Surly has released the new Ghost Grappler, a drop-bar off-road bike with trail-ready geometry that wouldn't look out of place on a mountain bike. It's designed to take on everything from bikepacking adventures to singletrack sessions and gravel riding.
Surly says this new steel-framed bike builds on the customised setups it's seen riders experimenting with over the years and “captures a more confident, nimble and reactive off-road/drop-bar experience.”
The Ghost Grappler can be seen to take up the mantle in Surly’s range of the ECR (Extreme Camping Rig), which similarly covered bikepacking and more technical riding. According to Surly’s website, no future production of the ECR is planned.
The Ghost Grappler will be available as a frameset retailing for £850 / $799 / CAN$1,149 or as a complete build with a dropper post and Microshift Advent 1×10 drivetrain for £2,200 / $1,899 / $2,599.
Bikepacking to singletrack
The Ghost Grappler can be seen to fit into a an emerging category of drop-handlebar off-road bikes, following the recent releases of the Cotic Cascade and Sonder Camino.
The Cascade and Camino have similar cross-terrain and cross-discipline ambitions to the Ghost Grappler. They are said to be suitable for bikepacking, with frames inspired by mountain bike geometry, yet are still described by Cotic and Sonder as gravel bikes.
Surly doesn’t describe the Ghost Grappler as a gravel bike first and foremost, but the Ghost Grappler is positioned as an off-road-ready alternative for bikepackers and for trail riders who prefer the familiarity of a drop-bar.
While people have been experimenting with fitting drop handlebars to mountain bikes for years, Surly says putting drop bars on bikes designed for flat bars isn’t always comfortable.
Looking at the proposition of designing a drop-bar bike ready for trail riding from a different starting point, maxing out the tyre size on a cyclocross bike may not be the strongest or safest choice on technical terrain, according to Surly.
Consequently, Surly says it has blended what it knows from developing drop-bar and flat-bar bikes to optimise the Ghost Grappler’s geometry, achieving a “comfortable and stable sweet spot” and “optimal drop-bar hand position”.
The bike has a higher stack height and longer reach than similar-sized bikes in Surly’s range, which is said to improve fit and handling. Compared to the outgoing ECR, the Ghost Grappler’s stack height has increased by 20mm and the reach has increased by 9.5mm in a size medium.
Adaptability and mounts galore
The Ghost Grappler has a number of design features to make it adaptable and suitable for different types of riding.
Surly says the steel frame, built from the brand’s proprietary Natch tube sets, has a double-butted main triangle, plus top-tube gussets for added strength, and so the bike can handle rough terrain.
There are mounts dotted across the bike, providing plenty of spots to attach bags and bottles, as well as racks and mudguards. The front forks have four mounting points on either side and mounts on the underside of the down tube.
The seatstays have unusual vertical sections coming up from the dropouts, and these have mounts for bottle cages, too. This feature is on all frame sizes apart from extra-small, where presumably the vertical section isn’t long enough for a bottle cage.
Surly has built the frame with its Gnot Boost rear-spacing design, allowing riders to run standard 142mm or Boost 148mm mountain bike rear-axle standards.
The bike also has horizontal dropouts, so riders can run the Ghost Grappler as a single-speed bike. But despite the dropout design, the frame has thru-axles on the front and rear wheels for “ideal stiffness and handling”.
While Surly has specced its complete Ghost Grappler with 27.5in wheels, it says you can run the bike with 29in wheels too. The frame has 2.8in clearance with 27.5in wheels – with or without fenders – and 2.1in clearance on 29in wheels without fenders.
The Ghost Grappler can be fitted with a dropper post and Surly says there is “stealth” cable routing.
