Description
Specifications

Experience the perfect blend of lightweight performance, durability, and modern engineering with the Seido Sinus Wheel Pair 650B / 584. Designed for versatile trail, gravel, and endurance riding, these tubeless-ready wheels deliver exceptional handling and reliability on any terrain.

Materials & Construction

Constructed from premium 6061-T6 aluminum alloy, the Seido Sinus wheels boast a robust yet lightweight build, ensuring optimal strength-to-weight ratio. The asymmetric rim design features a 25mm internal width, increasing tire stability and grip, especially suited for tires ranging from 30-50mm widths. The sleeved joint construction enhances durability and provides a clean, finished look.

Performance & Engineering

engineered for high performance, these wheels weigh approximately 1743 grams per pair, making them an excellent choice for riders seeking agility without sacrificing strength. The 24mm wheel depth optimizes aerodynamic efficiency while maintaining lightweight handling. The hubs feature 36 spoke holes with J-bend spokes, offering excellent tension balance and ride quality.

Components & Technology

Equipped with a 12mm thru-axle (TA) compatibility, these wheels deliver enhanced stiffness and precise handling. The sealed Seido TPI hubs utilize a Shimano HG freehub body, with options for XDR and Microspline adapters, ensuring compatibility across a wide range of cassette systems. Pre-installed tubeless tape and aluminum tubeless valves simplify setup, allowing you to quickly convert to tubeless for reduced flats and lower rolling resistance.

Style & Use Case

With their sleek black finish and center-lock disc brake compatibility, the Seido Sinus wheels are ideal for mountain biking, gravel adventures, and bikepacking. Their versatile design supports a variety of riding styles, providing the confidence and efficiency needed for both technical climbs and high-speed descents.

Innovative & Differentiating Features

The asymmetric rim design enhances spoke tension balance, resulting in increased durability and wheel longevity under demanding riding conditions. The tubeless-ready hooked clincher design, combined with pre-installed tape and valves, ensures excellent sealing and maintenance ease. Additionally, the compatibility with multiple freehub options (XDR, Microspline available separately) offers flexibility for future upgrades.
