I want to change my front sproket on my scrambler from a 13 tooth to a 12 tooth for more woods power.


The chains are listed the same size in the rocky mountain catalogue and I have a nice o-ring chain. Do I need to get a new one? also the chains are listed as the same size for a 13-36 as 12-36 combo. Should I need a chanin breaker?

let me know what you guys think and if I should do this or not.

 

thers enough adjustment to run both. im running a 12/42 set up for all the low end i can get. can go to 11 front but too low for me, and the chain hits my swing arm then.
