Naive questions.
1) When measuring the size of the variator rollers with a digital caliper should I round up the values to the next whole number to order the correct size? Example: 19.87mm -> 20 and 14.92 -> 15.
2) Should replacement rollers be identical size, or can I install slightly smaller size (to get less weight)?
3) I'm having trouble locating a good US supplier that can deliver rollers within 2-3 days. Suggestions?
