    Z Shaped Cranks give you better leverage

    This is awesome... we need to help these guys fund these cool Z shaped cranks which make climbing super easy.

    Z Torque > Home

    They give you longer crank arms but maintain ground clearance!

    (I'm sure the chatter from so called physicists claiming these are a total fraud is just jealousy)

    I'd totally buy, but they used THEN instead of THAN in their tag line. That's a bigger turnoff than smoking... Oh well.

    MIT professor be damned! The physics works here. In fact, I'm going to invent the "ZZ Torque", employing multiple Z's, as many as necessary, for infinite torque.

    Buyers can select from the following models:
    Legs - all around ZZ Torque model with 12 Z's. Most popular model.
    Sharp Dressed Man - top of the line Carbon model with 14 Z's. (Note: not carbon fiber, just carbon)
    Cheap Sunglasses - budget model, only 3 Z's.

    There's a whole lot going on here. I think it needs more suspension type stuff to help climbing...

    Should do the same thing with the arms on the spider. Go faster without needing bigger rings!

    I think those cranks above would really help your cornering.

    These cranks remind me of people who claim bike handling is different (due to leverage) between "angled stem without spacers" and "0 degree stem with spacers" - when the handlebar ends up in the exact same position.

    I feel like this whole thing has to be a troll. Look at the gifts they give you for contributing.

    Leverage = distance between axel and pedal.

    Leverage = distance between axel and pedal. Does not matter how convoluted your crank arm is designed.

    Just get a 180mm crankset to get more leverage................

    Saw this in the comment section of the debunking website:

    "A smaller front wheel means you can simply roll up a small incline with no effort. Make the front wheel small enough and you can roll up quite a steep hill with no energy expended at all."

    Brought to you by the inventor of the Z crank.

    Or how about X cranks. Picture a double ended crank with a slot up the middle in which the pedal can slide from end to end. Then mount the cranks 90* offset so one side is like \ and the other side like /. Then as you push down with say the left foot, once you get down past 90*, you can start pushing down with the right foot. Then when the left foot bottoms out, lift the foot up, the pedal unlocks and slides up the slot in the now vertical crank arm and locks in at the top where you repeat the cycle. You end up with twice the down force on the pedals since two feet are pushing and you get twice the power strokes/revolution (4 instead of 2).

    I've heard of this guy. His last company sold stereos. Their volume went all the way to 11.

    Believing in this crank comes from failing to understand a basic principle.

    You also need to combine it with a smaller rear wheel for better descending.

    That needs to be a sticky in the 29rs forum.

    Now, give him a chance, here. I think the Z crank just needs Bio Pace chainrings to work properly, is all. That will even out the increased torque into a a true constant application of power.

    If they put a DW-Link at the angle, it would also reduce foot fatigue and increase pedaling efficiency. I don't know why that green GT doesn't have a springer seat to reduce the harshness of the ride. I guess some people are just masochists.

    Yes, do those B/P chain rings and don't forget to do the cryo-treatment on all the metal parts. And then use ceramic bearings on he bottom bracket with synthetic Teflon grease and you'll probably need to add a brake to the crank so you can stop it from spinning by itself so you can get your feet on the pedals!

    Well, its easy to laugh over this, but how about guy who avoided FSR patent by placing shock in upward direction and stating that "the force applied to the shock creates upward and forward momentum and helps to get front of the bike over the obstacles."
    Hint: his company in So Cal and his name is not Tony.
    I used to run tubes like you are, but then I got thorn in my wheel.
