Pelvic Angle

Summary

Pelvic Angle measures how much the pelvis is tilted upwards.

Details

Each cyclist has a different neutral pelvic alignment. Finding a natural pelvis position engages the core muscles and reduces lumbar spine strain.

Coaches have observed that riders with an upright Pelvic Angle have a higher chance of back injury. If the pelvis is tilted too far back, lumbar strain can occur, and if the pelvis is tilted too far forward, maximum Leg Angular Range cannot be achieved. Also, posterior rotation of the pelvis reduces power generation capability.

Score

The front-to-back (z-axis) angle of the hip. Straight up is 90 degrees, while 0 degrees is parallel to the ground.

• The Pelvic Angle is information on posture, and there is no particular definition of good or bad

• However, if the posture is too shallow or too deep, the pelvis may be tilted forward due to lack of hip flexibility or lack of stability in the trunk or lack of flexibility in the spine, so it should be judged comprehensively.

• This threshold assumes bracket position in sitting, not when holding a drop bar or flat bar or while standing.

Value Range	Level	Visual Reference
70°+	-	Very shallow forward leaning posture
65 - 70°	-	Shallow forward leaning posture
60 - 65°	-	Normal
55 - 60°	-	Deep forward leaning posture
- 55°	-	Very deep forward leaning posture

Attention

*Uphill and downhill (gradient section)
The Pelvic Angle value indicates the angle in relation to the direction of gravity (not the angle to the bike), so care must be taken when riding on a gradient section such as uphill or downhill, or when validating data in the velodrome.
