How to Build a Tennis String Lineup: EDGE and NEXUS Series as Examples

A strong tennis-string range is not simply a long list of model names. Each SKU should answer a clear user need. The EDGE and NEXUS families are useful examples for thinking about range architecture because they can be organised around profile, gauge and intended use rather than around marketing names alone.

Start with product roles

Before adding models, define the questions a buyer will ask: Which option is the balanced reference? Which one prioritises wear resistance? Which one is aimed at players who want a more distinctive shaped profile? Which gauge is easiest to recommend to a first-time customer?

Once these roles are written down, it becomes easier to decide whether two products are genuinely different or merely competing for the same position.

Keep the specification ladder easy to understand

Gauge is one of the clearest ways to create a logical progression. A range might include a thinner, middle and thicker option, but each step should have a reason. If two models have almost identical diameter, construction and target feel, consider whether both are necessary.

Use controlled sample testing

Retailers and OEM buyers should compare samples at the same tension and in the same racket. Record initial feel, control, string movement, visible surface wear and how the response changes after several sessions. The aim is not to find one universal “best” string; it is to understand where each model fits.

Make the catalogue help the customer decide

Product pages should show the specifications that matter: model, series, gauge, length, material and construction notes. A short recommendation such as “balanced reference gauge” or “durability-oriented option” can be more useful than a long list of vague claims. Clear differentiation reduces returns, improves sales conversations and makes future range expansion easier.
