The Seido Geon is a lightweight, race-ready aluminum wheelset for gravel and all-road bikes in 27.5 inches (650B).
The asymmetric rims with a 23 mm internal width, 24 straight-pull spokes each, and triple-butted Pillar spokes combine low weight with high stiffness and rapid acceleration.
A ratchet freehub system ensures direct power transfer and reliable operation, while the tubeless-ready rims enable a modern tubeless setup.
Highlights:
- Lightweight aluminum wheelset: the set weight of 1524 g supports rapid acceleration
- Ratchet freehub system: enables direct power transfer and high reliability
- Asymmetric rims: support a stiff and balanced wheel build
- Straight-pull spokes: 24 triple-butted spokes per wheel provide high stiffness with low weight
