The biggest size socket I have is 27mm. What is the size of the nut and is it reverse or normal threaded. If there is another technique to remove the nut I am open to suggestions. I know it has to be close to 32mm.

 

Its been a while since I messed with the sprocket but if I remember correctly I used a 1 1/4 in wrench. Not sure though just know that it is a pain in the a$$!

 

32mm or 1 1/4" socket will work. My 1 1/4" actually fits better than the 32mm that I bought.

 

Yep, 32mm or 1 1/4" and the the threads are not reveresed.

 

Use the 1-1/4" socket with an air impact. If you try to do it manually, the bike will roll as you try to loosen the nut. You'll love the 12t sprocket compared to the stock one.

 

Thanks for the input guys! I took a 1 1/4 socket 6 inch extension and a 20 inch breaker bar and it broke loose. Poped in the new sprocket and tightened the chain. Works great, but I am going to have to cut out a link or get another chain before the summer is over. I am definitly predicting that I will need a new chain soon.
