Grand Cru Fixed Hub, Rear
The Grand Cru fixed gear hub has high quality Japanese sealed bearings. The axle is chrome plated for durability and hollow to save a little weight. Proper track nuts are included. They are "fixed" threaded on both sides so you can use a cog and lock ring or a freewheel on either, or both, sides.
The hubs come spaced at 120mm, but include spacers to make them 126mm, 130mm, and 135mm.
