A very popular choice for racers, these wheels are awesome for any type or road riding and even triathlons. These are Emma Jacksons favorites for racing World Cup triathlons around the world!

Available in the Black on Black rims and there are small quantity of the White on Black rims available too. These can be ordered with either black or blue hubs (Very Limited!!)

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.

Amazing in every aspect

Having had a discussion with Nathan it was established that the C28’s would be the most suitable Wheelset for my needs, and I am very pleased with the quality and performance. Remarkable build quality!
