Hi,
just bought a nice set of Phil hubs from Pistoffski yesterday (double fixed), and now I am wondering what 1/8" cog to put on to get a flawless chainline.
My chainset is 1/8" and 42mm at the front, so I want exactly that at the rear as well.
I measured the distance between mid-of-phil and shoulder to 36mm, so the cog needs to have a chainline (shoulder to mid-of-teeth) of 6mm.
So I looked up Sheldon's cog measurements at http://www.sheldonbrown.com/chainline.html and realised that there are not too many cogs with a 6mm chainline.
The phil cogs obviously are one of them, but as phil cogs are ridiculously expensive I am thinking of alternatives. EAI/Campa is 0.5 too wide, Surly not recommended by PW, so I am still thinking of Dura Ace because I do believe that the measurement for DA in that table is wrong if I remember correctly.
Could anyone with a DA 1/8" cog do me a favour and take callipers and measure their cog chainline (shoulder to mid-of-teeth)?
BTW, are all DA track cogs automatically model no. SS-7600 or are the NJS stamped ones a different model?
If you take a measure, please let me know if it's NJS stamped or not, would be very helpful
Thanks
