Would you prioritize high-end wheelsets over other upgrades for your gravel bike?
Vision has introduced the SC 45 i30, a new gravel wheelset optimized for modern wide tire profiles. Professional cyclist Marius Røren utilized the wheels to secure a fourth-place finish at The Rift gravel race in Iceland.
Why it matters
This release reflects a shift toward wider internal rim profiles in gravel cycling, which aim to improve tire stability and ride quality. Understanding these technical specifications helps riders determine if current equipment matches their specific terrain needs.
The SC 45 i30 wheelset features a 45mm rim depth, 38.5mm external width, and a 30mm internal hooked profile. These technical figures characterize a design intended for high-volume gravel tires, though real-world weight variances were observed in testing.
The players
Vision
A manufacturer of high-performance cycling components including aero wheelsets, handlebars, and drivetrain parts.
Marius Røren
A professional gravel cyclist who recently competed in The Rift using new prototype equipment.
The details
The wheelset utilizes Vision V-200 hubs equipped with sealed-cartridge bearings and press-fit end caps for simplified maintenance. Power transfer and lateral stiffness are supported by a 2:1 cross spoke pattern featuring bladed aero spokes. The internal hooked profile is specifically engineered to provide a stable foundation for the wider gravel tires common in modern endurance riding.

Health Landscape
This development tracks the evolution of gravel equipment tested at The Rift, a known benchmark for extreme off-road racing conditions. The launch follows the broader industry trend of adopting wider internal rims to maximize tire stability for endurance performance.
Riders should consult with a professional bike fitter to ensure the 30mm internal rim width is compatible with their current frame and desired tire pressure. These technical choices primarily influence handling stability and comfort over long, varied gravel surfaces.
The takeaway
The move toward wider internal rim widths reflects a priority for tire support and ride compliance in demanding terrain. Riders interested in equipment upgrades should evaluate how these rim measurements integrate with their specific bike's handling characteristics during a local shop consultation.
