I shifted down until I started to bounce, then shifted back up one gear and spun at 90. I did one this morning and achieved the 90 that I wanted for 15 minutes. I would like to eventually see 100 or better so now do I increase time at 90 first or do I try and stay with the 15 minutes and get to 100 before I increase the time or speed?
