Case Study 1 – Body Proportions

ISSUE: Finding a suitable frame geometry that takes account of particular variations in body proportions for the individual i.e. torso to lower body.  Some frame designs will suit a long torso and shorter leg combination whilst others will cater for the opposite.  It is important to know what will suit you.

THE RIDER:

Sports/Exercise History: Cycling within a proactive approach to fitness including working regularly with a trainer with free weights for strength

Riding Goals: Sportives, staying injury free

PRESENTING ISSUES:

• Relatively upright position on the bike
• Handling concerns particularly while descending
• A shallow drop between saddle height and bars
• Overall good strength and flexibility
• Hunching/tension around neck on the bike(caused by bike set up as off the bike measured showed no bodily cause for this)
• Slight localized tightness hip flexors and piriformis

ANALYSIS:

• Ian is relatively longer in the torso and arms
• His frame geometry suited someone with a longer leg length and shorter torso
• No flexibility/mobility issues that significantly limit position
•  Lumbar  flexion is slightly reduced associated with some tension in the hip flexors

CHANGES:

• A frame geometry with a steeper seat angle + greater reach to accommodate the length in his torso so suiting his body proportions
• Increased drop to aid handling and performance
• Specific hip flexor and piriformis stretches provided to improve fluidity of hip action and improved lower back biomechanics
• The longer position alleviated the tension around the neck by way of lengthening the spine from the lumbar area upwards

OUTCOME:

“It was great to find out what a good cycling position is supposed to feel like even if my current bike struggles to provide that!”
