Testing 29" VS 27.5" Downhill MTB Wheels | UCI MTB World Cup: Lourdes Practice Day

The great mountain bike debate of the 21st century has found it's way into the downhill scene. The all-mighty 26 inch wheel and it's ever-radical form and function is being challenged by it's younger (yet, bigger) brother, the 29 inch wheel. Who's faster when gravity is on your back? We're not sure. And we're not sure these guys know either, but damn we're curious to find out! See how the 29ers did by watching the full Lourdes replay on Red Bull TV!
