I'm calculating the specs of a custom steel frame using Paragon sliding drops (flanged) and was using this calculator to find the optimal chainstay length using 32x18 or 34x18.
with a 32x18, it says the CS length is 16.725". Is this calculated under the ideal conditions where the chain is totally straight, or under real life operating scenario where there is some slack? If there's slack, my CS should be calculated around 16.85 or so i think.
The paragon slider window is 2", but given the 2 bolts that slide inside it, the axle only has 3/4" space to move. I was thinking centering the axle @ 16.75, then setting the sliders so that the shortest/longest CS is [16.5 ---> 17.25], or [16.4 --> 17.15].
This way, the axle at 16.75 will be in the front half of the slider position so that there's more overlap between the slider and drops.
Also, if i decide to move up to 34x18, i'd need a position of 16.45 or 16.975. Not sure if I can squeak this gearing into the [16.4 ---> 17.15 position] if i wanted to go short and run 16.45.
Any thoughts or recommendations on correcting my calculations?
