I've been averaging about 55km / 34miles a day on my indoor bike, including workouts and time trials. Due to periodic knee swelling, I had the steel forged 170mm cranks drilled at 150mm a few days ago, and raised the seat 2cm, which has been a big improvement. The constant dead spots are gone and my pedaling is quite a bit smoother. This is surprisingly especially noticeable when standing.
Since changing the cranks, I can use the same gears and rpms as previously to go the same paces as before, with no discernible difference in effort. Though the pedal speed around the circumference is lower, my feeling is that some of that previous pedal speed was wasted, due to the dead spots.
During a workout a few days ago, I experimented with different gears / rpms, and felt more efficient with a higher rpm but slightly below a 17/15 increase. There is much more experimenting yet to come, including a possible time trial by the end of the week, provided all goes well in the meantime.
