Wheel compliance, weight and aerodynamics. Three attributes that can transform a bike's performance and ride quality, and three things we're constantly exploring through the latest innovations in wheel technology.
Enter the Sparrow 50 Gold.
Built with ultra-light Dyneema spokes, these wheels are engineered to take the sting out of rough terrain while delivering the stiffness and responsiveness you'd expect from a performance wheelset.
The ride is so smooth that grooming and personal hygiene may be performed in transit.
We do not endorse operating sharp instruments while cycling.
Side effects may include winning.
The numbers:
1,298g | 50mm deep | 30mm internal | £2,159 RRP
Berd reports 14% less aerodynamic drag than its previous Sparrow and approximately 5 watts saved at 30km/h through vibration damping.
