After talking with the guy from avid and discussing with SkiBreeze, I am going to get the "bolt on" track with a anti stab kit just in case. If it turns out I have ratcheting or too little clearance I will order the 2.86 7 tooth drivers from avid. I cant see any reason to go to the 3.0 pitch if the 7 tooth 2.86 drivers are available. I am betting I will be just fine with the bolt on track.
I just hope I didnt misunderstand him when he said I could get a smaller driver in the stock pitch.
Does this look right? https://www.avid-products.com/store/ProdDet.cfm?ProdID=103
I don't think that you can get a 7 tooth 2.86 driver.
