Usually found on Harleys, solid wheels are a rare sight on bikes meant to go fast. Strawber makes carbon hubs and rims for spoked supermoto wheels. By replacing the metal spokes with solid planes of carbon, the company hopes not only to reduce the overall weight, but also increase strength. Reducing unsprung weight is one of the most effective ways to boost your bike’s performance. Weighing just 2.3kgs, these wheels should be among the best.
