Wilier Adlar

About the Wilier Adlar

The Wilier Adlar isn't trying to win gravel crits. It's built for the rider who wants to disappear into the backcountry for a week - or a month - and come back with stories, not Strava segments. Wilier's carbon monocoque frame is reinforced to shoulder 35 kilograms of luggage without complaint, and the geometry borrows heavily from mountain bikes: a 70-degree head angle and long reach that plant you squarely over the front wheel when the trail tilts down or the surface turns to marbles. You'll find axle-mounted rack points front and rear, a third bottle cage under the downtube, and enough bag mounts to turn the frame into a rolling wardrobe. It's a bike that treats self-sufficiency as standard equipment.

Wilier pairs that load-lugging chassis with up to 52 millimetres of tyre clearance - enough for proper gravel rubber or even a 29-inch mountain-bike tyre if you're heading into genuinely rough country. The fork's extra-length blades let you bolt on a 40-millimetre suspension fork without slackening the geometry further, so washboard fire roads and rocky descents lose their sting. Cable routing is fully integrated, the 1×12 Shimano GRX drivetrain keeps things simple, and the whole package weighs in around 9.4 kilograms for a medium frame. It's not featherweight, but when you're carrying a fortnight's worth of kit, a few hundred grams of frame stiffness pays dividends in control.

This is a bike for riders who measure trips in countries crossed rather than kilometres ridden, who value stability over speed and practicality over podiums. If your idea of a good weekend involves dirt roads that peter out into singletrack, or multi-day routes where the nearest bike shop is three valleys away, the Adlar makes a compelling case.

Wilier Adlar geometry

Wilier's designers clearly spent time studying trail bikes when they drew the Adlar's lines. That 70-degree head angle is slacker than most gravel bikes dare, and it plants the front wheel further ahead of you - think stable rather than snappy. When you're descending loose gravel with 20 kilograms of camping gear strapped to the frame, that extra wheelbase and relaxed front end stop the bike feeling twitchy or nervous. You sit more upright than on a race-bred gravel machine, which takes pressure off your wrists on long days and gives you a clearer view of the trail ahead.

The long reach stretches you out enough to keep weight centred when you're climbing technical pitches, and the relatively short chainstays (for a touring bike) mean the rear wheel stays planted even when traction is scarce. It's not a bike that rewards aggressive cornering on smooth tarmac - you'll feel the extra stability as a slight reluctance to flick through tight bends - but point it down a rutted descent or across a rock garden and the geometry suddenly makes perfect sense. The frame's horizontal top tube and generous standover clearance also make it easier to swing a leg over when you're wearing a loaded hip pack or need to dismount quickly on technical ground.

Wilier offers five sizes from XS to XL, and the stack-to-reach progression is sensible across the range. Taller riders get the same composed handling as shorter ones, and there's enough seatpost extension to accommodate a 27.2-millimetre dropper if you want to add descending confidence to the mix.

Component choices & upgrades

The stock build is already well sorted for its intended use. Shimano's GRX groupset - either 1×11 or 1×12 depending on spec - delivers reliable shifting and powerful hydraulic braking, and the wide-range cassettes (up to 10 - 51 tooth) give you plenty of gears for loaded climbing. The 40-tooth chainring is a sensible middle ground: low enough for steep pitches with luggage, tall enough to keep momentum on flat gravel. If you're planning genuinely mountainous routes with heavy loads, swapping to a 38-tooth or even 36-tooth ring is straightforward and might save your knees.

Vittoria Terreno Dry tyres in 47-millimetre width are capable all-rounders, but the frame's generous clearance invites experimentation. If you're heading into wetter conditions or looser surfaces, a chunkier tread like Schwalbe's G-One Bite or Panaracer's GravelKing SK will add grip without sacrificing too much rolling speed. For truly rough terrain - think rocky doubletrack or rooty forest trails - you could fit a 29×2.0-inch mountain-bike tyre and transform the bike's capability. Just be aware that wider rubber adds weight and rolling resistance, so save it for trips where traction matters more than pace.

The Ritchey Comp Corralitos handlebar offers plenty of flare for control on descents, and the Selle Italia Novus saddle is a solid starting point, though saddle fit is always personal. If you're spending weeks in the saddle, it's worth experimenting with different shapes and widths. The Miche Graff XL wheels are robust and tubeless-ready, which is exactly what you want for bikepacking - swap them only if you're chasing marginal weight savings or need a specific hub standard for a dynamo setup. Speaking of which, the fork includes routing for a dynamo cable, so adding a front hub dynamo and USB charger is a sensible upgrade if you're touring off-grid.

Where the Wilier Adlar excels

The Adlar is outstanding at multi-day bikepacking and expedition touring, particularly on routes that mix gravel roads with technical singletrack. Its reinforced frame and axle-mounted racks let you carry serious loads without the bike feeling overwhelmed, and the mountain-bike geometry keeps you in control when the surface gets rough or the gradient steep. If your trips involve remote dirt roads, alpine passes, or trails where you're more likely to see wildlife than other cyclists, this bike will inspire confidence.

It also handles shorter overnight adventures and weekend gravel explorations well, especially if you prefer a stable, planted feel over outright speed. The wide tyre clearance and suspension-fork compatibility mean you can tune the bike's character to suit the terrain - run slick 40-millimetre tyres for smoother gravel, or fit knobbly 50-millimetre rubber and a suspension fork for rougher stuff. The 1× drivetrain's simplicity is a bonus when you're miles from a workshop, and the integrated cable routing keeps things tidy even when the bike is festooned with bags.

Where the Adlar is less ideal: fast group rides on tarmac or smooth gravel. The relaxed geometry and load-carrying stiffness mean it doesn't dance up climbs or carve corners with the same eagerness as a lighter, racier gravel bike. If you're chasing personal bests on local loops or joining spirited club rides, you'll find the Adlar feels a touch ponderous. It's also not the bike for pure road touring on sealed surfaces - the wide tyres and slack angles are overkill when you're sticking to asphalt, and you'd be better served by a traditional touring frame with narrower clearances and a more upright position.

Wilier Adlar FAQs

What is the maximum load capacity of the Wilier Adlar?
The frame is reinforced to carry up to 35 kilograms of additional gear, distributed across front and rear racks, frame bags, and bottle mounts. That's enough for extended self-supported tours with camping equipment, food, and spares. The axle-mounted rack system transfers weight directly to the hubs rather than stressing the frame, which helps maintain handling even when fully loaded.

Can I fit a suspension fork on the Wilier Adlar?
Yes, the fork's extra-length blades are designed to accommodate suspension forks with up to 40 millimetres of travel without altering the frame's geometry. This lets you smooth out rough gravel or light singletrack without sacrificing the bike's stable handling. It's a worthwhile upgrade if you're tackling washboard surfaces or rocky trails regularly.

What type of bottom bracket does the Wilier Adlar use?
The frame uses a Shimano Press Fit 86.5×41-millimetre bottom bracket. It's a common standard that works with most modern cranksets, and replacement bearings are widely available. If you prefer a threaded bottom bracket for easier maintenance, you'll need to use an adapter sleeve.

What is the tyre clearance on the Wilier Adlar?
The frame and fork clear up to 52-millimetre (700c) gravel tyres or 29×2.0-inch mountain-bike tyres. That's generous enough to run proper off-road rubber for challenging terrain, or to fit mudguards and still have room for 45-millimetre tyres underneath. The wide clearance also lets you drop tyre pressures for extra comfort and traction without risking pinch flats.

Is the Wilier Adlar suitable for long-distance touring?
Absolutely. The reinforced carbon frame, stable geometry, abundant mounting points, and wide tyre clearance make it an excellent choice for multi-week tours on mixed surfaces. The 1× drivetrain's simplicity reduces maintenance, and the bike's ability to carry heavy loads without compromising handling is a key strength. If your tours involve rough gravel, dirt roads, or light singletrack, the Adlar is particularly well suited.

Can I mount fenders on the Wilier Adlar?
Yes, the frame includes mudguard mounts and is compatible with Wilier's own mudguard range. The generous tyre clearance means you can fit full-coverage guards and still run 45-millimetre tyres, which is ideal for wet-weather touring or commuting. There's also a small integrated mudguard formed by the seat-tube shaping, which helps keep spray off the drivetrain.

Does the Wilier Adlar come with pedals?
No, the bike is sold without pedals, which is standard practice. This lets you choose pedals that suit your riding style - whether that's clipless for efficiency on long rides, or flat pedals for technical terrain and easier dismounts when you're carrying a heavy load.

What makes the Wilier Adlar's geometry different from other gravel bikes?
The Adlar borrows heavily from mountain-bike design, with a slacker 70-degree head angle and longer reach than most gravel bikes. This creates a more stable, confidence-inspiring ride, especially on descents and rough terrain, and it keeps the bike composed when you're carrying significant weight. The trade-off is slightly less agility on smooth surfaces and tighter corners, but for loaded touring and technical gravel, the geometry is a clear advantage.
