DESIGNED TO RIDE
Beyond the pavement. Into possibility.
Archer
Gravel bicycles are designed to handle both paved and unpaved roads where the surface is less than perfect. Their versatility makes them adaptable to a broad range of riding conditions.
Archer is a central member of BOSKEY’s Gravel family, with a style and performance refined through continuous development. It is suited to commuting, day trips and short tours, as well as light off-road and endurance riding. Versatile, adaptable and ready for all weathers: that is Archer.
THE DETAILS
Care in every detail.
02
Gearing
A 48–32T crankset paired with an 11–34T cassette provides accessible gearing. The established Shimano 105 R7000 drivetrain is welcoming to newcomers and well suited to gravel riding.
03
Tire clearance
Clearance is up to 700×42c, or 700×35c with mudguards fitted. The frame also accepts 650B (27.5-inch) wheels with tires up to 47c (1.75 inches) wide.
04
Wheels
The GravelTech rear hub uses five bearings and six pawls for quicker engagement and responsive power transfer. BOSKEY mechanics hand-build the wheels for stiffness and durability under demanding use.
05
Mounting points
Numerous mounting points work with most bicycle luggage systems, whether you prefer traditional rear-rack panniers or rack-free bikepacking bags for lighter travel.
06
Thru-axles
Front and rear thru-axles, combined with carefully selected one-piece cast dropouts, increase frame rigidity and keep the wheels securely located.
07
Geometry
Comfort-oriented geometry helps reduce pressure on the torso, arms and shoulders, supporting a relaxed position over longer rides.
08
Tubing
A stable frame made from Taiwanese heat-treated, butted chromoly tubing is paired with a Toray T800 carbon fork to reduce weight and deliver a direct response to pedalling.
