If you put the heel of your foot on the pedal and rotate it to the furthest point away from you, you should be just about locked out. When you then put the ball of your foot on the pedal like you normally ride, you will be just shy of full extension which should be a good ball park. You want the saddle as high as it will go without causing rocking in your hips or over extension in your legs. On Monday, December 12, 2022 at 10:06:58 AM UTC-8 cjus...@gmail.com wrote:
