Innovation in Gravel Wheel Design: The 9th Wave SandStone SL32
9th Wave has introduced its cutting-edge SandStone SL32 wheelset, marking a significant advancement in gravel cycling technology with the integration of 32-inch wheels designed for enhanced aerodynamics. This new wheel size is gaining traction within the cycling community for its potential to smooth out rough terrain and maintain speed more effectively, crucial aspects for competitive gravel riding. The SandStone SL32 wheelset is meticulously engineered with a 52mm rim depth, providing considerable aerodynamic benefits, and a generous 37mm internal rim width. This wider internal width is specifically chosen to support tires of 50mm and larger, ensuring optimal tire performance by reducing sidewall deformation during cornering and at lower tire pressures, thereby offering superior grip and control on challenging surfaces.
Addressing potential concerns regarding lateral stiffness often associated with larger wheel diameters, 9th Wave has implemented a multi-faceted approach in the design of the SandStone SL32. The deep rim profile allows for spoke lengths comparable to those found on 29-inch wheels with shallower rims, contributing to overall wheel rigidity. Furthermore, the wheelset utilizes 28 spokes, an increase from the typical 24 spokes seen in many gravel wheels, which significantly boosts lateral stability. The incorporation of Boost spacing improves the bracing angle, enhancing the wheel's structural integrity. Additionally, 9th Wave’s proprietary ART asymmetric rim design ensures an even distribution of spoke tension, further optimizing durability and performance. These combined features aim to deliver a robust and responsive wheelset capable of handling the rigors of modern gravel courses.
Performance and Pricing: Exploring the SandStone SL32 Options
The SandStone SL32 wheelset from 9th Wave is engineered to deliver exceptional performance, specifically targeting the unique demands of gravel racing and challenging off-road conditions. The standard version of the wheelset, equipped with DT Swiss 240 EXP Boost hubs, boasts a competitive weight of 1,579 grams and is priced at €1,999. This configuration is designed for serious gravel riders seeking a balance of lightweight construction, aerodynamic efficiency, and robust durability. The thoughtful selection of components, including the reliable DT Swiss hubs, ensures consistent performance and longevity, making it a compelling option for those looking to upgrade their gravel bike's capabilities. The design emphasizes sustained momentum and stability, critical factors when navigating varied and often unpredictable terrain over long distances.
For riders demanding the absolute pinnacle of performance and a marginal weight advantage, 9th Wave offers the SandStone SL32 LTD. This premium version shaves 73 grams off the standard model, achieving an even lighter total weight, primarily through the use of DT Swiss 180 Boost hubs featuring ceramic bearings. The LTD edition also incorporates Alpina aero spokes and a distinctive silver finish, signaling its elevated status. Priced at €2,299, the SandStone SL32 LTD is tailored for elite athletes and enthusiasts who prioritize every possible performance gain. The ceramic bearings reduce friction, providing a smoother and more efficient roll, while the specialized aero spokes further enhance the wheelset's aerodynamic properties. Both versions are available for pre-order, with deliveries anticipated to commence in September 2026, offering riders an opportunity to experience this advanced gravel wheel technology.
