Thera Band Gold - Is the new type any good?

The new formula Thera Band Gold arrived today.

It can be recognized easily, as it is 12,4 cm wide rather than the previous 13,8 cm.

I tested it immediately (but not with the chrony as it is darlk already).

The new type is also thinner (0,67mm vs. the old 0,89mm). But the new type clearly is more dense, with 0,958 g/cm3 vs. 0,828 g/cm3 of the old type.

I then tested the draw weights.

Interesting: The new type can be stretched to factor 7 (600%), the old one ends at 6,5 (550%).

The average draw weight of the new type compared to the old is 74%.



What does this mean?

Well, it is quite clear.

A new formula has been used, simply because the density of the new rubber is 16% higher. Also you can see that it stretches 8% more.

The new rubber is less wide and less thick, so you have to use more rubber to achieve the same draw weight. Use the factor 1,35 for cutting the new bands. So if you used to cut 3cm (fork) x 2 cm (pouch), now you should cut 4 cm x 2,7 cm.

Is it more powerful? It should, just by looking at the data. More dense, longer max. elongation. But the chrony will speak the truth.

  2. Are they changing the formula for all their colors, or just gold? I am not that much into gold bands, I use blue thera band the most, because I do not shoot heavy ammo (9.5 mm steel is the heaviest ammo I use).

  3. I guess they are changing all of the colors. At least I can confirm that the blue, black and silver tubes are different.
