Quick Help Please! Dura Ace Chainrings(8 posts)

Quick Help Please! Dura Ace Chainringsjzinckgra
Nov 7, 2002 8:25 PM
I am installing some new DA chain rings on my FSA cranks. Here's the problem: what is that little pin that sticks out on the inside of the 53 tooth ring? It's about ~1/2 inch long. It's hitting my chainstay when it goes around. Is it some sort of pick up pin for the chain? I notice it "catches" the chain on the way around when in the 39 tooth ring. I didn't have these on my Stonglite rings. Help please! Thanks.
Are you serious?JS

Okay, I'll bite. wait.....nope, you can't have done what your describing. If you have, now don't take this the wrong way, you probably shouldn't be working on your own bike. If this is a troll, you suck.

Hey man, not everyone knows everything about everything....catch my drift. I was in a rush an installed the rings backwards and since I wanted to ride tomorrow, I wanted to make sure I did it right. Thanks to most people, not including yourself, I fixed a minor problem. I believe the best way to learn how to do things is by learning from your own mistakes. Take a chill pill buddy....
In a year you'll look back on what you didJS

synopsis: the only stupid question is the one asked after a screw-up.
I see that you've had your questions answered on the Calfee sitegogene

Good. Don't let people get you down, just 'cause they think that they know more than you do.

All of the Shimano crank-sets I've looked at have the tooth count stampings facing right on the big ring and left on the inside or middle rings. I got an inside ring backwards once. It would shift OK but with the chain on the inside ring it was dragging on the big ring when on the right side of the cassette.
My wife's Campy triple has all tooth count stampings facing right.

Just to be clear (not been addressed in other posts), that little pin is to keep an "overshifted" chain from wedging between the crank arm and the chain ring. It should be facing away from the frame and match with the crank arm. I occasionally see these things at other locations on the crank, and am always amazed.
