The 27% range of crank lengths evaluated in this investigation is substantially larger than the 6% range (165–175 mm) typically available for adult bicycles, indicating that cyclists can change crank lengths without concern of changing their power production strategies. Furthermore, cyclists and triathletes wishing to adopt a more horizontal torso position to reduce aerodynamic drag could use shorter cranks to eliminate thigh to torso contact, which might compromise ventilation and/or power production. Cycling enthusiasts who have musculoskeletal impairments such as femoral-acetabular impingement or knee osteoarthritis might use shorter cranks to reduce maximum hip and knee flexion and thereby reduce the risk of symptomatic flare-ups triggered by larger joint angular excursions. Similarly, in rehabilitation settings...
