Hi Everyone! I am a TOTAL biking newbie...just got my first bike in over 10 years a couple of weeks ago. Long story short, I fell in love with spinning at the gym, decided to try some sprint triathalons, and my super wonderful boyfriend bought me my new Trek 2.3 WSD Anyhoo, I have been taking it out for 20-30 mile rides a few times a week since I got it, and I'm getting used to it (even had my first clipless pedal no-speed fall!) except....I am a bit confused about braking. Should I be using my front brake primarily? What about on hills? Hills scare me quite a bit, but I'm often afraid to brake hard, 'cuz I'm afraid of skidding or flying over the handlebars. Any advice you can give me would be TOTALLY appreciated. I love, love, love riding my bike and I want to get better and more comfortable. Thanks all!!!
