One day of going to and coming from work:
• 4th feels most “natural” most of the time (speed+effort), especially going to work which is a lot less hilly than coming from work.
• 3rd isn’t enough to go up steep hills/bridges, but is well enough for those >1/2-mile stretches of slight, steady inclines coming from work if I can temper my patience going comparatively slow.
• 5th, even on a few blocks of windless flat road, HURTS. But I’m going comparatively quick. Probably nowhere near as quick as even a hybrid, but much faster than I’m used to when mine was single-speed. Something tells me I’m going to have to earn 5th.
• It’s going to take quite some time to learn when I should switch to 1st or 2nd for uphill.
