The NJF speed spoiler is the only true tool to unlock free watts*.
Leveraging perfect aerodynamics by applying this mini spoiler to the bridge, fender, or frame of ANY bike (fixed gear, ATB, road, or even e-bike) you convert all that chain slap, brake rub, grinding gears, and jank into PURE FREE WATTS.
Don't believe me? Buy one and find out for yourself.
Designed to be bolted to your brake bridge, or zip tied to your fender, saddle, or whatever other nonsense you got going on.
Comes in a pack of 2 because you should never have just 1 bike.
