Shimano chains. Asymmetric, Directional etc.
Hi there.
Just wondering what the difference is between a directional and asymmetric chain. I've always used directional chains and kept the Shimano logos facing out. How does an asymmetric chain differ? Does it being 'super narrow' have an effect?
I ask because I picked up a Shimano Dura Ace CN HG 901 chain a couple of months back to replace a worn 5800 chain. The chain was fitted as usual with the logos facing out. The chain runs well on the small chainring but its not as smooth on the big chainring.
Would appreciate someone explaining the difference between the likes of Dura Ace HG 900 and HG 901 or 105 HG 600 and HG 601.

Because the effect on chain pull is different on a bike with asymmetric stays.
As explained by Pinarello.

Ummm...
Milemuncher once again confusing marketing hype with science fact.. :roll:
OP - I would suggest you disregard this guy's replies - he's on his third user account now...
AFAIK the HG 901 relates to chains compatible with E_bikes and MTB's. Where a Q appears with the chain code refers to it coming with a quicklink. The HG 901 is the updated version of the HG 900 to cope with e-bikes. HG 901-11 is the asymmetric code.
I think it must be deliberate, as nobody can be that ignorant by chance. To claim that asymmetric chains are intended for bikes with asymmetric chainstays is to completely misunderstand what Shimano means when it uses the word. The fact that Pinarello also uses the word to describe an aspect of its frame design is incidental and completely irrelevant in this context.
