Coach Fred Matheny Replies: The lower stem might be the culprit, or you may … [Read more...] about Can a Low Stem Cause Knee Pain?
By Coach Fred Matheny John Cobb was Lance Armstrong's aerodynamics consultant for his first five Tour de France victories. [Aerodynamics, of course, have nothing to do with PEDs, so Cobb's advice holds true no matter what one's opinion of Armstrong might be.] Cobb was known to draw artful pictures on an easel to illustrate his points. Here are nine you can use. … [Read more...] about 9 Aerodynamic Cycling Tips For Increased Speed

Coach Fred Matheny Replies: In a rainy ride or race, the issue isn't speed so much as traction. Rain won't affect speed by adding rolling resistance unless there are … [Read more...] about What Effect Does Rain Have on Speed?

If going uphill on various grades, what tailwind speed would compensate for the vertical gain? -- Dusty C. Coach Fred Matheny … [Read more...] about How Does Wind Speed Affect Gradient?
