The Ace takes the fast, nimble concept of the single speed and raises it. The Ace is the only belt drive single speed featuring a Gates Carbon Drive and flip-flop rear hub that allows you to adjust how you ride—fixed or freewheel. We’re dealing up The Ace in two suits: The Ace of Clubs is for recreational riders and commuters who value simplicity and no-nonsense reliability, and The Ace of Spades is for performance riders who want maximum responsiveness. There's no limit to The Ace! Don't be caught without a multi-tool! 174HUDSON Multi-Tools available here .
