The S1SC is the first wheel line to utilize HRE’s new proprietary one-piece forged barrel, named FMR™ (Forged Monoblok Rim). The S1SC wheels feature aggressive styling similar to the Monoblok P1SC and employ multiple technical design features for increased stiffness and reduced mass. In typical HRE fashion, particular attention was paid to spoke details, including intersection points and the fastener flange surfacing.

Available in 20” and 21”
