    3 by 9 to 2 by 9

    Hi. I never use my large chain ring so I want to remove it. I removed it and realized the second ring wobbles because the bolt is expecting for the 3rd ring to be still exist. Is there a way to take a 3 by 9 crankset and convert it into a 2 by 9? Basically, is there some sort of spacer you can purchase for the bolts to get the 2nd ring and granny ring to be tight against each other or do I have to go and buy a 2 by 10 if I only want a 2 ring set up?

    Thanks, mtbfan2

    You need single speed chaining bolts (shorter) or run a bash guard in the third ring position.

    Bashguard is the way to go. Not only will it protect but also help keep the chain in place. Also.. don't for get to set the limiter screw on your front derailleur..
    Its a JEEP thing. I have 4 and still don't understand..
