I thought I spin okay but my avg cadence on some hillier rides is usually in the mid 60s (I typically maintain 80s and 90s on the flats). Flatter routes, mid 80s if I work on it. On the trainer, mid 90s for an hour or two. I used to be able to maintain 120 rpm for an hour or two on rollers but that's no longer the case.
