FeltNexar UD Carbon STD
The lower-priced version of Felt's Nexar aero road bike. The frame and fork use Felt's standard UD Carbon STD layup instead of the FRD 12K Carbon Light of the FRD and Pro models, while the shape, the one-piece carbon cockpit, the zero-offset seatpost and the geometry stay the same. Felt sells it only as the complete Expert (Ultegra Di2) and Race (105 Di2) bikes, without a power meter and on Vision SC45 wheels.

Our verdict
Overall
out of 100, average of 7 categories
The Nexar's shape, one-piece cockpit and relaxed race fit for a lot less money, with sensible Ultegra Di2 or 105 Di2 builds on 28 mm tyres. The saving shows on the scales: around a kilo heavier than the FRD build, with no power meter and Vision's entry-level SC45 wheels instead of the Metron.

Fit
The Expert and Race product pages show the same Nexar geometry chart and cockpit sizing as the FRD models: 90 mm stem with 360/400 mm bar on the two smallest sizes, 100 mm with 380/420 mm on the middle three and 110 mm with 400/440 mm on the two largest.
SourceVersions
Felt uses two layups on one Nexar geometry: FRD 12K Carbon Light for the FRD and Pro builds and the framekit, and the standard UD layup, which Felt calls its benchmark and describes as more durable, for the Expert and Race builds. In size M Felt lists 7.6 kg for the Expert and 7.963 kg for the Race, against 6.48 kg for the FRD Dura-Ace build.
