Now available with disc brakes with no aero penalty
We're seeing a lot of uptake with disc brakes, but unlike
Specialized and Cannondale who have fully committed to disc brakes,
Trek is aiming to keep all of its customers happy by offering the
choice of rim or discs. Which you choose comes down to personal
preference, and we like that. Choice is a good thing.
Disc brakes have their advantages, and they are gradually
winning us over, they aren't without their drawbacks. Trek has
worked to ensure the new Madone with discs offers no aerodynamic
penalty compared to the rim brake Madone.
Adding disc brakes has an impact on the aerodynamic performance,
and addressing this was pivotal to the new Madone, as Trek
"Disc brake adoption was a critical pillar during the research
and development phase of the new Madone. Aerodynamics and brake
hose routing were two areas that needed to be addressed and
"On the aerodynamic side, disc brakes become a concern when
considering wind at yaw on the non-drive side of the bike.
Maintaining fully internal hose routing required Trek to explore
unique ways to route both the rim and disc brakes through the lower
head tube bearing.
"To overcome this obstacle, Trek bonds in a routing tube to
easily push brake hose from the fork leg up to the steer tube for a
trouble and tool free experience."
Disc brakes usually mean increased tyre clearance, and the
Madone is designed around a 28mm tyre.
It's lighter too
Aero bikes commonly come with a noticeable weight penalty
compared to regular lightweight road bikes. A Tarmac or Emonda
builds into a much lighter bike than a Venge or Madone.
"Trek went to great lengths to ensure the new Madone frame could
aid in reducing or maintaining bike weight from the current
Madone," it explains.
"The effort resulted in a bike that has additional features that
benefit the rider, and is as fast and light as the current
That means the rim brake Madone weighs the same 7.1kg as the
previous model, but with the extra features of adjustable IsoSpeed.
For the disc brake Madone the company set a 7.5kg target which it
"Bike weight is a tangible feature that athletes and consumers
greatly care about. Creating one of the best all-around aero race
bikes requires a delicate balance of aerodynamics, frame stiffness
and by extension of those two, the bike's weight," says Trek.
