Tour Lock Pro 100 Gram Weight Obviously, there have been lots of advances in club technology in the past 25 years. One of the most recent is strategic weight placement, and studies show that when the proper weight is utilized in the grip, overall performance improves. Back-weighting a club has been around for a while now, and the grip itself is, in essence, a backweight, but it's never been easier than using the Tour Lock system. Tour Lock Pro technology has made back-weighting easier and more efficient by allowing players to easily adjust the feel and performance of any club by adding the optimal weight to each club in their bags. Choose your weight, install and hit the course!
