I’ve used the Simpson strap that David shows for several years now…in addition to strengthening the neck and shoulders in my regular workout routine. Both have made a major impact to reduce the “neck noodle effect.” I have clips attached to both sides of my Bell GP2 helmet; two straps. Only ocassionally have I used both straps at the same time. The straps do limit the ability to turn my head to look beside me. But I work around that limitation. The straps make a major difference in long, high Gs turns. I only road race.
