Plastic disc between cassette and wheel

[Mad Doug Biker]

I have always vaguely wondered what they are for, but have never really followed it up.
I am no Pieplate snob either and wouldn't lose any sleep over them.

 

[I like Skol]

I have always advocated leaving them in place if they are not broken or rattling. As has already been said, a small fall, or getting a twig or other debris caught in the cassette can send the chain off the back and into the spokes where it does a good impression of a chainsaw, chewing away at your spokes until you stop. It's up to you! Follow fashion and vanity or be a bit less self conscious and stand out from the crowd with your practical common sense...... Oh wait, I see you already hacked it off

It's the first thing I used to do, get rid of the pie plate (dork disc). But now on my 4th bike, the SuperSix, still has it - haven't got round to taking it off yet and not particularly fussed either. It's kinda like a semi-aero-disc.

I replaced mine with a doily

Most people do not need one, but I bet this bloke wished he had.

Only because it was cracked and filthy...

To be honest - I think I might replace with a nice shiny new one - if I could ever find one online to buy....

I picked up a bit of wire (that thick stuff from car wheel trims) riding home one night in the dark. It jammed the deraileur and guided it into the spokes. Result, broken deraileur hanger, broken deraileur, wrecked rear wheel, damaged chain. Would a dork disk have prevented at least some of this? Probably.

Also refered to as a dork disc, I believe...

A good chance it might of, but you will never know for sure.

If you do bin it make sure your rear derailleur stops are set up correctly and take great care never to bang the derailleur on anything(which you should do anyway).The pie plate could save you a lot of expense one day.

So could nappies for that one day you get the trots.

Rather go without them day-to-day though.

There will come a time when you revise this flippant nappy decision.

Your best chance when things go pear-shaped is single-speed or fixed, it's just a lot more robust.

So if I did want to put a nice shiny new clear plastic 'dork plate' back on my bike - where the hell do I buy one???

Can't find any online...

Google 'Spoke protector'.

That's a pants analogy.
