• PURA ONE 4540 – The SYNCROS Capital SL Ultra Challenger

    United in Carbon, Unmatched in Performance.

    FITLITE PURA ONE 4540 : Monocoque carbon construction—light as hell, stiff as steel, fast as ever.

  • PURA ONE 4540 – The SYNCROS Capital SL Ultra Challenger
    One-Piece Carbon Construction
    The rim, spokes, and hub shell are molded together in a single step. No bonding between parts — just a seamless carbon structure that’s light, stiff, and fast.
    Carbon Spokes, Fully Integrated
    Each side uses four continuous carbon spokes that loop and cross, forming a unified, responsive system.
    Bonded & Bolted
    Beyond bonding, we reinforce the hub connection with 8 titanium bolts — ensuring long-term strength and zero slippage under load.
    Precision-Built
    Every wheel is factory pre-tensioned, true, and ready to ride — no tuning needed.

    It’s so light, it feels illegal

  • S4540W, Fulcrum Sharq performance, redefined.
