Sputnik Chainstay Fixture Question

Hey Folks,

I have an email out to Jeff at Sputnik but I’m hoping to get an answer faster.

Sputnik’s Chainstay fixture has two scales on it.

  • One that corresponds to the “dummy tire”
  • One that corresponds to the horizontal CS length.

What does does the scale for the CS length start at?

Mine starts at about 228mm.

  • if I measure from the front face of the fixture that number should be 163.6mm
  • if I measure from the BB center (25.4mm in front of the fixture) it should be 189mm

The reason why I’m asking:

It’s been about 5 years since I last used this fixture but I seem to remember that there was a mistake with the scale and I needed to do some adjustments to my measurement to make things work.

I know the scale on the Sputnik SS fixture is just for reference but I believe the CS actually corresponds to real numbers.

Thanks!
