Engineered in Utah, the S3 Wheelset from Mercury Wheels aims to blur the line between a race and training wheelset. The brand prides itself on designing the fastest, most reliable, and stiffest wheelset possible, and that shows with the S3 Wheelset. It's durable enough to withstand everyday rides thanks to a carbon construction, and it maintains a light weight at just under 1500 grams that we can't help but love. An aerodynamic design further improves on the wheelset's racing condition, ensuring speedy acceleration and consistent aero gains.
