Sturmey Archer X-RD5 Summit Hub Gear with 70mm Drum Brake

In stock

£157.99 incl tax

This hub from Sturmey incorporates a 70mm drum brake.

Drum brakes are efficient - sealed from the mud and wet of the good old British roads - they will work better than than the average rim brake. They will also last longer as they are shielded from the mud and grit that wears normal brake pads down.
