Whether you're lapping the terrain park or heading into the backcountry you need a pair of pants that let your legs breathe. The Oakley Haver Softshell Pant can make the difference between a super-fun challenging aerobic workout and a hot clammy miserable experience. More than just breathable fabric the Haver Softshell comes equipped with bulk-free invisible inner thigh ventsthat allow you to dump heat in a hurry. Oakley's waterproof breathable Hydrogauge 15 membrane keeps water from getting inside the pant and allows sweat vapor to escape.The Haver's fit is women-specific slim for a look that's all-the-way feminine. Adjustable waist tabs allow you to customize the fit and belt loops let you fine tune the fit or just accessorize. The silicone gripper at the waist band ensures that anything that's supposed to be tucked in stays tucked in and stretch boot gaiters keep snow from getting inside. For the final touch Oakley added lower leg zippers to make the Haver easier to get over your boots or to just leave open for style.
If you've been around mountain bikes for a while you certainly remember the short-lived fad of BioPace chainrings. And although the theory behind them is relatively the same the Rotor MTB Double Q-Ring Set 110x74 BCD is an entirely different beast. These elliptical chainrings help to maximize your power output by reducing the time spent pedaling through the dead spot at the top and bottom of your pedal stroke. Which means that you'll put down more power with less effort.Yes we're talking about free speed. The theory behind Rotor's elliptical Q-Ring is fairly simple -- when pedaling your legs naturally produce the greatest amount of power on the downstroke and they produce less power when your feet are coming up over the top of the rotation. This position is also known as the dreaded 'dead-spot.' The ellipse is shaped so that as you pedal through this dead-spot. How? Well the diameter of the section that's pulling the chain is that of a slightly smaller chainring which spares you effort as well as reducing the time that's spent in this sub-optimal portion of the pedal stroke. And as you get into the most powerful portion of your pedal stroke the diameter of the chainring increases effectively mimicking the roll-out of a slightly larger chainring. This all adds up to more time spent where your pedal stroke is most efficient and less time spent where it isn't. And although its counterintuitive it feels like you're spinning smoother circles than with a traditional round ring. The 7075-T6 aluminum that the Q-Rings are machined from is a hardened alloy that promotes long wear life. Basically these rings are built to put in the miles. And the shifting pins make for quick shifts even under power. These chainrings feature a five-bolt pattern with a 110mm BCD for the outer ring and a 74mm BCD for the inner ring. These are designed specifically for Rotor's 3D mountain bike cranksets and fitting them with other 110mm BCD cranksets may require slight modif...
