This problem is making me dizzy:P
Ok, so I am upgrading my Raleigh 3 speed to a cotterless* crank.
So here is my problem.
I have now a shimano UN72 BB 70X115. I also have a dura ace fc 1702 crank (takes a 113mm) with a single 48t chainring. My bike fram takes a 71mm BB, but seeing that it is a Raleigh 3 speed I have the Phil Wood BB retaining rings (26 tpi, thanks, Sheldon)that can be recessed into the frame 1mm... I figured I was close enough. I at first I was a little cocky, and figured I had this one in the bag, but as the parts are now in the mail I am growing unsure. I am over 1mm in the math, Is this going to effect me very much, or even going to work?
I hope I gave enough information to figure it out.
<3 and much love.
