The Sturmey-Archer X-FDD puts a dynamo and a 70mm drum brake in one front hub, so the bike's lights and front brake both run from the hub. It suits commuters, tourers and utility bikes that run in all weather.

  • Front dynohub with integrated 70mm drum brake
  • 36 spoke holes
  • 100mm over-locknut dimension, nutted axle
  • A356 aluminium hub shell
  • Sealed cartridge bearings
  • Weight 1220 g

Sturmey-Archer builds the X-FDD as a 6 V dynamo in 3.0 W (HDS73T) and 2.4 W (HDS72T) versions. The drum brake needs a brake cable and lever; the dynamo needs lights made for a 6 V hub dynamo.

Check your fork takes a 100mm nutted front hub and has a way to anchor the brake arm before ordering. Not sure? Send us the make, model and year and we'll confirm.

Sturmey-Archer products are covered against defects in materials and workmanship. Normal wear and misuse are not covered. For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the supplier on your behalf. This is in addition to your rights under the Australian Consumer Law.
