NOTE: Because we handbuild all our wheels, we can make most of our wheels in a stronger version for large riders. If you weigh over 190 lbs, we should talk about your intended use and riding style before you pull the trigger on a new set of wheels. We can probably make a wheel for you, but it may not be a stock version. You can email for more information or to start a conversation.

Email them. I bought a Hed Stinger 90 front wheel a few months ago and had a few questions, they will reply promptly.
