Hi ppl ! Just wanna share something i found on some japanese website. Sorry. I can't put overseas competitor links here. You can google: My Colour speedport tuning system Just click on japanese website. Basically, it allows you to customise the colour of the speedport of your racket. Seems like it's only available for speedport black. The customization is purely for beauty/aesthetic. No performance benefit. I just find it quite cool. So, wanna share with you ppl. Wonder if this will be available outside Japan.
