PRIMARO SP Hub Set GEN2
PRIMARO SP Hub Set GEN2
PRIMARO SP Hub Set | Straight-Pull Center-Lock
Maximum performance. Minimum weight. Built for speed.
The PRIMARO SP GEN2 Hub Set is the evolution of our proven All-Road Straight-Pull hub. Developed for demanding Road and Gravel riders, it combines an ultra-low weight of just 204 g with high stiffness, direct power transfer and our proven NONPLUS technology.
GEN2 – wider, stiffer, stronger
The key update is the redesigned rear hub geometry: the right spoke flange has been moved further outwards.
This creates a flatter spoke angle on the drive side, resulting in a stiffer and more stable wheel build with improved torsional stiffness. At the same time, the wider flange position gives the hub a more balanced and distinctive appearance.
Key Features:
Only 204 g: 63 g front / 141 g rear
New GEN2 flange geometry for increased stability and torsional stiffness
Straight-Pull design for direct and efficient power transfer
Available in Matte Black & Matte Grey
Freehub options: N3W, HG Road, XDR & MS
NON PLAY system: self-adjusting bearing play for consistently smooth performance
NON VACUUM system: pressure equalization helps protect the bearings from water ingress
NON GAP end caps: minimal gaps for additional protection against dirt and water
Designed for Road & Gravel
