I struggled to find the words to put this into a Google search term that would throw up what I’m looking for...
On a fixed gear bike, how much further along the dropout will the rear axle move if I up the number of teeth on the sprocket by one tooth (chain length, tyre and everything else remaining the same)? I’m wondering how much closer to the seat tube my tyre will get if I get a bigger sprocket but keep the same number of links in my chain.
Thank you in advance to any nerd geniuses in the house : )
