So loosening your hams made your crank longer which gave you a longer pedal stroke?
No, riding 130 miles a week and 60 mile road ride on Sundays all winter gave me a longer stroke.
That plus working with my MMA ELITE trainer/fighter buddy getting stretched weekly and my current girlfriend was a gymnast, she fills in stretches for the trainer.
