At just over 200 pounds our wheels will definitely last. We do have the 24/28 spoke count option which will increase the weight limit to right around 230 pounds for the 38mm tubulars. Above that and you really should be looking at a higher spoke count and for every day wheels an alloy set.
I believe we have emailed, but I did want to clear this up in case other people around the listed weight limit for the 20/24 option happened to be looking.
