Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Also called a sleeping hub, the DH-1 slides into rear dropouts and replaces the rear wheel for chain cleaning and transport. Works with all derailleur and ⅛in. chains.

  • Allows the bike to shift
