I Beam Spokes is the most significant new feature we’ve added. Weight is reduced by CNC machining material out from the sides of each spoke. It’s expensive and avoided by almost every manufacturer, but we’ve made it affordable through volume production.
By saving weight elsewhere, we’ve added extra material where it counts. We beefed up the barrel’s inner lip to better handle the abuse from the street and track.
Multiple face profiles are utilized to maximize spoke concavity and reduce weight on the SM-10 design. To maintain our great brake clearance the profiles and spoke curvature of this wheel is just like our EC-7 design.
All APEX wheels feature Flow-Formed construction that utilizes rotary forging to produce a strong and lightweight barrel. The SM-10 is no exception.
True JWL and VIA Certification. You won’t find tricky terminology to cover up a lack of testing here. We always do real world crush testing and get real certificates from the Japanese Government again to prove it, just like we’ve always done.
