Reserve 30|SL Carbon Wheelset with DT Swiss 350 Hubs – Lightweight Trail Performance
The Reserve 30|SL paired with the DT Swiss 350 DEG (or the DEG DF variant) represents the cutting edge of carbon trail wheels for 2026. While the "SL" (Super Light) designation traditionally implies a cross-country focus, Reserve has engineered these with no rider weight limit, making them a formidable choice for aggressive trail riders who want to shed rotational mass without sacrificing the "bombproof" reputation Reserve is known for.
The introduction of the DEG DF (Degrees of Freedom) hub is a game-changer for high-pivot bikes, as it allows you to mechanically tune out pedal kickback at the hub level.
The Reserve 30|SL is a 1,702g carbon wheelset that defies logic. It features a shallow 19mm rim depth designed specifically for vertical compliance, allowing the wheel to track through chatter rather than bouncing off it. This "engineered flex" reduces rider fatigue and increases cornering grip.
DT 350 DEG: Features a massive 90TT ratchet system providing a crisp 4-degree engagement. It uses larger bearings and a reinforced hub shell compared to the standard 350, making it e-bike compatible and significantly more durable.
DT 350 DEG DF (Degrees of Freedom): This is the ultimate "High-Pivot" upgrade. It allows for a selectable amount of free rotation (0-deg, 1-deg, or 20-deg) before the hub engages. This effectively isolates the suspension's "chain growth" from your pedals, providing the smoothest possible descent oon bikes with noticeable opedal kickback from chain growth.
The 20° Setting: By choosing the DEG DF hub and setting it to 20-degrees, you essentially give the suspension a "free pass" to move through its travel without the chain tugging at your feet.
The Result: Your suspension will feel noticeably more "coil-like" and plush, even with an air shock, as it is no longer fighting the drivetrain.
The XC Mode: On the fire-road climb back up, you can technically switch back to 0-degree for instant power transfer, though most riders find the 10-degree "Trail" setting the perfect set-and-forget balance.
Ultra-Lightweight Carbon: Optimised for trail riding with a weight of approximately 1,743g (29" wheelset with DT 350 hubs), boosting climbing speed and acceleration.
DT Swiss 350 Hubs: Equipped with the reliable DT Swiss 350 Boost hubs for excellent durability and low-maintenance performance.
Asymmetric Rim Design: Improves spoke bracing angles and equalises spoke tension, resulting in a stronger, stiffer, and more dependable wheel build.
30mm Internal Width: Perfectly supports 2.3" to 2.6" trail tyres for a better profile, increased grip, and confident handling.
Internally Reinforced Spoke Holes: Material is only added where it’s needed (around the nipples), keeping the rim weight to a scant 449g
Fillmore Valves: Included as standard, offering 3x the airflow of a Presta valve and eliminating sealant clogging
Tubeless Ready: Features a redesigned rim bed for easier tubeless tyre installation and supplied with Reserve Fillmore high-flow valves and rim tape.
Uncompromising Lifetime Guarantee: Ride without hesitation thanks to Reserve's industry-leading warranty.
