Lighter Than Anything Else on Gravel
The World's Lightest Gravel Wheels‡
“Sparrow’s light weight is very noticeable, whether accelerating for a KOM unloaded or settling into an hours-long climb on a bikepacking trip.” — Bike Gear Database
Gold Medal Winning Spokes
With two Olympic Gold Medals, two Olympic Bronze Medals, and over 50 XC World Cup podiums in the last 2 seasons, Berd spokes are the winningest XC MTB spokes in the world. Lightweight, strong, vibration damping. "If you're not riding Berd spokes for mountain biking, you're at a disadvantage."†

So light, fast, smooth on gravel. Love these.
Rob is great to work with and to answer your questions.
After a few weeks of use, I can tell wheels spin up faster/easier and have lower resistance to keep rolling faster/longer with onyx vesper hubs.
Wheels seem to hit a wind resistance wall at higher speeds 17-21mph. Need to install a hub speed sensor because it shouldn't be attached to spokes.
I don't notice wheels cushioning at all because I'm running higher/safer pressures to protect carbon rims. I damaged aluminum rims several times before mounting Berd. It's better to learn on cheap wheels before putting something nice on like Berd.
Painting spokes seems to protect them from fraying and may make them more aero. Looks great.
I'm still evaluating to see if I want to mess with a set of Berd with rim brakes. Truing seems to be much more involved with removing tire and I may not want to mess with on aluminum rim brakes.
Thank you, Rob!
Wow, these wheels roll so great, and are super light.
I built them up for my wife to use on her gravel bike.
Per actual weight they saved 757gm (1.7lb) over my prior DT Swiss aluminum wheels. That's huge and very noticeable when riding. I'm running 45mm tires at 26/28 psi f/r so the ride is already smooth and muted, but these wheels still take off some of the remaining harshness and dull sharp edges. The ride is more quiet too. High speeds and cornering on pavement are all fine. Outside of the more muted ride, there's no sense of any elasticity in the spokes. When I got them, I checked and they were nicely true with even spoke tension and centered dish. I'm very happy with them.
These are amazing!
