Once again a fookin MEGA tight spot in the new chain on my latest build last night. Every build this happens! :tickedoff: All seems straight, spins nicely, lined up well, chain on, then sh*t. I'm guessing if each component is even slightly out/bent etc then it's gonna happen. ???

Do you have a chain tool? Try pushing the pin through a nic ever so slightly either way you may find its a nads cock out.....ive had this a few times if the chains been split the pin may not be in its original place :daumenhoch:
-
chain ring bolts too, if that's not on straight you end up with a nice oval rotation. :daumenhoch:
-
I know you'll have checked but :)
Chain-line - all straight from the freewheel to sprocket?
Rear wheel aligned correctly?
Has the sprocket bolt (if they're 3-piece cranks) pulled the sprocket out of line slightly?
Bottom bracket in flush?
Sprocket teeth not worn?
Chain off the bike - all links move freely?
-
theres also the dreaded freewheel "float" that ya cant do f'all about. if ya spin back wheel you can sometimes see the freewheel bobbing up n down slightly, that doesnt help ::)

Cheers chaps, I'll check all above tonite. :daumenhoch:
Chain looks like a feckin washin line in one place when adjusted at the tight spot!! I will not be beat!!! :crazy2:

Go chainless. :buck2:
-
undo everything and let the chain find its correct alignment, then do it all up in the right place
