WTF guys, can someone help me please!

Hello,

I am having problems with the drivetrain on my Spiuk. I somehow lost 4-5 teeth off my casette on my first ride, which is really annoying, now when I looked at it I think I have a different problem! As you can see the derailleur is all pushed foward and I have never seen this before, the same thing happens but it goes backwards in other gears, I have never seen any bike like this. The other thing is, The chain comes off all the time on the largest cog on the crank AND it takes ages to change gear when its on it's stand , how can I fix this? Sorry for the seemingly stupid question but I am very new to this 'game'
quick responses would be great as I am going to get new parts,

Thanks very much


Jack

In the first and third pictures it looks like you are crosschained and running big / big. For starters, don't do that.

Your next problem, it sounds like you need to do two things. You need to tighten up your front cable a little bit and you need to adjust your limit screws. The limit screw being out of adjustment is what is allowing your chain to fall off.

If the bike is new just take it in for a quick adjustment, it should be free. While you are there show them the problem with the cassette, that should be warranteed.

"Fragged" is a term that comes from video game play, I believe. If your character gets killed, you've essentially been 'fragged'. Not sure what the origins are or if it really originated from video games but it's the context I've heard it the most.

To me fragged is when you take a small piece off of it and then let it grow up into a new one. At least that is what I did with corals in my saltwater reef tank. Made me all kinds of money. If I could frag bike parts I would be a rich man!!!

Check your chain length, there are various rules of thumb and formulae at parktools.com repair page.
The sprocket teeth are profilled and ramped for easy deraillment. Dont confuse this with a broken tooth.

Fragged is short for fragmented, i.e. - destroyed, toast

It's a term that came out of the Viet Nam war...when grunts tossed grenades into the tents of unpopular officers and NCO's and "fragged" them

Really, that's its job. It is trying to keep tension on the cable so the chain doesn't fall off. In the pics you posted, you can see in the middle one that the "arm" of the D is "coiled" but creating tension. As you go to physically larger gears, the arm extends but keeps the chain in tension.

As for if it happens on my bikes, very rarely as I try not to go into the "big-big" ring and gear at all. This is why you have additional front rings. If you went to your middle ring, you'd find a gear that would work in whatever situation you thought you needed the big-big combo.

No, I don't think your derailleur is broken.

I see absolutely nothing wrong here. When you are in your largest cog in the rear and largest chain ring in front your RD should look just like in the pictures. As for the chain falling off when cross chaining I wouldn't adjust anything, that is also normal, just stop cross chaining and you will be fine. Same goes for the sluggish shifting in the rear when cross chaining. When cross chaining, your gears they will obviously not work perfectly, which is good because it teaches people to find a different gear instead of rapidly wearing out their drive train.

"Frag" came from the slang for fragmentation grenades. The term for growing coral with small pieces probably derived from fragmentation as well.
