Power in the back, looks in the front. The G3 Front Disc Hub is the perfect match for the PowerTap G3 Rear Disc Hub. From the smooth design to the durable shell, the G3 Front Disc Hub provides all the stopping power of its rear counterpart - and looks just as good.
We've worked hard to offer the lightest, most accurate and easiest to use power meters available - but none of that matters if it doesn't work every single day. To prove our commitment to quality we’re pleased to offer a two year warranty worldwide on any PowerTap branded hub.
