The resistance on my ancient rollers allows me to put it in 53X12 (I don't ride with an 11) and get well into zone 3 at about 70 rpm. I think the Sportcrafter set has even more resistance. Standing is similar to standing on the flat, similar issues with getting a nice pedal turnover at low cadence. I have straight 4" ABS drums.
