the one i have is a 1" (20mm)

 

Its actually a set of DNA wheels Im looking at, but DNA is out 66 tooth pulleys except for one style. Lots of 70 and 65 tooth just no 66. I did manage to find a pulley on e-bay 66 tooth, 1" wide in my style but DNA said it needs a 1-1/8" wide so now Im torn.

 

Hmmm, part of me wants to say they are full of crap and u should be able to get the 1" wide one on ebay.

but I don't trust DNA... and ur soon gonna learn that also. I had a hell of a time getting my rotors and sprocket from them. They sent me the wrong one also.. a 70th. We went round and round about this and they told me they didn't have any 66th sprockets. I said give me my money back and they said oh... wait. we do have a 66th.....

The other part of me wants to say knowing them now they probably need the 1 1/8th sprocket for some offset reason used with their wheels. Guess I don't know what to tell you.

Did they tell you why you need a 1 1/8? If it's just because they simply think the belt is that wide tell them they are wrong and they have been making it wrong all this time.

 

i just picked up some PM wheels and rotors and the book said 66 tooth for the 07 train

 

Another thing Jtmurph.... just in case...

I put the DNA 66th sprocket on my stock Heritage wheels. To do that I had to get a .200mm spacer to go behind the sprocket to align the sprocket correctly with the primary. Make sure you check that. I don't know what you will need for DNA's wheels but I do know for the stock wheels I had to use that spacer.

I doubt DNA can even tell you. You might have to figure that out for yourself or have someone do it for you. I had a local wrench tell me what spacer I needed and then got it myself and put the whole thing together. Think it cost me 50 dollars to have him measure it for me.

Just fyi.
