THE LONDON BIKE SHOW All under one roof The London Bike Show is favourably looked upon in the trade as a chance to


benefit from the curiosity of the neighbouring Triathlon and Outdoor exhibitions, but plenty more can be taken from the show as Mark Sutton finds out…


KEITH BONTRAGER: “ROAD DISCS ARE THE FUTURE”


SPEAKING TO the crowds on the Cycling performance Theatre’s main stage, cycling pioneer Keith Bontrager revealed that he thinks the road disc revolution could come as soon as next year. With many road builds on the show floor already embracing discs, Bontrager said: “I’ve been developing brake pads for decades – we need disc brakes on road bikes to maximise the potential of the carbon rim. Pros do things that ordinary riders just don’t and I expect that pro cycling will embrace the disc as soon as next year once the UCI makes a few rule changes. “Having worked with Fabian Cancellara, I’ve watched him destroy a pair of carbon rim pads in a single Vuelta stage. From a thermodynamics point of view it was a big mess. The weight of discs on pro bikes won’t be an issue, I mean at present we’re adding weight just to meet the regulations.” Bontrager also revealed that he has had technical input on a

2014 attempt on a planned hour record by Fabian Canellara. On this he said: “The UCI restrictions here are significant. The bike almost needs to be like a ‘70s Merckx. We’ve got 20mm box section rims that we’re trying to make aerodynamic. To have a chance of challenging we are having to go into some serious detail – like how little friction can a bearing possibly have. “Minimising energy losses is


critical for such a challenge, we may even be removing grease from the bearings just for a minute gain.”


“Around a third of the 120 who came to the ICS were medical


professionals keen to learn about cycling’s impact on the body...” Phil Cavell, Cyclefit
