I was wondering if you had the stiffness rating for the Radical Twin Tube Tour OS and if the Trysis OS grommets would fit the TT Tour.

Thanks in advance.

Hi Doc!
According to the USRSA the stiffness rating for the Radical Tour TwinTube 690 XL is 53. There is no stiffness rating for the standard length for some reason. I would think it would be the same for the standard length as well because USRSA had stiffness rating for both the Radical Tour TwinTube 630 XL and Standard Length and both were 58.

The Radical Trisys 260 oversize, Pro Tour 690 (AKA Pro Tour 280 Oversize), and the Radical Tour TwinTube 690 (Oversize) all come from the same mold so the grommets are interchangeable between these racquets.
