So that's why cycle clips come in pairs. I always wondered why, now I can die a happy man.

thats cheatin

Like the Clemtwin crank idea, but with Profiles.
That would be pricey for  2 drive side cranks.

Wasn't it really difficult to get both chains equally tensioned, so one chain would always end up coming off when the frame flexed?
I recall reading an article a while back.

Agree about the cycle clips

would it give more power , surely not

Maybe, but if so it's totally wasted by using Z Rims   

[lazychubs]

spesh if its a flip flop hub as he wont be able to stop peddling
even when the pedal falls off as its on the wrong side lol

I read that the idea was to reduce power lost to flex, because a single chainring tends to pull the wheel and frame to one side.
But technical problems (i.e. the chain(s) tending to come off) meant it wasn't very practical.
There's a thread on vbmx about it (not the bike above, but clem cranks in general).

I just think its silly. 

[duncan]

Yep, a solution looking for a problem.

[sonic-1]

well defo diffrent , thinkin about it yer would lose power to the rear wheel as more drive train yer have = more power lost

[Waxintaxin]

its like 2 crank shafts and still using the 1 engine, friction would play a part and so would the general resistance of the chain and the sprocket , would that flex outway that .

Fuk knows and quite frankly it would fuk up both inside legs of me trousers so i dont care.

techie issues aside I think it looks the nuts
