The saddle height is crucial and can be roughly checked using the heel-to-pedal method.
  1. Stand beside your bike and adjust the saddle height to approximately your hip bone level.
  2. Sit on the bike and place your heel on the pedal when it is at the bottom dead center (6 o'clock).
  3. If your leg is fully straight, the saddle height is a good starting point (approximately 70% correct).
  4. If your knee is still bent, raise the saddle.
  5. If your heel loses contact with the pedal or your hip rocks, the saddle is too high, lower down the saddle.
  6. Use your forefoot to pedal.
This method provides a safe position to prevent basic knee pressure. However, achieving optimal power transfer and efficiency requires dynamic measurement of knee extension angle (usually 135-145 degrees) under load, which can be precisely set using our 3D Motion Capture System.
(Diagnosis & Variety): Neck pain is often complex and rarely caused by one factor. Key factors include:
  1. Poor Posture/Rounded Back: A severely rounded upper back (kyphosis) forces the neck into an extreme angle to look forward.
  2. Overly Aggressive Setup: Too large a saddle-to-bar drop.
  3. Visual Obstruction: Eyewear or heavy helmets can force the rider to crane their neck higher for clear vision.
  4. Muscle Adaptation: Beginners' posterior neck muscles are unconditioned for the sustained static position.
Solution & CTA: While taking breaks and stretching helps, eliminating the root cause requires optimizing your Stack and Reach to ensure a neutral spine posture. A Bike Fitting analyzes your spinal flexibility to set the safest bar height for long-term riding.
1. Incorrect saddle height
2. Crank arms too long
3. Excessive use of the quadriceps (quad dominance).
1. Cleat angle is incorrect relative to your natural foot rotation
2. Lack of proper arch support (foot instability).
1. Saddle is too high
2. Hamstrings are overly tight.
Lower back pain is typically a failure of the core to stabilize the spine, amplified by the bike setup:
  1. Incorrect Saddle Angle: Leading to excessive pelvic rotation and increased lumbar pressure.
  2. Reach is too long (Aggressive): Forcing the rider into a stretched, unsupported, and often rounded-back posture,
  3. Reach is too short: Forcing round back.
  4. Overly Aggressive Drop: Large saddle-to-handlebar drop.
Hip pain often stems from restricted range of motion or improper muscle firing:
  1. Crank Arms Too Long: Creating a hip angle that is too tight at the top of the pedal stroke.
  2. Saddle Too Low: Leading to excessive hip flexion.
  3. Improper Muscular Firing: Relying too much on the hip flexors ("pulling up" on the pedals)
Pain or numbness here is a direct result of excessive pressure on the soft tissue, usually due to the contact point:
  1. Incorrect Saddle Shape/Hardness: Not matching your sit bone width or overall riding style.
  2. Weight Distribution Too Far Back: Increasing pressure on the saddle.
  3. "Casual" Riding Style: Failing to effectively transfer weight to the pedals, leaving too much load on the saddle.
