In modern cycling, versatility is no longer just an option, but a fundamental requirement. Today’s riders demand equipment that performs without compromise on a variety of terrains. With the SC 48 i25, VISION presents a wheelset that redefines the balance between aerodynamic performance, stability and everyday practicality.
As part of the SC (Service Course) series, the SC 48 i25 epitomises the VISION philosophy par excellence: first-class carbon technology at a competitive price. VISION calls the result the ‘smart choice’ – a wheelset that meets the specific requirements of road and gravel cyclists alike.
A new benchmark for aero-gravel performance
At the heart of the SC 48 i25 is the full-carbon rim, with a rim depth of 48 mm and a generous internal rim width of 25 mm. This configuration was specifically chosen to create a hybrid platform that performs just as well on tarmac as it does off the beaten track.
The shallower aero profile ensures efficient airflow and reduced drag at higher speeds. At the same time, the wide rim channel provides optimum support for modern, high-volume tyres. This combination improves grip, comfort and control – crucial factors when transitioning from smooth tarmac to unpredictable gravel sections.
The SC 48 i25 It was designed as a genuine ‘aero-gravel’ solution and gives the rider the confidence they need to tackle varied terrain without losing speed.
CFD-aided development
The development of the SC 48 i25 is based on advanced computational fluid dynamics (CFD). Drawing on years of expertise in aerodynamics, the VISION engineers analysed over 300 rim profile variants from the Road and Gravel categories. The aim was to find the optimal balance between aerodynamic drag, stability and weight.
The final 48 mm profile was chosen not only for its aerodynamic efficiency, but also for its predictable handling at different angles of attack (yaw angles) – particularly when combined with wider tyres. This focus on crosswind stability is crucial in real-world conditions, where wind variability and group dynamics influence performance. The SC 48 i25 remains stable when cornering, sprinting and braking, and inspires confidence in every situation.
Designed for reliability and performance
As well as aerodynamics, the SC 48 i25 has been designed with durability and ease of maintenance in mind. The wheelset features 24 aero blade spokes in a 2:1 lacing pattern, which optimises power transfer and structural rigidity.
At the heart of the system is the tried-and-tested V-200 hub, which has been fitted with an improved pawl system for optimised engagement and greater reliability. Thanks to the redesigned hub, it is no longer necessary to adjust the bearing preload. The integrated press-fit end caps make maintenance easier and more user-friendly.
The Centre Lock mount ensures compatibility with modern disc brake systems, whilst various freehub options (including Shimano, SRAM XDR, Micro Spline and Campagnolo) guarantee seamless integration with current drivetrains.
Designed to meet modern requirements
Weighing 1,590 grams per pair, the SC 48 i25 A balanced combination of lightweight construction and robustness. The tubeless-ready design also allows you to ride with lower tyre pressure. This enhances comfort and minimises rolling resistance and the risk of punctures off-road. Thanks to this versatility, the wheelset is ideal for a wide range of riders – from endurance riders seeking aerodynamic advantages to gravel enthusiasts who demand a fast and stable setup.
Uncompromising performance
With a retail price of €1,349, the SC 48 i25 offers high-end engineering and aerodynamic design at a competitive price – without compromising on quality. This achievement is based on over 15 years’ experience as a trusted technical partner to professional teams at both WorldTour and Continental level, where performance-oriented design has always been the top priority.
Smart details, real benefits
Innovation goes beyond performance. The SC 48 i25 features a handy function that enhances the overall experience: a QR code laser-engraved directly onto the hub housing. This provides instant access to an online spare parts manual, thereby simplifying maintenance and servicing.
Backed by a global service network – comprising four main branches and 40 service centres worldwide – VISION guarantees long-term support, wherever your journey takes you.
The ‘Smart Choice’
The SC 48 i25 is more than just a wheelset – it is the answer to the growing demands of modern cycling. By combining aerodynamic efficiency, stability and versatility, VISION delivers a product that performs across all disciplines. Whether you’re riding at high speeds on the road or pushing the limits on gravel, the SC 48 i25 is a reliable and forward-thinking choice – designed for performance, built for everyday use.
