Today's Cycling Tip

Saddle Position Spells Satisfaction (Or Suffering) - The angle and position of your bike's saddle directly contributes to your comfort. Sure, saddle height is important. Yet saddle tilt and the saddle's fore/aft positioning also relate to how your hands, neck and back feel when you ride. For instance, if the nose of the saddle tilts too low, gravity forces your torso to slide forward as you ride, putting extra pressure on your palms. Tilted too far back (the saddle nose is too high) pressure on sensitive soft tissue can lead to serious complications and pain. Sliding the saddle too far forward or too far back affects your spine, neck, shoulders, arms and hands. It takes experience (and sometimes a few adjustments) to find the optimum saddle position for comfort and pedaling efficiency. If you're experiencing any saddle discomfort, please contact us to discuss possible solutions.
