This is probably a dumb question but I’m open to advice.

Should or will I care about “miles” on the rollers? I have a power meter that also reports cadence, so I don’t have a speed and cadence sensor. Speed and distance aren’t that important to me, I’ve always been happy to leave that to GPS. It’s time and power that will matter to me when I’m using them. The only use I can think of for miles is maintenance, but I keep reading that rollers don’t wear your tire, and I don’t expect I’ll need to shift much with them. But if I’m going to want it, I might as well get the sensor ordered so it’ll be here by the time I pick a set.
