Redesigned Madone is the best of all worlds, according to the US brand

Trek are launching a new version of their Madone road bike that is designed to be both ultra light and ultra aerodynamic; the US brand claims that the 2013 model puts in a market-leading all-round performance.

We’re in Belgium for the launch at the moment and we’ll be riding the new bike tomorrow. In the meantime, here are the highlights…

Aerodynamics

Trek have completely redesigned the Madone frame to incorporate aerodynamic tube profiles borrowed from their Speed Concept time trial bikes.

The fork blades, down tube, seat tube, and seatstays are all shaped to Trek’s Kammtail Virtual Foil (KVF) design. Check out our Speed Concept review for the full story on the design. In short, it’s an airfoil shape with the rear of the tail chopped off, yet the air travels in much the same way as if the tail was still there.

The advantages of the design are that it allows Trek to stick within the UCI’s equipment rules that limit the width to depth ratio of tubes, it saves weight, it and isn’t massively affected by crosswinds.

Trek have also brought in a completely new brake design in the name of aerodynamics. The front brake still sits at the front of the fork in the usual way but it’s much more integrated than a traditional design. One arm is attached at the fork crown and pivots centrally but the other one mounts directly to the fork leg.

The rear brake has been redesigned too, and it now sits beneath and behind the bottom bracket – as you’ll find on many TT bikes – where it’s more sheltered from the wind.

Moving the brake calliper away from the seatstays has allowed Trek to dispense with the brake bridge altogether. Check it out. It certainly looks strange to start with. Trek have been able to remove reinforcing layers of carbon from the seatstays too because there are no longer any braking forces in that area.

Trek claim that compared to the previous generation Madone, the new version has 330g less drag. That means you can go the same speed as before for 25W less effort (that’s at 40kph/25mph with a wind at 10° yaw). Or, for the same effort, a ride that would previously have taken an hour now takes 57:56mins, according to Trek’s figures.


Weight

The new Madone is the lightest ever, the top level frame coming in at just 750g. That’s superlight by anyone’s standards. To put it in perspective, the previous generation Madone was 915g – so the new one is a whopping 18% lighter.

Trek would like you to bear in mind that most other mega-light frames aren’t built to be aerodynamic. If you want an aero frame, you’re usually looking at well over 1,000g.

U5 Vapor Coat

If you really want to save every gram, you can go for a Madone with Trek’s new U5 Vapor coat, which is a superlight finish. A typical paint job might add somewhere between 40g and 80g which ain’t a lot, granted, but if you’re after the ultimate, that’ll never do.

With the U5 Vapor Coat, there are no transfers and Trek use the absolute minimum of paint. You’re looking at a weight of 5g.

Other features

Lots of brands have been working hard lately to keep a dropped chain from damaging your carbon and Trek have been doing their bit too. They’ve come up with their 3S integrated chain keeper which mounts directly to the Madone’s frame via a threaded hole just north of the bottom bracket. It’s a pretty minimalist design but Trek reckon it does the job.

The cable routing is internal and Trek integrate an Duotrap sensor into the non-driveside chainstay that you can link up to a wireless computer. 

And finally

Trek are massively excited about this bike. Company President John Burke said at the launch in Spa, Belgium, that, “This is the most amazing bike Trek have ever come out with.”

And Trek’s pro riders Frank Schleck, Jens Voigt and Chris Horner all said good things at the launch too.

“I felt in two pedal strokes that it was something different,” said Jens, who saw prototypes a year ago and at various stages in the development process.

Of course, you cynical bunch will say that they would say that, wouldn’t that? And you might be right. We’ll find out tomorrow how all the changes stack up when we get to ride the new bike. Trek reckon that it offers the best combination you can get of high compliance, low drag, high frame stiffness and low weight, so they’re promising a lot.

The top level Madone on the previous incarnation was a 6 Series; this time Trek are pushing things up a level with the 7 Series which is what the Team RadioShack riders will be using. The KVF tubing and all the key features will be available on the 6 Series and 5 Series too. The bikes will hit the market from the end of July.

Meanwhile, Trek has released a short video in which some of the design team involved in the bike talk about its aerodynamic features, and which also includes comments from RadioShack-Nissan riders including Chris Horner.
