4ZA is the in-house components arm of Belgian bike brand Ridley, are the firm’s aiming high in its own right with a handful of interesting new products for 2015.

4ZA products are split into three tiers: Stratos, Cirrus and Cirrus Pro, with the latter being the highest quality they have to offer. 

On the wheels side, they’re right on trend with wider rims and they now come built around DT hubs as well. They’re also getting re-branded rims, although the set at the show were decaled up like the old Cirrus Pro wheels, hence the lack of pictures.

4ZA also have a new shape for their saddles that currently extends to the Stratos and Cirrus models. They’ve re-designed the profile to make it more accommodating in the three main riding positions and call it the ‘Dynamic Comfort Shape’. Contact is focused around the sit bones, and the semi-round shape aims to maximise the support area, and minimise the stress areas. There’s also a recessed channel down the centre which also aims to reduce stress on the genital area.
