The Strongest, Most Durable, Most Extreme Wheels Berd Has Ever Designed
Berd HAWK30X Carbon Downhill, Enduro, and eMTB Wheels
Made specifically for downhill, enduro, and eMTB. These are not just a marginally improved version of the HAWK30, they are in an entirely different class.
Gold Medal Winning Spokes
The HAWK30X wheels feature our brand new PolyLightX spokes, exclusively available with the HAWK30X. With a diameter that is 50% larger than our gold medal winning PolyLight spokes, PolyLightX spokes are 44% stiffer and have more than double the abrasion resistance — yet they weigh only 3.5 grams each, just 1 gram more than our standard spokes. Built on the same platform that earned two Olympic Gold Medals and over 50 XC World Cup podiums, then engineered even further for the most demanding riding on the planet.†

Customer Reviews
Nice detailing, fantastic construction & featherlight. Awesome addition to my newly built Ibis Ripmo V3 👍👍👍
I've ridden well over 20 high end carbon wheels over the years and I have the say I'm incredibly impressed with the Hawk30X wheels. I have about 500 miles on them now. No truing, no damage. I'm 200 lbs and am riding hard. The combination of compliance and snap is unrivaled. Just do yourself a favor and get a set.
† Based on both the highest number of Olympic gold medals and the highest percentage of UCI World Cup cross country wins achieved by any spoke brand during the 2024 and 2025 seasons.
Berd stands for Bike + Nerd, because that's exactly who we are. We use real engineering, real testing, and real data to build the best bicycle wheels in the world. BE A BIKE NERD.
