The world’s lightest production road bike gets the full factory treatment for the Tour

First rolled out under a couple of riders at the Critérium du Dauphiné, the Emonda was officially launched at the Tour de France.

With three models it’s hardly a surprise that Trek Factory Racing are using the top of the range SLR frameset that even in production form weighs just 690g for a size 56cm.

Of course, the UCI still has its minimum weight limit of 6.8kg for the complete bike, so the factory had to get inventive about adding weight to its super-light racing machines.

The full white paint scheme adds close to 100g, then the team mechanics have a set of adjustable lead weights to add inside the hollow Dura-Ace bottom bracket, which can add up to 350g. For most frames this is sufficient but on the smallest frame they still have another 70g of lead that bolts under the bottom bracket to ensure it’s legal.

Early Tour casualty Andy Schleck had been through the whole bike fit system as he’d got 4mm (wider) axles fitted to both his pedals to broaden his ‘Q’ factor. With Trek/Bontrager as sponsors, the components are a hometown affair.

The production bike’s built-in chain-catcher remains for the race bike both to protect the frame and protect against any mechanicals caused by a dropped chain.

How neat do you want it? Using a threaded insert the hollow Dura-Ace axle gets up to 350g of lead and alloy ballast added, but you’d hardly know from the outside.

Andy runs an extra 4mm on his pedal spindle length to get the perfect ‘Q’ factor. Few riders in the peloton run anything other than standard.
