Chain tension
« on: March 15, 2007, 11:31:30 PM »
I've noticed that the chain on my Raven AT is looking kind of slack.

How do I know what the proper tension should be? And adjust, am I better off removing a link from the chain or adjusting the BB?

See P9 of owners handbook  http://www.thorncycles.co.uk/thornpdf/ThornBikeOwnerManual2Web.pdf

PS I've been sufferring from 'chain tension' for the last 3 weeks caused by an irritating tick on the down pedal stroke!

Hi Andrew,

Wow I can't believe you have never needed to adjust the tension!  

Definitely best to adjust the BB first.  Only remove a link if the BB is in the max position and you still have a loose chain.  You probable know this but I say it anyway: It is MUCH better to have a chain that is slightly loose rather than a chain that is too tight.

I know! But I haven't put as many miles on the bike as I would have liked/expected. I suppose that's what happens when you have two babies and move half way round the world!
