Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Nubie Question?

I was reading another post and someone told another poster to remove his "DD" post haste. After looking at my new Cannondale Caad9, I think the "DD" is the clear plastic component between my cassette and the frame. One, am I correct? Two, if so, what function does this "DD" perform? Three, should I remove this and why?

Thanks, in advance, for any help.

Dave

Yes, the "DD" or dork disc is the clear platic thing. Remove it. ASAP.

It's a spoke protector. It's there so that you don't send the chain flying into the spokes when you shift into your largest cog. If your derailleur is properly adjusted, you shouldn't need it. I would remove it, I think it looks much better without it, and it's not necessary if your derailleur is adjusted.

DD stands for Dork Disc. It's purpose is to prevent the chain from destroying the spokes of the rear wheel in the event it should jump passed the low gear into the spokes. This can occur if the rear derailer limit is not set correctly. It is absolutely neccessary if you purchased your bike at a big box store like Wal-Mart, Target etc. If you purchased a bike from a reliable LBS with a good set-up mechanic it is excess baggage.
It is not uncommon for a "FRED" rider to keep the dork disc.

Everyone,

Thanks for the quick responses. I bought it from a LBS and have had no problems shifting for the first 100 miles. I think I'll take some wire cutters to it tomorrow morning. Also, thanks for teaching me some of the lingo. I need to search for all of the TLA's and other acronyms.

This will be a good learning experience for you! Like everyone said, it's so you can't overshift into the spokes and then cry to the LBS that your bike is destroyed. If you don't know how to do these things already, this is a perfect opportunity to learn how to remove a cassette and make sure that your dérailleur limits are set properly.

Wire cutters will work, but I'd rather remove the cassette and then remove the spoke protector like Dr. L'Ling suggested. It's never a bad idea to learn to do something new, especially regarding bike mechanics. If your LBS is anything like mine, they charge way too much for basic adjustments and other simple jobs and make buying the tools and learning how to do things yourself a much better deal. Nothing against my LBS though, I love riding with those guys and I don't mind running in to pick up a few gels or a spare tube or something, but the mechanics make an insane amount of money.

I doubt it. Factor in the rent, insurance, utilities, owner's pay etc .....

+1 to the rest of it. I do everything myself, except frame painting.

Maybe I should have said charge instead?
