Speedline Parts | Killer Buzz Hubsets 20mm Front / 3/8" Rear

We know the current trend is to be silent and seek instant engagement. But there's something to be said for the LOUD hubs. And these hubs are most definitely that, LOUD!

The new Speedline Killer Buzz Hubs feature our Worm Drive system to give you near-instant engagement. But they don't have the drag that other instant engagement hubs always seem to have. They're designed for minimal rolling resistance. These hubs roll faster when you're off the gas and coasting. And let's face it, how often are you actually PEDALING the ENTIRE track?  Be honest... we all coast more than we pedal. So shouldn't that be where you want the advantage?

Experience increased cornering speed and rhythm straight flow with the Speedline Killer Buzz Hubs!
