BERD SPARROW50 GOLD | CARBON GRAVEL WHEELSET
1,298g. 50mm deep. Engineered for speed, comfort and control.
The Berd Sparrow50 Gold brings together aerodynamic carbon rims, ultra-lightweight Dyneema spokes and precision-engineered hubs to create a gravel wheelset that refuses to compromise.
Designed for performance gravel racing and ultra-distance riding, the Sparrow50 Gold combines aerodynamic efficiency with vibration-damping technology to help you maintain speed and reduce fatigue when the terrain gets rough.

AERODYNAMICS WITHOUT COMPROMISE
The Sparrow50 Gold features a 50mm-deep carbon rim developed to deliver aerodynamic performance on modern gravel tyres. Its 38mm external width and 30mm internal channel provide a wide platform for high-volume rubber.
Berd reports a 14% aerodynamic improvement over its previous-generation Sparrow wheelset. The rim has been optimised around 45–55mm tyres, making it particularly well suited to modern performance gravel bikes.
DYNEEMA SPOKES. A DIFFERENT KIND OF COMPLIANCE.
Conventional steel spokes transmit high-frequency vibration through the wheel. Berd PolyLight spokes use ultra-high-molecular- weight polyethylene fibres, commonly known as Dyneema, to introduce viscoelastic damping.
This technology dissipates vibration energy, helping to reduce the harshness transmitted through the bike. The result is a smoother ride over rough gravel, washboard surfaces and broken terrain.
Each spoke weighs approximately 2.4g, contributing to the wheelset's exceptionally low overall weight.
LESS VIBRATION. MORE EFFICIENCY.
Berd reports a 5-watt rolling-efficiency benefit at 30km/h from its vibration-damping spokes, based on independent testing by John Karrasch.
By reducing vibration-related energy losses, the Sparrow50 Gold is designed to help riders maintain efficiency and comfort across demanding gravel terrain.
BERD TALON ESL-R HUBS
At the centre of the wheelset are Berd's Talon ESL-R hubs, featuring a lightweight 36-tooth ratchet freehub and precision-machined Tri-Coat aluminium freehub body.
Equal Spoke Length technology uses identical spoke lengths across both sides of both wheels, simplifying spare-spoke management and servicing.
