The Flyer goes disc and wide clearance, making it the ultimate foul weather winter bike - or sharp stopping city bike.Now based on our best-selling CDA frameset, the Flyer now has our hybrid double-butted alloy tubeset at its heart.A clever mix of two differing grade alloys help give us high levels of stiffness in certain areas and compliance in others.Helping aid comfort and all-terrain ability even further are the 37mm-wide tyres, smoothing the ride whatever the surface.Matched to the simplicity of the singlespeed setup, this is our one bike that minimises maintenance, cleaning and adjustment, leaving you more time to get on with riding.
