    Chain tension

    I put on my new chain, and its kind of saggy. Should I take out a few links? just wanted to ask before I messed anything up.

    I was gonna ask the same questions, but after searching the forums, apparently it seems ok to do so.

    My chain on my bruiser was insanely short. It would break somewhere, so I'd take that link out and put it back together. I did that probably near a dozen times. Near the end I couldn't shift into the larger gear combos(from the chain being so short), but I had very little chainslap!

    Count the links on the old chain, or just get both side by side to compare, then remove links

    It worked and wasn't saggy, that's good enough for me.

    It's most likely just in your head. I've never heard of one chain being easier / harder to pedal than another. Just make sure it's lubed and the right length.
    I may be fat but I'm slow enough to make up for it.

    I've never liked the method that Sheldon Brown suggests. It's not a bad way, just not fool proof. I take a somewhat more detailed approach.

    1. I loop the chain through the derailleur and put it in the BIG-BIG combo. I pull the read derailleur forward so the lower jockey pulley is barely in front of the upper jockey pulley. Since this is the worst case senario, you want to make sure you are not overstressing the rear derailleur. I mark the intersection point with a marker.

    ****an old bent spoke in the shape of a long flat "U" will hold both ends of the chain together without having to cut or connect them permanently.

    2. I then put the chain into the SMALL-SMALL combo. I check where I marked the chain previously. If the rear derailleur's upper jockey pulley is dragging on the chain, the chain is too long. Mark off one link (one inside plate & one outside is ONE link).

    3. Go back into the BIG-BIG combo and check to make sure the new length doesn't over stress the rear derailleur in this combo. If it does, leave the extra link IN!

    It's always better to have the chain too long and have the rear derailleur drag in the small-small combo than too short and blow up if you ever accidently shift into the BIG-BIG with too short a chain.

    The reasoning? You should NEVER be in the small-small gear comination anyways!

    One last thing!!!! If you have a full suspension bike, do these measurements with someone sitting on the bike loading the suspension. Some full suspension designs affect the effective length of the chainstay as they cycle through the suspension travel. A correct chainlength in the stand can be too short when you're riding!

    hmm, i realise one thing new with my Deore LX chain (shortened to 8 speed), it feels smoother, everything from shifting to power transfer feels different. Very postive reply, lets hope ill win the school close competition. Too bad I dont have any sponsors and my Giant Anthem 2 hasnt arrive yet.

    What do you mean "shortened to 8 speed". The difference in an 8 speed and 9 speed chain isn't length, it's width.

    Your dealer may have very well shortened your chain, most chains need shortened. However, the length of the chain depends on what cassette, chainrings, and frame you have not by whether it is eight or nine speed.
