Been there... Done that... I know that getting a single speed crank would be easy but that's boring... I chose this crank because of its style... The chain tensioner has nothing to do with a straight line.. It just accounts for the vertical dropouts... The straight lines comes from spacing out the rear cog (it's all explained in the original post) Unless you are referring to a special chain tensioner that also adjusts chain line... But that's a little too close to a derailleur...
I have already built numerous single speed bikes but none using an aluminum frame with vertical drops...
If you read the original post you will see that I have asked four specific questions,
Thanks =)
