Why suffer for speed? Strada is the fastest bike, designed around bigger road tires…
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.
Paradigm shift: 1xAero
With all aero road bike developments of the past 20 years, the drivetrain was never really tackled. So we did. The BB area – with frame, crank, chainrings, front derailleur, water bottles and rider legs – leaves little room for the air to pass through. A single ring drivetrain eliminates the front derailleur and inner ring. Thus it reduces frontal area and creates space for unobstructed air flow. And with modern cassettes (in particular the 3T Overdrive and Bailout), you still have all the gears you need.
Just think about it, 30 years ago we had 12 gears (2×6) of which only 8 were unique (the rest overlapped). Now we’re at 2×11 or even 2×12 but riders barely notice when they upgrade to an extra cog. Sometimes more is not better, it’s just more. 1x gives you the gears you need, the range you need, less complexity, less weight, less drag and less hassle.
For those who love the Strada’s speed and comfort but still prefer electronic or 2x drivetrains, we offer the Strada Due compatible with Shimano Di2, SRAM eTap and Campagnolo EPS. So the 1x Strada offers ultimate aerodynamics and comfort while the Strada Due let’s you use any of the major drivetrain brands’ electronic groups with a small aero penalty for the front derailleur and second ring.
As the co-founder/owner of Cervélo, our Head of Design Gerard Vroomen loves aerodynamics. But rather than just theory, he’s interested in real world aerodynamics. So we test at 20mph (32kmh) and 30mph (48kmh), we test with bottles and other “difficult parts” for, we sometimes even test dirty and muddy bikes. But while the aero details of the Strada range stand out, he is proudest that it has started a worldwide trend towards more tire clearance on aero bikes.
Unfortunately such bikes now may have CLEARANCE for 25mm or 28mm tires but they are still aerodynamically OPTIMIZED for much smaller tires. So you pay an aero penalty for bigger tires. What sets the Strada range apart is that it not only fits 28-30mm tires, it is aerodynamically optimized for those widths. Comfort & speed!
