Customer Reviews
Great wheels -
Shopping for Berd spoke gravel wheels now
Super pleased with my wheelset, paired with Pirelli Scorpions the bike flies, most noticeable on the hills, feel well planted, not found anything to fault them on.
So I inquired about the new Berd gold wheels. The customer service is simply the best! I just finished the whiskey off road race in Prescott and set an insane amount of personal records with this wheel set! Very happy with these wheels!
Only a couple rides on these, but they are more than noticably faster and lighter than any other wheelset I've ridden, by a lot. I haven't ridden on anything beyond mild xc singletrack. Hopeful that they are not too flexy when I need to push them harder in high speed corners, while being a bigger rider (215lbs).
I've had several high-end carbon wheel sets and none of them even come close to the Hawk30 Golds. Light, strong, stiff where you want them and so compliant through the corners and over chunk. Feels like I'm floating over the rocks and roots and absolutely soaring up climbs. You can push so hard into corners and berms and spring out of them without ever missing a beat. Can't recommend these enough!
