Rapha is the latest to tease a new range, recently promoting the "Pro Team Flight" which it claims is 'highly technical... ideal for racing and training in warm weather'. The teaser photo seems to see a textured or even ribbed material in a colourway not dissimilar to the oil slick crit jersey they briefly had in the market a couple of years ago.
Rapha says the new range is a special edition, which suggests it won't be around for too long.
