RidleyThe team are experts in all bike materials but it was this aluminium number that drew admiring glances from the Bristol crowds. “It’s a fixed-gear bike we made for hill- climber Joe Norledge,” explains Ridley. “That’s why it weighs just 5.1kg – and that’s with pedals and a power meter.” which continuesThe is heart also withof reallythe the bikeraw stiff. alu is That superlight remaining lightweight scandium unpaintedtheme alloy, and unlacquered to save a further 300g. Bead-blasting the graphic also saved a gramme or two. It’s pretty extreme but things could have been even more severe. “We had some crazy ideas about drilling the bottom bracket to make it lighter but we would have sacrificed a lot of that power transfer and the handling,” says Ridley. “It’s what the hill climbers of the late 60s and early 70s used to do; they used to drill holes in To pay homage to times every gone component.”by, Engineered decided on a pattern that looked as if someone had indeed drilled holes in Joe’s bike. “Each ‘hole’ is offset at 60° because that’s structurally sound,” adds Ridley, “so if we were to drill the frame, that’s exactly where we would drill it. In short, we’ve properly nerded it out!”
