THE AWESOME ROTOR CRANK!

	What is Rotor System and how does it work? Rotor is an innovative pedalling system eliminating the dead point. The dead point on most recumbents is the void occurring when the pedals are horizontal (one in front of the other), which is a moment at which neither leg can transmit any power.
	The dead point limits your performance, causes tendonitis and injuries to the knee
	The cranks are independent in such a way that they are not aligned at a fixed 180º. This way, one pedal never coincides with the other, thus avoiding power vacuums. Such an effect is achieved by the use of independent cranks that are synchronised by means of an exocentric axel and two rods, which vary the development during the pedalling cycle.
	Rotor achieves a real increase in power of up to 16% (equivalent to an average advantage of 3 minutes in an hour), as well as a reduction in lactic acid and cardiac effort.

ROTOR REVIEW ON 'BENTRIDER

Another great review on ROTOR Cranks, this time at the USA website www.bentrideronline.com. The first of three reviews was just posted this week by prestigious journalist and ‘bent cyclist, BRYAN J. BALL. Some of Bryan's comments are quite similar to what is being said by so many other cyclists, including:

"On the very first ride I found myself pushing high gears and climbing a bit faster. After 200 miles, I've found myself climbing MUCH faster ... With the Rotors I can climb up some steep local hills at 11.5km an hour versus 9.5 without."

"My knees feel great on the Rotors ... My cadence has dropped back into the low to mid 70's but my knees still feel much better than they did pre-Rotor."

"After 200 miles on them I do honestly feel like they are worth it for me. I've struggled with knee problems and my spin for years now. Anything that will make my knees last a bit longer and help me go a touch faster is a bargain in my book."

"...Rotor Cranks are what may be the biggest performance enhancing add-on available on the market Today."
