    Trouble shifting into smallest cog on 10 speed setup

    I replaced the cable set for a friend's Scott Addict last night, and I had trouble tuning it properly. It doesn't want to go into the smallest cog. It will, sometimes, and sometimes just 'thinks' about it and doesn't.

    The limit screw is backed all the way off. The derailleur can't come out anymore. The hanger isn't bent. The derailleur isn't bent.

    It seems like I just need a little more separation between the cassette and the derailleur. I see three ways to accomplish this:

    1) Add a small washer on the drive side wheel shaft.
    2) Replace the Mavic (thick) cassette spacer with one or more 'regular' spacers, thus moving the cassette in slightly more. This assumes the locknut would still fit on right.
    3) Add a thin washer between the derailleur and the frame.

    What do you guys think the best solution would be? I'd estimate I need to move it 1mm to 1.5mm. Also, what do you think is wrong with this thing in the first place?

    Did it work properly before the cable was replaced? I had a similar problem and it turned out to be the cable clamp under the screw was turned 90 degrees from where it should have been. Look at the tech doc attached in the middle where it says make sure the cable is securely in the groove. I had it so the cable went under the tab like the picture on the right and it hit the derailleur hanger when I shifted into the small cog.

    Before you start changing parts on that hub, suggest you simply disconnect the cable from the rear derailleur and spin the crank. Thats a top-normal derailleur and it should automatically seek top gear with no tension on the shifter cable.

    If thats what it does then its working perfectly and your cabling is the issue.

    Thanks guys... you figured it out. I had the 'tooth' on the washer on the wrong side, and it was getting in the way.
