Extreme power through your pedals

The NEW Extreme RR has an Ultralight Carbon 15 sole made of 100% unidirectional carbon combined with a reinforced layer. With a stiffness index of 15.0, it's the best-performing Northwave sole ever.  It is Northwave Speedplay adapter compatible for the lowest stack height between foot and pedal.

Made with Xframe® patented construction and ultralight next generation materials that are only 0.5 mm thick, the upper transfers every watt of power and provides the snuggest, even fit with no pressure points.

Extreme RR features the SLW2 dial, the only one with step-by-step and full release in a single button.  It has an integrated heel system containing directional fibre which prevents any slipping.

The box includes two footbeds with a stiffened dual density design: Pro Regular Fit and Pro Slim Fit which features an extra 2 mm toe insert for narrow feet.  And most importantly, the Extreme RR is ultralight at just 220 g!
