Would I need to recalibrate the slope or similar if I buy one and convert it to 1x? Can I even run it as a 1X?
I recently contacted srm about a chainring change. Their answer:
Calibration is only required when changing chainring style/construction. Chainring construction causes slope to vary more than tooth count or variances among similar styles, so unless you’re changing to an ultralight ring or TT-style ring, I don’t think calibration is necessary. Crank arm length is also not a factor with the slope calibration method employed by SRM USA.
