Here’s a great list of 101 tips from Bicycling Magazine.
Some are obvious. Some I learned from my friends. Some are ingenious. Some ideas I hate.
The first ten are here. Then check out the rest.
To avoid muscle soreness and fatigue, don’t hunch your shoulders. Tilt your head every few minutes to stave off tight neck muscles. Better yet: Stop to admire the scenery.
By sliding rearward or forward on the saddle, you can emphasize different muscle groups. This is useful on a long climb as a way to give various muscles a rest while others take over the work. Moving forward accentuates the quadriceps, while moving back emphasizes the hamstrings and glutes.
If you’re not comfortable taking both hands off the bar, after pulling an arm warmer down with the opposite hand, use your teeth to pull the bundled fabric the rest of the way over your wrist and off.
NO. 4 Don’t move your upper body too much. Let your back serve as a fulcrum, with your bike swaying from side to side beneath it.
NO. 5 Keep your shoulders behind the front wheel axle. Too much weight forward makes the bike hard to handle and could cause the rear wheel to skip up into the air.
NO. 6 Pull on the bar with a rowing motion to counter the power of your legs. This helps transfer your energy to the pedals rather than into wasted movement.
If you don’t have a chance to slow for an obstacle such as railroad tracks or a pothole, quickly pull upward on the handlebar to lift your front wheel. You may still damage the rear wheel, or it might suffer a pinch flat, but you’ll prevent an impact on the front that could cause a crash.
Beware of creeping forward on the saddle and hunching your back when you’re tired. Shift to a higher gear and stand to pedal periodically to prevent stiffness in your hips and back.
Relax your grip. On smooth, traffic-free pavement, practice draping your hands over the handlebar. This not only will help alleviate muscle tension, but also will reduce the amount of road vibration transmitted to your body.
Periodically change hand position. Grasp the drops for descents or high-speed riding and the brake-lever hoods for relaxed cruising. On long climbs, hold the top of the bar to sit upright and open your chest for easier breathing. When standing, grasp the hoods lightly and gently rock the bike from side to side in sync with your pedal strokes. But always keep each thumb and a finger closed around the hood or bar to prevent yourself from losing control if you hit an unexpected bump.
