When DT Swiss decide to do something there's no messing around, they do it properly. Don't believe us? Check out the new GRC 1400 gravel wheels. 

The rims are 24mm wide internally, making them perfect for large volume tyres, and the 42mm depth has been optimsed to give you the best aero advantage with 35mm tyres. Think aerodynamics doesn't matter when you're racing off-road? Think again. As soon as you're past about 10mph, aerodynamics are the main thing holding you back so any improvement will help you ride faster. They roll really well, too. Tested with a 35mm tyre against the CRC 1400 cyclocross wheels, the GRCs came out with a 5% reduction in rolling resistance with the tyres at 3.5 bar, and a 7% reduction at 4.5 bar. Told you they designed these to be fast...

They're also tubeless-ready (naturally) and have 130kg max system weight, so they're built to take pretty much whatever you can throw at them. At the centre, you get DT Swiss's tried and tested 240 SPLINE hubs with the 36t ratchet system and a convertable freehub body that you can change from Shimano to make them compatible with SRAM's XDR. Spokes are DT's aerolite and aero comp and are laced in a 24x2 cross lacing pattern and, of course, they use internal nipples - they are aerodynamic after all. 

One other big change is rim diameter. Since load of gravel bikes use 650b wheels instead of 700c, DT are offering all their new gravel wheels in both sizes so no matter what frame you choose they have the perfect wheels to match.
