No excuses

I don't have any excuses any more, these wheels are light and stiff and roll true and forever. Its now down to my legs! Great to see a local wheel builder doing good things. Highly recommend buying direct rather than via numerous middlemen, result being the consumer ends up paying margin on margin.
