Cervelo is typically a name that we associate with ultra light or exceptionally fast bikes with skinny tires. And while the C-Series attempted to expand their horizons a bit with clearance for up to 32mm tires, Cervelo still lacked a true “gravel” bike in their line up that was capable of running even bigger tires. Enter the new Áspero – a gravel bike meant to “haul ass, not cargo.”

In spite of the big tires, the Áspero seems to still be uniquely Cervelo. The bike is unabashedly aimed towards pure speed over any terrain, rather than trying to offer a multi-purpose gravel/bikepacking rig. That means that while the Áspero is capable of running the biggest tires for a Cervelo yet, it’s still limited to 700c x 42 or 650b x 49mm tires with 4mm of clearance. Each complete bike ships with Donnely X’Plor MSO 700c x 40mm tubeless tires.

To allow for proper handling of both wheel sizes, the forks feature a two position “Trail Mixer” to adjust the trail to best suit different tire sizes.

Compatible with 1x or 2x drivetrains, the full carbon frame runs flat mount disc brakes, a 1 1/8″ to 1 1/2″ tapered fork, BBright bottom bracket, and 12 mm thru axles front and rear. As it’s meant for speed and not gear, you’ll only find standard water bottle mounts with two inside the front triangle, and it looks like a third can be mounted to the bottom of the downtube.

Four complete builds are available starting with the Apex 1 Disc at $2,800, then the Ultegra RX Disc at $4,000, the GRX Disc also at $4,000, and then the Force Etap AXS 1 Disc at $6,000. Framesets will also be available starting at $2,500.

    There is also the bottle/accessory mount on the Top Tube similar to their P-series bikes. Just built one of these the other day and was pretty impressed.

  2. Andrew Rockwell on

    Hmmmm 42cm chaninstays…. I need to do some geometry checks here…could this be a cheaper alternative to an Open UP?

    • roadstain on

      One would think. It is not like Cervelo does not own so much “intellectual property of Gerard and Phil. What would be funny is if it was published as “proprietary” like so many Italian bikes of yore. As if a protractor was impossible to get……

  3. Greg on

    Weird about the Ultegra RX and also GRX, I feel something is mixed up there.
    Also interesting is the 1-1/2 lower bearing. So far they’ve been 1-3/8 all the time.
    Otherwise I’m all about it.

    • SJC on

      Most likely the Ultegra RX stuff was already purchased when GRX was announced. Either that or they’re not sure which one people will want more.

      • Brian on

        Availability issues with the GRX components made them build some with the Ultegra RX. Once the GRX is consistently available the Ultegra RX will go away

    • Dinger on

      I wondered the same thing. Might’ve been clearer to do a 105 bike and a GRX 800 bike, but GRX 800 & Ultegra are very close to being the same thing, especially with the Easton crank.

      Neat bike, seems like a more reasonably attainable version of the OPEN UP.

  4. schmamps on

    Hmm, no mention of fenders, and I don’t see a tube bento mount, which I kind of want instead of muddy food stuffed in jersey pockets when I’m 20 miles from a road with services.

    • Hexsense on

      Big tire want to push the chain stay out, but chainring is in the way, so the chainstay have to dive under the chainring first then widen out.

  5. Evan Stade on

    How does weight and aerodynamics compare to, say, the S3, with road wheels and tires? Of course all gravel bikes can be ridden on the road with slicks but this looks like a decent candidate for someone who wants a light, aero, racy road bike with just a swap of wheels.

  6. Pancho on

    It does have bento mounts apparently. I love the gold.colour. But it’s possibly even more racey than a UP. Sounds lighter than a UP at 1100g full frameset. The Apex version looks much better value than a frameset.

    • Greg on

      The UP is 1040g. This is 1100. That’s for the painted frame with hanger and stuff, not for a frameset, which would include the fork.

  7. Jeff on

    When I see a bike like this I wonder why the manufacturer didn’t just go one small step further and put in mounts for fenders. It just seems like they are turning their backs on a potential market segment. It wouldn’t be much trouble, they wouldn’t need to change the basic bike they made at all, just have some way to add fenders. I’m not trying to single out this bike or this manufacturer, I see it from most manufacturers.

  8. Eric in the 505 on

    Or…you could just get a mountain bike to ride throiugh streams, over rocks, etc. (You should check ’em out. They’re pretty cool!)

  9. Michael on

    Looks like a nice bike, but you have to wonder why they though they should give it a lower stack for any given reach that their road racing bikes

    • Gary on

      Frame stack figures are spot-on identical across the size spectrum to the R3/S3, but reach is 10mm more across the board. I’m guessing they either spec a 10mm shorter stem or 10mm shorter reach bars?

      • Evan on

        My guess is toe overlap. Cervelo road bikes have unusually short reach for their stack so toe overlap is already an issue, add 40mm tires and you might have real problems.

        • Dan @bikeinsights on

          Hard to say with certainty since they don’t publish the precise front-center depending on the fork offset used. But I’d say it’s as much about handling since they push out the reach/front-center even for the larger sizes which have no real risk of toe-overlap.

  10. Gillis on

    The “Trail Mixer” feature looks like a copy of the Rhondo version, albeit smaller in effect. I think I saw a Giant using the same tech. Does Rhondo have a patent? Are they licensing it?

  11. Velo Kitty on

    Nice frame other than the:
    1. proprietary bottom bracket
    2. front center distances that are too short for anything larger than standard road tires
