    Cog removal tool? (x-post)

    I tried aksing this on the tool board but it seems to be dropping and I'd like to switch out cogs soon so...

    Does anyone know what tool I need to change the cog on my Redline monocog 29er? It is a cassette style cog/hub except the lock ring is different than what is on my geared bike. I looked at the parktool site but can't figure out what tool to get. Any help is appreciated.

    Try this little guy: http://www.parktool.com/products/det...5&item=HCW%2D5

    It's listed as a BB tool, but it's what you need for lockrings.
    You COULD do it on a geared bike, but I wouldn't reccomend it!

    Derailleurs are for failures!

    Does the lock ring have 6 notches? The Pedro's 6 notch wrench fit the lock ring on my wife's WTB SS hub perfectly.

    I used a hammer and flat head screwdriver. Tapped it a few times and loose enough to turn. Same for putting it on.. Spin it on then tap it a few times.

    I've got that tool, not that great for the Monocog's lockring, you can only use the one-toothed side and it is hard to get any bite without slipping off.

    I use one more like this:

    This is the updated version of what I have, which might work better because I had to take the dremel to it and modifiy it a little to get it to slip onto the lock ring.

    You'll most likely have to use add a cassette spacer if you're using thinner stamped cogs or the free hub might interfere with this tool getting to the lockring.

    Just keep spinning. Just keep running. Just keep paddling.
    Just keep moving forward.

    This to bite on to the lockring, and one of these to keep the cog from spinning. If you line them up you can use one hand to break the lockring free and the other hand to steady the wheel (or place the wheel between your knees). Fairly simple operation, it's a bit expensive, but worth it if you change out cogs often.
