Whats the difference between the gilis and RS4X cranksets?
Many people have asked us what the real difference in performance and functionality is between the Q-Rings/gilis and RS4X cranksets since launching the gilis. The gilis (with SABB cupset) is a cost-effective traditional crankset which allow riders to use standard round chainrings or use Q-Rings chainrings, and configure a system that comes stock with Q-Rings, instead of having to purchase a new crankset and remove the round chainrings. Q-Rings were designed to emulate the biomechanics of the RS4X, without the independent crank arm movement. This way you receive some of the benefits of the RS4X for a lower price tag, and the weight weenies can still sleep well at night knowing that Q-Rings wont make their bike heavier. Both systems orient the maximum effective gear ratio in approximately the same position, a few degrees past the horizontal, in order to benefit from both muscle strength and leg inertia. Both Q-Rings and the RS4X can be adjusted for different riding styles (standing sprin
