Hey Tina,
Sorry for the long wait on the response... but I did put the sprockets on my bike and I love them.
I think I see the problem you ran into with the 13 tooth sprocket, but I fixed it with a little dremel work.
The sprocket and the locking ring weren't a perfect fit, but they were close enough that I simply dremeled out the holes in the locking ring slightly. That took care of the problem.
My 22" rears are on backorder, but I wanted to try the new gearing with the 20's anyway. The new geaing rocks for trail riding! My top speed dropped from 71 to 64mph (according to my gps), but I found that I was almost never at WOT in 5th gear, so I'm not missing much. I may need to go to a 40 tooth in the rear when my 22" rear tires come in... I don't know if I will be happy losing my new-found torque.
