Helix SL Rim: Lightweight Performance for Trail & All-Day Adventures

Designed for riders seeking a balance of strength and agility, the Helix SL Rim delivers precision-engineered performance tailored for demanding trails and endurance rides. Crafted from durable aluminum alloy, this midweight rim strikes an optimal equilibrium—offering robust durability without compromising on speed or agility. Its 22mm internal width supports modern wide-profile tires for enhanced traction and stability on technical terrain, while tubeless-ready compatibility simplifies setup and enhances puncture resistance on rocky or root-filled paths.

Key Features & Benefits:
– Pinned & Sleeved Construction: Reinforced joints ensure seamless strength across high-stress zones, ideal for aggressive riding styles.

Why Choose Helix SL?
Compared to heavier alloy rims, the Helix SL’s midweight design reduces rotational mass for snappier acceleration—critical on long climbs or sprint sections. Unlike non-tubeless options, its sealed system cuts maintenance time while boosting confidence on loose or sharp-edged trails. At 488g per rim (29″ size), it outperforms bulkier alternatives without sacrificing rigidity under hard braking or cornering forces.

Ideal For:
– Mountain bikers tackling all-mountain or cross-country routes
– Riders upgrading wheels for tubeless setups without overhauling budgets
– Trail enthusiasts prioritizing weight savings without compromising reliability
