Why take sit bone measurements?
During normal sitting, the sit bones are designed to support the body weight and can absorb high pressure; this should also be the case when cycling. Thanks to the SQlab saddle width concept, the main load of the body weight is placed on the sit bones when cycling. The distance between the sit bones varies from person to person, so to ensure that the sit bones have sufficient contact surface, this distance must be measured to determine the appropriate saddle width.
