Dusty RR

The Mondraker Dusty is an e-gravel platform built with a clear mountain-bike influence rather than a road-first interpretation of gravel. Introduced for 2023 and carried forward without a redesign, it uses a carbon frame around the Mahle X20 rear-hub system with a non-removable 350 Wh battery, 12x142 mm rear spacing, flat-mount brakes, internal headset routing, and compatibility for either 1x or 2x drivetrains. Mondraker’s defining choice is its adaptation of the brand’s Forward Geometry to drop-bar use: a notably slack 70° head angle, relatively long reach, and short-stem layout that pushes the Dusty toward technical descending stability instead of quick, road-style handling.

That positioning makes the Dusty distinctive in the lightweight e-gravel segment. While many rivals aim to feel like slightly assisted all-road bikes, the Dusty is designed to be more confident on rough tracks, loose descents, and light singletrack. The core platform also supports several interpretations of that brief, from rigid drop-bar models to more aggressive variants such as the suspension-fork Dusty R and flat-bar, utility-oriented Dusty X. With rack and mudguard provisions, multiple mounting points, and a standard 27.2 mm seatpost, it sits as an adventure-focused, off-road biased e-gravel bike for riders who want discreet assistance without giving up technical capability.

Fit and geometry

The Dusty’s geometry is unusually progressive for a gravel bike and explains much of its ride character. Across the size range, Mondraker uses a 70° head tube angle, a 74° seat tube angle, 425 mm chainstays, and wheelbases from 1034 mm in S to 1110 mm in XL. Reach numbers are long for the category at 393 mm (S), 405 mm (M), 424 mm (L), and 440 mm (XL), while stack runs from 548 mm to 628 mm. On a size M, the 405 mm reach paired with a 1056 mm wheelbase points to a stretched front center and a more centered rider position than a traditional gravel bike. In practice, that supports high-speed stability and front-wheel confidence on steep or loose descents.

The short 425 mm chainstays keep the rear end from feeling sluggish, so the bike is not purely a long-wheelbase plow machine. Combined with the 70 mm BB drop, the geometry should give a stable, planted feel without making the bike awkward in mixed terrain. The tradeoff is predictable: the same slack front end and long wheelbase that calm the bike at speed will generally make it less eager in tight, low-speed direction changes than a steeper, racier gravel bike. Riders coming from mountain bikes are likely to find the fit and handling intuitive, while road-oriented gravel riders may find it longer and more off-road biased than expected.

Builds

The available build data is incomplete, so only limited conclusions are possible. Listed builds include Standard at $5,999, R Early at $6,799, and an RR build at $8,799, along with references to S, R, and RR variants without complete pricing. Based on the broader model information and reviews, the Dusty range spans from simpler rigid-fork bikes to more premium specifications, with the RR positioned as an upper-tier option.

Where reviewer detail helps fill in the picture, the range appears to separate itself through drivetrain level, wheel spec, and whether the bike leans more toward pure gravel or technical off-road use. Reviews specifically mention SRAM Rival on lower models, Rival AXS XPLR on the RR, and more aggressive equipment such as suspension and dropper posts on top-end versions elsewhere in the range. Without a complete official build sheet for each listed model, a precise trim-by-trim comparison would be speculative, but the available evidence suggests the lineup is structured around the same carbon/Mahle X20 platform with escalating component quality and off-road intent.

Reviews

Reviewers were broadly aligned in describing the Dusty as a gravel bike with unmistakable MTB DNA. Publications including Rennrad-news, Bikeboard, Gran Fondo, and off-road.cc repeatedly pointed to the combination of Mondraker’s Forward Geometry and the Mahle X20 system as the bike’s defining trait. Testers praised the natural feel of the motor, noting that the assistance comes on proportionally rather than with the abrupt surge associated with stronger mid-drive systems. Several outlets also highlighted the lack of drag once assistance cuts out at 25 km/h, which helps the bike maintain a conventional pedaling feel despite its electric assist. Across rigid and suspension-equipped versions, reviewers also commended the low overall weight for the category, with figures cited from 12.8 kg up to roughly 14.3 kg depending on build.

The strongest praise centered on descending composure and technical-terrain confidence. Reviewers described the bike as stable, sure-footed, and unusually capable on steep or rough gravel, with comments such as running "like on rails" at speed. The XR in particular stood out for its 40 mm RockShox Rudy Ultimate fork and 75 mm Reverb XPLR dropper, which off-road.cc and Gran Fondo said gave it a distinctly MTB-like feel and let riders carry more confidence into rough descents and technical sections. At the same time, testers noted limits to that approach: Rennrad-news found it less lively in tight asphalt turns, some found the 440 mm-plus bars overly wide for flatter road riding, and Gran Fondo argued the XR’s suspension-led setup can feel like overkill on easier gravel. Reviewers also mentioned that the rear end can feel less cushioned than the front on rough descents, partly attributed to the hub motor’s unsprung mass.
