I have 4 Rhynolite wheels that were picked up last year for cheap from Performance Bike before they went out of business. The are light like a rhinoceros is light, but plenty strong. Paid between $10 and $20 for each wheel, with the original price around $80 each. No concerns about the ability to carry a load. I don’t travel especially light and do plenty of off-road riding with them with no signs of any problems.
