KALAS PASSION Z1

£99, kalas.co.uk

If you want to ride like a pro, you need to go aero. Kalas’ Passion Z1 is made for going fast, with a snug, streamlined fit. This tightness can cause a bit of discomfort if you don’t have the physique of, say, Chris Froome. But as they say, no pain, no (marginal) gain.
