 Please don't say it gives you more torque/changes the position of max power transfer because it doesn't.

Trust me, I'm an engineer.

 might even make it worse.. depending on if they shortened the length of between bottom bracket and pedal spline

 If anything, wouldn't this just weigh more? A straight crank has a lesser mass because it's shorter...

 I'm just becoming an engineer and after taking Statics I can say it looks like it is made to better resist bending moment in the middle (like the bow in a big ol' steel bridge), but I think they need a 2 force member to go straight between the BB and the pedal spindle to actually have any effect? I bet its just to look cool (although maybe the designer thought it has better ergonomics for where your ankles/shins touch on whips or something.)

 I am not an engineer, but if you happen to pay attention to the back crank, which would really help, the pedals are normally straight across, but with these cranks they are not. So there is some reason these are designed this way.

 good call dude. (plus props for awesome statement of the obvious).

 I´m with you... I don't believe what they say in their page www.e-chien.com.tw/english/index.php

The axles are in the same position as in normal cranksets

 looks like it might work as a bash guard, or similar, that might not be intentional though

 thats also a 50 tooth chainring, or about 50 anyway, so its could be a road part thrown at and XCO bike.

 But there not even on straight?

 i agree thay must be harder to put on straight do to the shape haha

 With its aerodynamics, it allows those who cant shift much less drag from the traditional block style crank. Works amazingly well when paired with a set of homemade pedals made from whisks.

 It may look cool, but there is no advantage compared to normal cranks. So why create something which probably uses more material than a straight crank?

 GAY.

 Obviously it sure ain't straight!

 Jhou, Best comment ever!

 This is a stupid design. The position of both pedals is the same as a normal crank. If anything, the crank will keep hitting rocks in a rock garden. This is the best design to have a shitty looking crank after the first ride. Looks heavy too.

 if any thing it looks like it would put more spring in the crank and being a DH guy thats the last thing i would want .. besides in the pic you can see that its realy easy to inproperly install them in balance .... so ya more cons to pros poor disign

 looks like these weren't installed right, the non-drive side pedal should be at the top of the rotation.

According to this review (sorry in Japanese), its weight is 1427g w/ BB and chainrings. It's incredibly heavy.

 Not again... This crank design should stay where it belong, in the bicycle museum of bad ideas.

 Impressionist crank arm. Comes with a melted pocket watch.

 hey man this design looks reasonable,especially for 29er I can't wait to try
  • 3 0
 i just don't see the point in it...
  • 1 0
 it would be more heavy though.. why would you put it on a 29er
  • 2 1
 honestly it just looks like it would make the transfer of energy less efficient.
  • 3 1
 It's the same... In what energy transfer is concerned it's the distance between the BB's center and the pedal center...

 whoah, interesting. it has been quite some time since ive taken physics. anyways, thanks!

 they can also be used to turn soil in your garden come spring time.

 It has to work because, for sure, it's very expensive due to plenty of material used Big Grin Logical? Big Grin

 I belive you buddy. It looks awesome!

 I can't really see any advantages for this except for the look, and the unique factor....

 won't this just be more heavier ?
