All the scientific evidence we've seen indicates that the answer to this important question is no. Cycling is one of the best activities for fun, good health and fitness and there's no reason to worry about sitting on a bike seat.
But, if you're uncomfortable in any way when sitting on yours, and you're pretty sure that your saddle is adjusted correctly (improper adjustment is one of the most common causes of discomfort), we recommend considering a new seat.
Why? Because, there have been impressive advances in seat technology in the last couple of years and we have many new models specifically designed to eliminate pressure on sensitive body parts, which is probably what's annoying you. These cool seats employ shapes, shock absorption and padding specifically selected to prevent pain and increase comfort and many happy customers swear by them.
If you're new to cycling and it hurts to sit on your seat at first, it's not likely to cause any serious damage. Keep your rides short and see if the discomfort subsides after a few days. If the pain continues or worsens, call or come visit us right away for suggestions. One of the new breed of saddles, or some fit adjustments, can make all the difference and make riding enjoyable again.
