New to biking and Clipless? Hate to say it but clipless does cause a few problems, but is the way to go. Glad you got the gearing sorted, but just a tip on that front. When going uphill and putting in pressure on the pedals- it may not be that easy to change gear. Can't explain it easily, but the chain is stretched into a straight line and no matter how much you try and change- it won't go. If you ease off the pedal pressure just a bit, the gears will change. This is more noticable on the front sprockets. Practice makes perfect, so get out on the bike and ride.
