    Your logic is right, but you have the adjustment backwards. He wants to add tension. He is going over the smallest cog and not into the easiest. The cable has too much slack and won't pull the RD into the biggest cog.

    Re: Official non-motorized motorcycle thread.

    To help answer your group set question - I need to know a couple things...if everything is "stock" as bought, the easiest way is if you can you send me the OEM spec sheet or the make/model/year?

    The info I need is:
    1) Hydraulic or Cable brakes (if hydraulic there are a few more questions)
    2) What spec bottom bracket
    3) Are wheels 8/9/10 speed or 10/11 speed compatible

    I found the easiest way to upgrade a drivetrain was to buy a new bike

    Definitely a symptom of needing simple adjustment. It can also be due to a bend, worn parts, or something more serious. But most of the time it's just a simple adjustment. The cable stretches over time, and sometimes slips a little at the clamping bolt.

    Click the RD shifter down to the smallest cog. Undo the cable fixing bolt, and reseat it. Set the lower limit screw so that it touches, then back it out a tad. Walk the shifter up a gear at a time while pedaling. It should progress up the cogs smooth. If you hit sudden, strong resistance nearing the largest cog, check that the upper limit screw isn't set in too far. You might need to fine tune the barrel adjuster a tad to get it even throughout the range of gears, but it should be really close to right from there. When testing, be very careful as you get to the largest cog, and be ready to stop pedaling the split second the chain jumps in to the wheel.
