AFTER 10-20 HOURS OF CYCLING 1. squeeze front brakes and rock the bike forward and back, and listen. Does everything feel and sound solid? 2. Lift the front wheel from the ground and swing from side to side. Any roughness or un-smoothness in the steering? 3. Check each pedal. Anything loose? 4. Check the brake pads. Any signs of wear? Do they hit the wheel rim squarely? 5. Check cables for rust, fraying and kinks. 6. Squeeze each pair of spokes to see if they all feel about the same.
