I've started getting a weird click from my chainline recently.

Every second revolution of the cranks there is a small but definate click and a bit of tension in the movement.

I've checked the chainring bolts are tight and the chainline is straight

The BB is a pretty new Miche Primato. But I'm guessing it can't be that as there would be a click every revolution of the cranks.

My only guess would be that there is a stiff link in the chain. I'm running an even ratio (48-18).

Would this probably be the case or something worse?

Cheers!

check the pedals too.

yeah and v good chance you got a stiff link in the chain. easy to sort. good advice from shins too. MOH

I had this last week while working on a conversion, it was just a stiff link but it went away after slackening the chain tension. Try turning the cranks really slowly and wait for the click, see which link is about to go round the sprocket/chainring and mark it. Spin a few more times and repeat. If its the same place then its a stiff link.

Check - Pedals!

Thanks for the advice!

Will I have to remove the link completely if I find the stiff little bugger? ;)

You sure it's not your knees?

nope.. just get the chaintool out and have a play around with it... should be able to fix it :) clean and lube will also help

before you grab the chain tool and get stuck in an endless loop pushing the pin a bit too far each way never loosening the thing up. Just grab the chain either side of the stiff link and flex it back and forth a few times, dont be gentle. That will more than likely sort it out. Unless of course you can see that the pin is badly positioned.

good point!

Sweet.
Gonna give it a go this afternoon, have my chain tool on hand just in case.

Ta!
