The Elara features a carbon monocoque frame with integrated routing and a maximum tyre clearance of 57mm. This creates an interesting contrast between race aero shaping and high volume tyres. The drivetrain is electronic-only, which keeps the cockpit clean but limits mechanical options.
Running the widest tyres a frame permits usually improves comfort and flat resistance, but it is unclear if those gains conflict with the intended aerodynamic benefits of a race frame. If the tyre volume is that significant, it might overshadow the shaping of the carbon tubes.
Does the aerodynamic advantage of a race frame remain meaningful when using high-volume 57mm tyres?
I think the aero advantage of the frame still matters, but you have to look at the total package. A monocoque shape helps with the airflow around the main tubes, but 57mm tyres are basically huge air brakes compared to a standard road setup. If you are pushing for maximum speed, those tyres will definitely be the limiting factor regardless of how optimized the carbon is. That said, if the goal is a race where comfort and grip are the priority, the aero frame still gives you a marginal gain over a traditional boxy gravel frame.
That's a fair point about the tyres acting like air brakes, but I wouldn't count the frame out entirely. Even if the 57mm rubber is the biggest drag factor, the airflow around the tubes still matters for the overall efficiency, especially if you aren't riding through a mud pit. My main interest is that the Elara gives me the option to swap down to 32mm or 35mm for something faster without the frame being a bottleneck, which a dedicated gravel bike might not handle as well.
The flexibility is fine on paper, wannatour, but you might be chasing a compromise that doesn't actually exist in a race scenario. If you're running 32mm or 35mm for speed, you're basically trying to turn a gravel-specific aero frame into a road bike. If the frame's geometry and tube shaping are tuned for the stability and clearance requirements of 57mm rubber, you might find that the handling or the weight penalty of that ''versatile' layup works against you when you're actually trying to ride fast on 32s. You end up with a bike that's a jack-of-all-trades but a master of none, which is a dangerous place to be when the pace picks up and you need precise handling through a technical corner.
I get where you’re coming from, but my experience with the Elara on 32‑35mm tires has been that the handling stays surprisingly sharp. The carbon layup does add a modest weight bump compared to a pure road race frame, but it’s only a few hundred grams – nothing that throws you off in a technical corner at race pace. The tube shapes are indeed tuned for the extra clearance, yet the bike’s fork‑to‑rear‑stay angles stay within the range that gives you the confidence of a road bike when you drop the tyre volume. So while it isn’t a dedicated road machine, the aero‑gravel platform delivers enough precision for fast riding without turning into a “jack‑of‑all‑trades” that feels unsafe.
The problem is that you can't just tune tube shapes for clearance without affecting the actual geometry. If you design a frame to accommodate a 57mm tyre, you are likely looking at a longer wheelbase or a different head tube angle to keep the handling predictable under load. Trying to shrink that footprint back down for a 32mm setup by just 'adjusting the layup' doesn't change the underlying geometry. You might feel it's sharp, but a bike designed for the stability needed for heavy, wide rubber isn't going to have the same snap as a dedicated road frame, no matter how much carbon you throw at the layup.
Halflin, you’re overstating the link between tyre clearance and geometry. A carbon layup can tune compliance and torsional stiffness without changing the fork-to-rear-stay angles or wheelbase. That’s why the Elara still feels precise on 32–35mm tyres, those angles stay within the road-bike range even when the frame is built for 57mm rubber. The geometry doesn’t shrink back, but the ride character can still behave like a road bike when you drop the tyre volume.
Wannatour, you can't layup your way out of geometry. You can make a frame incredibly stiff or incredibly compliant, but you aren't changing the wheelbase or the head tube angle just by playing with carbon orientation. If a frame is built with a longer wheelbase to keep a 57mm tyre stable, it is going to be less agile than a dedicated road bike, regardless of how 'precise' it feels on 32mm rubber. You're essentially arguing that the ride feel can override the actual geometry, which just isn't how physics works when you're cornering hard.
MTBRaider, it isn't a matter of physics being overridden, it's a matter of how the rider experiences the resulting dynamics. I'm not suggesting you can magically change the wheelbase by choosing a different carbon layup, but I am saying that when you drop down to 32mm tyres, you are removing the primary driver for that stability-focused geometry. The bike isn't going to magically become a dedicated road racing machine with a twitchy wheelbase, but it certainly doesn't feel like a sluggish gravel bike when you're on thinner rubber and a more compliant layup. It's about the threshold where the frame's characteristics and the tyre's footprint balance out, and in my experience, the Elara sits comfortably on the 'precise' side of that line even when the clearance is largely unused.
No, rider perception doesn’t rewrite the bike’s wheelbase or head‑tube angles. Swapping to 32 mm tires removes some of the tyre‑generated stability, but the frame still carries the longer chainstays and slacker head angle that were set for 57 mm clearance. In a hard, technical corner that geometry will still lag a true road‑oriented bike, regardless of a softer layup. What feels ‘precise’ is largely the result of compliance in the fork and the brake system’s modulating feel, not a change in the bike’s moment of inertia or steering geometry. If you count on consistent bite in mud or grit, you can’t erase the penalty of a longer‑wheelbase design simply by dropping tire volume.
