm-wide tyres

Felt’s improvements to the carbon Fx cyclocross range are pretty much what you’d expect, but even then, the claimed figures are quite impressive. According to Felt, the standard 55cm Fx carbon chassis comes in at just 950g while the flagship FRDx is just 850g – decreases of 100g and 150g, respectively, and well within spitting distance of the lightest road frames on the market today.

Felt says the bridgeless seatstays help soften the rear end for a smoother ride on bumpy courses:

With a claimed frame weight of just 850g for the top-end FRDx model, Felt seems to have taken the lightweight ’cross chassis crown

In addition, bottom bracket stiffness is supposedly up a substantial 21 percent for the standard Fx while front triangle torsional stiffness jumps 11 percent over what was already a very rigid chassis. Nevertheless, Felt says the new bikes are slightly more comfortable, too.

Many of felt’s new fx ‘cross bikes will be set up with 1x drivetrains as standard equipment. the f1x model even comes with both round and elliptical chainrings from rotor, leaving the final choice up to the buyer:

Felt is once again equipping all of its carbon ’cross bikes with tapered 1 1/8-to-1 1/2in head tubes but their usual BB30 bottom bracket shells have now been replaced with wider BB386EVO ones. The chainstays can be pushed further apart as a result, and all of the new Fx frames will now take tyres up to 36mm wide while still retaining a quick geometry suitable for racing.

The rear disc brake caliper is mounted to the chainstay, allowing the seatstay to be thinner and lighter for a smoother ride. dt swiss thru-axles are used front and rear:

Thru-axles and disc brakes are featured across the board for carbon models. For now, Felt is sticking with currently standard post mounts and a 15mm front thru-axle

Alloy ’cross bikes get overhauled, too, with wider BB386EVO bottom bracket shells, partially internal cable routing layouts, and new carbon forks. All of the aluminium frames carry on with quick-release rear dropouts, however, but the F55x at least gets a thru-axle up front.

All of Felt’s new ’cross bikes are slated to arrive in shops no later than August.
