the ultimate aero road bike now designed for a 2x electronic drivetrain.
the same blend of stiff perfectly aero frame and superb comfort thanks to the 30mm tyre clearance but this time with the added benefit of 2x compatibility so you can use your favourite electronic drivetrain.
wide tire optimisation
the biggest factor in road bike comfort are the tires; they provide more compliance than any other part of the bike. Wider tires are better at reducing shocks from cracks curbs cobbles and potholes which is why they are the norm at paris- roubaix. Wider tires also have lower rolling resistance because their shorter contact patch requires less bending by the casing.
in addition wider tires offer an advantage on long and multi-day rides reducing the steady drain on a rider's energy level caused by high-frequency road buzz. But aerodynamics are also important on such rides and wide tires tend to test poorly in the windtunnel. However that is to be expected if you test them with frames and parts optimized for narrow tires. The strada is the first aero road frame optimized for wider tires so finally you can be fast and comfortable all the time from the cobbles to the climbs. All day every day with one and the same bike.
double duty
you probably know 3t strongly believe in 1x drivetrains for many riders and situations. But they also know there are riders and situations where 2x still makes more sense. With the strada due 3t have worked hard to keep the seattube as narrow as on the original strada so that the airlfow is disturbed as little as possible by the addition of the front derailleur hanger and the derailleur itself.
the strada due is only compatible with electronic drivetrains. Without limitation it is compatible with all SRAM etap and Shimano Di2 road groups. For campagnolo eps please note that its seatpost battery is very long so on smaller sizes there is a limit to how low you can position the seat before the battery touches the curved part of the seattube.
realfast aerodynamics
at 3t they design for real world aerodynamics at realistic speeds. This means they test at 20mph (32kmh) and 30mph (48kmh) they test with bottles and other "difficult parts" for aero optimization and sometimes they even test dirty and muddy bikes.
but most importantly 3t want to design frames that are fast with realistic tires. It's no use that a bike tests fast with 21mm tires if the rider puts 25's on. It's even worse if the rider would have preferred 28mm tires that don't even fit!
after 17 years of co-founder/owner of cervlo most people think the head of design gerard vroomen is all about aerodynamics. And they aren't completely wrong; the strada is full of aero details including some like the front and rear wheel cutouts that are more commonly seen on time trial bikes.. But ask him what is is most proud of and he'll tell you it's how those aero features have been optimized so people can run up to 30mm tires. Because the comfort of the wide tire in combination with unbeatable aerodynamics - the one bike for everything - is his real passion.
