    Chain slack.

    Hey guys,

    Just about done switching from 3x9 to a 1x9 setup. The last step is to take out (possibly) some link from the chain. That's where I need your guys's help. I took off my highest and lowest chainring (22 and 42) and kept my middle 32 ring. Since I have took off the big ring, I assume I would be able to take a few links out of the chain. Here are pics of my bike in the highest and lowest gear. If you guys could suggest how many link to take out, or have a pic of a bike in high and low gear that has optimal chain slack. Then i could just look at the angle of the RD. Also, I plan in June to add the small ring back on for a trip up to Oregon. If i take a few links out of the chain, and later add the small ring back, it would run fine right? Since it is a smaller ring? Or would it not, like when I am in the small ring and the highest (smallest) rear cog?

    Thanks guys,
    Matt

    set it in the largest ring in the back.. and pull out all the slack so that the chain is nice and tite.. not too tite.. you still want some play but not too much

    As is so often the case, Sheldon's advice is the best/simplest I've read on the matter:

    http://sheldonbrown.com/derailer-adjustment.html#chain

    "The best technique for setting chain length is to thread the chain onto the large/large combination, without running it through the rear derailer. Mesh the two ends on to the large chainwheel so that they could be connected (outer link meets inner link), then make the chain one complete link (one inch) longer than that. In almost all cases, this will give the optimum length."
