frequently asked questions

Choosing the right set starts with your child’s height and wrist-to-floor measurement. These two factors allow us to match them with a set engineered for their size, swing speed, and stage of development. The result is better contact, improved consistency, and a more natural swing from the very beginning.

Most junior golfers will need to upgrade every 6 to 12 months, depending on how quickly they grow. Rather than replacing the full set each time, our system allows you to upgrade only what’s needed, keeping performance consistent while adapting to their changing size.


Yes. The upgrade process is designed to be simple and straightforward, with components that can be changed at home in minutes. No specialist tools or fitting appointments are required, making it easy to keep your child’s clubs perfectly fitted as they grow.


Not at all. Every upgrade is engineered to maintain the same performance characteristics and feel your child is used to. The transition is seamless, allowing them to continue developing without disruption or adjustment.


Yes. These are not scaled-down adult clubs. Every element is built specifically for junior players, from shaft flex and weight to club head design. This ensures the clubs work with their swing, rather than against it, helping them develop proper technique from the start.


Absolutely. The system is designed to grow with your golfer. You can start with the set that matches their current size and ability, then progress through each stage using targeted upgrades rather than replacing everything.


Yes. The sets are designed to support golfers at every stage, from first swings through to more advanced play. Each stage introduces the right level of performance, forgiveness, and control to match their development, building confidence as they improve.
