The Reserve 30|HD is the heavy-duty carbon powerhouse of the Reserve range, designed for ASTM Category 4 (Enduro) and Category 5 (Downhill) use. While the "SL" variant focuses on compliance and weight, the 30|HD prioritises lateral stiffness and impact resistance for aggressive gravity riding and e-MTB applications.
The integration of the DT Swiss 350 DEG and the DEG DF (Degrees of Freedom) system provides a mechanical solution to pedal kickback directly within the hub.
The Reserve 30|HD is engineered to be "overbuilt." It features a deeper 20mm profile compared to the SL, providing the structural bracing needed for high-speed cornering and heavy impacts. The rim utilises an asymmetric design to balance spoke tension and reinforced "square" sections around the spoke holes to prevent pull-through under extreme loads.
DT 350 DEG (Standard): This hub utilises a massive 90T Ratchet DEG system, providing an ultra-fast 4-degree engagement. It is designed with an oversized ratchet diameter to increase the contact patch, significantly improving reliability under high torque.
DT 350 DEG DF (Degrees of Freedom): This version includes a specialised ratchet and thread ring kit that allows the hub to float before engaging. You can manually adjust the "float" to 0-degree, 10-degree, or 20-degree by simply pulling the freehub body and realigning the internal ratchet. This isolates the suspension's chain growth from the cranks, providing a "chainless" feel on descents.
Ultimate Durability: Carbon rim designed for high-impact forces, ideal for enduro and all-mountain use.
High Engagement Hub: Equipped with the DT Swiss 350 hub featuring the 90T DEG (Star Ratchet Upgrade) for lightning-fast power pickup.
Optimised Wheel Build: Asymmetrical rim profile ensures equalised spoke tension, resulting in a stronger, stiffer, and more reliable wheel.
Tubeless Ready Design: Redesigned rim bed simplifies tubeless tyre installation and provides a secure bead lock.
Engineered for E-Bikes: The 30|HD is fully e-MTB rated, with the 350 DEG hub using reinforced internals to manage the torque of modern high-power motors.
Asymmetric Carbon Rim: $4 ext{mm}$ offset improves the bracing angle of the 28 J-bend spokes, creating a more durable wheel build.
Redesigned Rim Bed: A shaped inner profile makes seating stubborn tubeless tyres much easier, even with a floor pump.
Fillmore Valves: Included as standard; these high-flow valves are clog-proof and offer $3 ext{x}$ the airflow of standard Prestas.
Lifetime Warranty: Covered by Reserve's exceptional, no-nonsense lifetime warranty.
Optimal Tyre Fit: 30mm internal width is perfect for 2.3" to 2.5" mountain bike tyres.
