Yet another newbie question(8 posts)

Yet another newbie questionTylerman

For all the years I have been riding bikes, I never bothered to wonder what that little plastic disc is inside my spokes at the cassette. Does anyone know what it's called and what is it for? Is it intended to keep the freewheel clean or something?

I'm not sure what it is clled but its purpose is to keep the chain, should it come off on the inside of the casette, out of the spokes. If your Rear Der. is adjusted properly, it is not necessary.

a spoke protector.

Agreed, it's a throwback to times when many derailleur equipped bikes recieved virtually no preventative maintenance (as many inexpensive ones still do).

True, with a properly adjusted derailleur (limit screws) and cable... it's unnecessary.

We abide.

Remain In Light.

Another safety device for the casual rider.

If you drop your bike on the right side and the rear derailleur gets bent inward it could be shifted into the spokes causing a fairly nasty accident. The spoke protector may provide some protection from this.

Generally speaking an experienced rider does not need this.

It's there for several reasons. Firstly, it's there to prevent a chain from getting caught between the spokes and the cogs, for people who don't bother adjusting their derailleurs. It's also there to add weight, collect dust, and prevent adequate cleaning of the cogs. On many bikes, it's also there to denote the humble origin of a department store bike, especially if it appears in cojunction with rubber bar grips and chicken levers.

Gee, I wish the dork ring would still have been on my Rolf's after the LBS failed to put a spacer after the ring was removed. The cassette was loose on the mount, chain shifted over the top into the spokes and did a little chain saw action on 5 spokes.

It's proper name is "Spoke Protector." If you have ever shifted your chain into the spokes without one, even for only a second or two, you have buggered up the 8 right side, outside spokes. Once the spokes are deformed, they have a tendency to break one-at-a-time until all eight are replaced.

As some other posters have indicated, if you always keep your rear derailleur properly adjusted, you don't really need one.

Conversely, if you don't keep your RD properly adjusted (or if you are mechanically inept, like I am), you may one day appreciate having kept that little item on.
