When the Cervélo Áspero was developed and launched it changed the gravel game. Up until then, gravel bikes were either cyclocross bikes outfitted for gravel racing or “adventure” bikes with a bajillion mounts for racks and bags and usually “endurance” geometry designed for comfort.
But that’s not what competitive gravel racers want. They want a bike that they can race on gravel. Enter the Cervélo Áspero. A gravel race bike designed to race on gravel! They want fast, responsive geometry. They want a light, stiff frame. They want a frame that uses all of the aerodynamics to their advantage. And that’s what Áspero delivered without asking riders to sacrifice anything.
Flash forward to today and Cervélo has updated the Áspero with the all-new Áspero 5 lineup of gravel race bikes! Lighter, faster, more aerodynamic. And drop-dead gorgeous. Let’s get into it.
The Cervélo Áspero is a gravel race bike. This isn’t a beefed-up adventure bike with tons of mounts for bags and whatnot and a relaxed geometry. This is a refined high-performance gravel bike. The geometry is road-race inspired with a remarkably steep headtube angle for a gravel bike and clearance for up to 700×42 or 650×49 tires.
But there are times when riders (racers) want to run a narrower tire. Some courses call for 700×33 or 35 tires, which can be mounted on Áspero as well. Sometimes you want to run a 650b wheel and tire. But, when you make these changes, you change the trail enough that you throw off the handling because the fork is now in a different position, depending on the tire size.
That’s where the Trail Mixer Fork comes in!
This is essentially a “Flip Chip” for the front axle that changes the rake by 5mm. Set it in the rear position when you are running 700x35ish tires and set it in the forward position for 700x42ish tires. In the end, the optimal trail of 62mm will be accomplished to keep the front-end handling snappy and predictable!
The Cervélo Áspero 5 has been further refined to take all of these refinements and dial them up a notch. The engineers came up with a design for the Áspero 5 that is even more aerodynamic, saving you 32grams of drag when you’re out there, all alone, slogging it out into those headwinds.
The front end of the Áspero 5 is one clean machine. No cables means no drag. All of the cables are beautifully hidden inside the frame.
Finally, the carbon fiber layup of the Cervélo Áspero 5 has been completely updated to remove material where it isn’t needed and using a higher modulus material, dropping the already incredibly low weight. Cervélo claims that the new Áspero 5 comes in at 990g for a size 56, a weight savings of approximately 120g over the previous Áspero frames! You can even save 50-60 grams by choosing the minimalist black paint option.
The result is a remarkably low weight, extremely aerodynamic, fast gravel race machine!
Cervélo Áspero 5 is available in three versions and a frame-only option.
