Dyreex Black Edge 1.25mm String Test January 8, 2016 06:51

Here are the test results from engineer Gabriele Medri, of pro-t-one tech labs, on the Dyreex BLACK EDGE 1.25mm string:
A dynamic, responsive, and highly competitive string. An absolutely suitable choice for competitive players of all types, both in fullbed and hybrid setups.
The Dyreex BLACK EDGE 125 is a string with a strong competitive nature, as evidenced by the considerable static stiffness of the filament, which shows a linear and rather constant trend. Power levels are quite high, although, like all strings of this type, it is available at high speeds, meaning for trained and fast arms. Stability is decent, and it shows substantial hold after an initial natural and physiological settling that will occur in the first 2 hours of play, with a progressive stiffening of the string. In this case, a slight 5% pre-stretch action with a tension reduction of 1.5-2kg compared to standard reference tensions could be recommended.
The maximum resilience tension range is between 16-18-20kg, however, at low tensions capable of maximizing the dynamic performance of the string, whose durability is more than good, settling around 9 hours (very respectable for a monofilament). Static tension retention is absolutely referential, at the bare minimum. Dynamic stiffness falls within the average values for competitive polyesters.

A good string, according to the rankings on stringforum.net, at a very attractive price of €6.90 for the reel and €68.00 for the coil, available in 1.25mm and 1.30mm gauges.
